Turf Tips for Cold Weather Installations

When the weather outside is frightful, your cold weather install can be more delightful with these turf tips, brought to you by our Installation Professional, Joe Wadkins! Stay tuned for more in-depth cold weather installation tips in his January “Ask J.W.” feature story!

1.) Always store your rolls of synthetic grass so the freezing temperatures will not leave flat spots in the turf roll. If you have to store the turf outside, rotate the roll occasionally to prevent flat spots from occurring.

2.) Be sure to store all water-based adhesives in a warm environment. This will maintain the glue’s viscosity (thickness) as well as providing a more pliable substance to work with. A water-based adhesive may possibly freeze under cold weather conditions and subsequently cause seam failure. I recommend SGW SuperSeam Pro Glue for all of your seaming needs as it has been tested and approved for conditions colder than 32 degrees Fahrenheit.

3.) Before cold weather arrives, roll out your synthetic turf and allow it to lay flat on the prepped surface to remove any wrinkles. This will make your installation more efficient and prevent cold weather stretching.

Ask JW: Incorporating Tree Wells Into Your Install (Part 1)

Your Turf Installation Will Survive for Years to Come, But Will the Trees, Plants, and Shrubs Within Your Installation?

A basic understanding of a root system’s structure is critical. Trees, plants and shrubs depend on a consistent supply of water, oxygen, and nutrients for survival.

This month I will explain why encapsulating trees, plants and shrubs with synthetic turf will not only put the vegetation in a health risk, but the repairs and replacement can also be costly.

Contractors must understand the liabilities of all surrounding areas within their installation, in addition to the synthetic turf area. Installing synthetic turf against the base (crown/flair) of trees, plants and bushes without regard for the surrounding vegetation will only create unhappy customers.


Tree– A perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species.

Shrubs– A shrub is a small to medium-sized woody plant.

Plants – Any of various photosynthetic, eukaryotic, multi-cellular organisms characteristically containing chloroplasts, having cell walls made of cellulose, producing embryos, and lacking the power of locomotion. Plants include trees, bushes, herbs, ferns, mosses, and certain green algae.

Tree (Circle) Well– The primary purpose of a diameter(circle)constructed well is to retain moisture for re growth and to prevent the tree from certain causes of death due to the raising and lowering of elevation of soils surrounding the tree.

Encapsulating– To surround or close off on all sides

Crown/Flair– The root flare area (also called the crown or root collar) is that area where the main stem tissue transitions to root tissue.

Roots– The roots of a tree serve to anchor it to the ground and gather water and nutrients to transfer to all parts of the tree. They are also used for reproduction, defense, survival, energy storage and many other purposes

Canopy – Is the aboveground portion and collection of individual plant crowns.

Mulch – Is a layer of material applied to the surface of an area of soil. Its purpose is to conserve moisture, to improve the fertility and health of the soil, to reduce weed growth, to enhance the visual appeal of the area.

Since trees, plants and shrubs require carbon, hydrogen and oxygen from the air and water to survive, there is little turf installers can do to control how much of these plants receive. Installing synthetic turf directly up against a plant will diminish its chance of longevity and survival.

One of the best ways to protect the health of trees is to ensure that there is a constructed “Circle Well” around the base of each plant.

The “well circle” that is constructed around the plant provides a nice contrast to the surrounding synthetic turf, but most importantly, the well circle allows the plant to access vital nutrients for survival.

The additional space between the plant and the turf helps protect the plant, the inner bark, roots and flair near the soil line.

Constructing a raised well will also prevent water runoff and allow for deep penetration of the irrigated area. Mulching tree wells is also important for maintaining healthy vegetation. Mulch retains root moisture for trees, plants and bushes. The diameter of the mulched area surrounding the tree should extend as far as roots are visible.

When natural grass is removed and replaced with synthetic turf, trees, plants and bushes can fall within the “Synthetic Turf Zone.” This vegetation either is receiving water from its own irrigation system or feeding off the natural grass irrigation system. My recommendations are as follows:

1. I strongly recommend to cap all irrigation lines at the valves that connect to the existing natural grass irrigation. DO NOT USE SPRINKLER CAPS! Sprinkler caps only cover the heads of the natural grass sprinklers. If the irrigation valve is not capped, there is a chance that nails, spikes or staples may puncture the underlying irrigation lines which may be buried unseen to the naked eye. I have experienced contractors getting call backs three years later from the client stating there are leaks throughout the synthetic turf zone. Don’t take this chance!

2. If there are trees, plants or bushes within the synthetic turf zone that were receiving water from the natural grass sprinklers, I recommend drawing out a new irrigation plan and installing new irrigation pipes or drip tubing. This will ensure that all workmen understand where the new irrigation lines are placed as well as prevent any irrigation damage caused by nails, spikes and staples that water the trees, plants and shrubs.

The drawing will also provide the contractor and homeowner future reference of the new irrigation’s location. These simple steps will allow for easy future repairs.

3. Synthetic Grass Warehouse Polyboard is a quick and great solution to create tree wells. When the natural grass is removed and irrigation is completed, prior to the placement of sub base materials, measure the SGW Polyboard at an even radius around the base of the tree. Excavate and bury the SGW Polyboard to proper elevation to complete a tree well. On larger trees, the well must extend to the “canopy”–also called the “drip edge,” which is where the feeder roots gain the most nutrients. The well must be made of good soil that will compact and allow the well to hold water without it breaking its circle.

Please note; if the constructed well is not installed with SGW Polyboard or SGW Wonder Edge, integrity of sub grade soils will erode and will allow the exterior nails, spikes or staples to come loose and the “circle well” will fail.

4. If SGW Polyboard or SGW Wonder Edge is not used, then a “berm” can be constructed to create a “circle well.” Build up the soil higher than the existing turf elevation to keep water and nutrients from running away from the trees, plants or shrubs.

Place the synthetic turf into the well approximately 8 inches. Use a tape measure and chalk and mark an even circle around the well. Trim excess turf off.

Use a claw hammer and excavate the interior of the well approximately 3 inches deep at the perimeter of the synthetic turf edge. Curl and tuck the synthetic turf into the soil with nails, spikes or staples to secure the edge.

Ask JW: Zeolite, a Perfect Complement to Your Infill

Photos By: Chemistry World

Many installers ask “Why can’t I use Zeolite as the primary infill”?

That’s a good question.

Although opinions vary, Zeolite is NOT considered a primary infill because it is not heavy enough to be used as a primary infill.

Infill provides stability for synthetic turf. Zeolite is primarily used as an added infill, which is placed under the turf as well as at the base of the fibers to manage odor control. Zeolite is the #1 choice for pet turf areas for odor control. Zeolite is not made to withstand heavy traffic to keep fibers in a vertical state. The granular structure resembles a “honeycomb” appearance and does not constitute a stable grain to be installed as a complete infill. Zeolite should be mixed with SGW Envirofill or SGW Round Premium Silica (RPS) infill.

When Zeolite is wet, it absorbs up to 81% of its original weight in water and 55% of its weight in urine. However, once the granule dries out, it returns to its original state and is not heavy enough to keep the synthetic turf ballasted, which may allow wrinkles in the turf.

Under a microscope, Zeolite resembles a “honeycomb” structure. It is much softer infill than Envirofill or Silica sand. Because Zeolite becomes softer after it absorbs liquids, it is not a good candidate to be used as a 100% infill for synthetic turf.

The Mohs scale of mineral hardness characterizes a mineral’s scratch resistance through mineral’s ability to scratch a softer material. Below I have provided you each infill’s measurements on this scale for comparison.

  • Zeolite: 4-5
  • Silica Sand: 6-7
  • Envirofill: 7-9

SGW Envirofill

I recommend to pair Zeolite with Envirofill and let Envirofill serve as the primary infill to ballast synthetic turf. Envirofill is made of a moisture resistant coated silica.

Envirofill is made of an acrylic coated silica sand and repels moistures in addition to unpleasant odors associated with our pets. Because of the anti-microbial coating, Envirofill inhibits the growth of micro-organisms. Envirofill is a colored and sealed silicon dioxide (SiO2) and is free of dust. The rounded, uniformly sized beads reduce abrasiveness to surrounding turf fibers by up to 50 percent while allowing movement within the synthetic turf.

Most silica sand is fractured and angular which causes it to compact easily with heavy rain fall and foot traffic. This may cause premature wear at the fiber’s bending point at infill level. This constant action will create memory loss in your synthetic turf.

Envirofill comes in small and large granules, is available in 50 pound bags and sold exclusively through SGW.

SGW Round Premium Silica (RPS)

SGW Round Premium Silica sand is my second choice for infill. The Round Premium Silica Infill is not a fractured/angular silica and is the latest in silica infill technology.

Product Features:

  • Naturally occurring exceptionally round mono-crystalline quartz (silica) resists abrasion in high traffic/ excessive wear application.
  • Double washed and screened to ensure uniform size distribution (no dust) and consistent grain shape.
  • Dried to less than 0.1% Moisture content before bagging
  • Sold in 50 pound bags
  • Natural Brown Color

Product Benefits:

  • Less compaction than fractured angular silica
  • More volume per pound
  • Cooler to the touch
  • Easy to handle 50 pound bags.

Realistic “soil” look blends nicely with artificial turf thatch–no more white sand drifts.

My recommendations for placing infill in synthetic turf is as follows:

On pet applications, I recommend placing approximately ¼” of Zeolite on your compacted subgrade. Place approximately 1 pound of Zeolite per square foot as the first lift (stages) to the base of fibers, then place 1-1/2 to 2 pounds per square feet of either Envirofill or SGW Silica for ballast.

For synthetic turf that will not experience pet traffic, I recommend placing approximately 1 pound of Envirofill per square foot or 1-1/2 to 2 pounds of RPS sand per square foot. See the turf’s infill requirements on each individual spec sheet. All of SGW’s synthetic turf product spec sheets are available for download on the SGW website, click here to download!

Be sure to broom or rake all infill in steady lifts. If the turf will experience heavy foot traffic, mix SGW Envirofill to allow proper movement of the fibers to prevent premature matting.

By installing infill in lifts (or stages), this will help prevent trapping the turf fibers and ensure a beautiful installation.

When the installation is complete, the infill level should be approximately ½ inch below the fibers.

Ask JW: Pet Turf Systems: Not All Are Created Equal

As fun and loving as pets are, our four-legged friends can often create dead spots throughout natural grass and, as a result, high maintenance and stress for pet owners. Consider replacing the natural grass lawn to synthetic turf. Not only will the grass always be greener, but it will also prevent unwanted insects, dirt and bacteria from entering the home.

This month “Ask J.W.” will show you how to use the proper pet turf system for either single pet or multiple use systems using SGW Pet Turf Products that will work for you.

Here are a few basic concepts:

Why Does Pet Urine Smell?

Dog urine is a concoction of ammonia, bacteria, hormones, and uric acid. As the urine breaks down, the ammonia concentration increases and then mercaptans (extreme odors) are produced. This is the same chemical compound that gives skunks their ability to keep away predators. Uric acid contains crystals that are left behind even after the urine has dried. These crystals are reactivated anytime new moisture reaches the area, including humidity or after a heavy rainfall. A dog’s urine also acts as a scent marker designed to let other animals know this territory is taken. This potent combination gives dog urine its staying power long after the spot has dried and is the reason specialized dog urine cleaners are so indispensable.

It is very important to fully grasp the sub surface conditions below the area where your animal usually does their “business.” In order to have a successful pet installation, proper drainage is very important and necessary.

In reference to my June 2015 column, please consider these important factors.

These types of subgrade soils should be recognized prior to installing SGW Pet turf to allow the best drainage possible:

  • Caliche -(ka-lee’-chee) is a sedimentary rock, a hardened natural cement of calcium carbonate that binds other materials—such as gravel, sand, clay, and silt.
  • Rockbound– is bouldered, inflexible, hard, stone like
  • Clay- is a type of heavy soil when becomes wet and hardens when it dries
  • Loam– is soil composed of a mixture of sand, clay, silt, and organic matter.
  • Sand– is a loose pale brown substance that you find at a beach or in the desert, formed from very small pieces of rock
  • Silt-is sand, dirt, and very small rocks that are carried from one place to another by moving water
  • Subsurface groundwater flow– is when the soils become saturated due to water intrusion.

***Let’s Begin!***


If you have a pet turf installation dedicated to single or smaller animals, I recommend a clean drainage material which consists of a mixture of sand and aggregate (rock). This sub base material that is placed under your pet turf should allow good compaction and great permeability. You should place a minimum of 4 inches.



For pet turf areas with multiple pet use as in hotels, resorts, pet kennels and commercial applications, proper ground preparation is required and necessary. I recommend over-excavating the sub-base materials underneath the pet turf and place a minimum 6 inches of ¾ inch clean crushed aggregate. Compact with a plate compactor to flatten. This will allow for proper drainage and water runoff below the pet turf when cleaning the pet turf area.

ask-jw-03 ask-jw-04









Place 2 inches of either decomposed granite, chat or a clean sand on top of the aggregate. This will serve as a sand cushion below the pet turf system. Compact this material with a plate compactor to prepare for the next process of the placement of SGW Drain Core.




ask-jw-06When the sand cushion is compacted, place the SGW Drain Core on top using SGW Nails or SGW Staples. Be sure that you do not drive the nails or staples too hard or they will leave divots in the drain core system. On larger projects, join the sections of Drain Core together as close as possible.




Remember to carefully drive the nails or staples into the Drain Core, otherwise your installation will experience a dimpled appearance once it is complete.

ask-jw-09 ask-jw-10After the installation of your SGW Pet Turf System, place a mixture of small Envirofill and Zeolite Max into the fibers for ballast. This will also give your pet turf system the maximum protection for your pet. For commercial use I recommend that additional Zeolite Max be placed within the fibers when the granules either get removed by foot traffic, run off or cleaning of the system over time. Take a broom and work the Envirofill and Zeolite Max into the pet turf evenly and prevent from over filling which traps the pet turf fibers.

ask-jw-11Envirofill is the leader of infill products on the market today. It will not allow animal urine, blood and vomit to absorb in its granule. Envirofill eliminates the adhering and absorbing of bacteria spores.






SGW Drain Core

SGW Commercial Pet Turf System is designed for multiple animals that use the area daily and utilizes a five step process to drastically curtail odor issues by focusing on aeration, drainage, neutralization and, of course, beauty.













Designed and designated for areas where maximum drainage and all-weather use is imperative, the perforated drain core system can collect and transport as much as 16 gallons of fluid per minute.

ask-jw-14Perforated Drain Core is the most aggressive drainage system for pet turf installations. Non-Perforated Drain Core is developed for indoors over concrete where it provides the ultimate in odor control and drainage. It is a great solution for commercial kennels/pet day care centers and for residences where there is kennels that need to be installed over concrete flooring.

To adhere the Non-Perforated drain core over concrete, make sure the concretes surface is clean of dirt and debris and place SGW Superseam Pro Glue with a 1/8” notched trowel. Roll the Non-Perforated Drain Core with a water roller or weight for compression. This will allow for the Drain Core to adhere and lay flat. This will allow years of longevity and prevent uplifting of the drain core. Place your chosen SGW Pet Turf on top. Non-perforated Drain Core separates the artificial grass from the concrete and directs the waste to a predetermined drainage to allow the urine and waste to reduce odors and prevents buildup of possible bacterial. Additionally, the Drain core system has the capacity to drain over 4 inches of rain water per hour. When installing each section place SGW Drain core sections as close as possible prior to gluing with Superseam Pro Glue.

ask-jw-15For maintaining and cleaning of your new pet-friendly lawn, I recommended to use SGW Turf Fresh as needed. The more pets that use this area, the more you will want to keep the area clean and smelling good for years to come.

“Your pet will love his newly placed SGW Pet Turf system and will never want to leave.”

Installer Tip: Before installing SGW Weed Fabric below synthetic turf, the subgrade should be free of debris and rocks to allow the fabric to lay flat and conform to the compacted subgrade materials.



weed barrier gapStep 1:

Roll out the weed fabric parallel to all hardscape like concrete, pavers or curbs. Stretch the weed fabric so that the surface will be wrinkle-free. It is very important to place the weed fabric adjacent to all hardscape to prevent crab grass and broad leafed weeds from growing through any edges. Any gaps in the weed barrier will allow vegetation to sneak through.


sgw staplesStep 2:

Secure the weed fabric with SGW staples and/or SGW nails every 2-to-3 feet in the center and 1 foot on center around all edges. I recommend SGW staples because the fabric will stay more secure through foot traffic and the elements.

Ask JW: Avoiding the Putting Green Wrinkle Effect


Over the years, hundreds of synthetic turf putting greens succumb to a “wrinkling affect” due to improper installation. The biggest cause behind these wrinkles is often due to improper infill amount along with temperature changes.

Whether you are installing texturized or slit-film (a.k.a. fibrillated) turf, it is critical to understand what it takes to “ballast” the product as well as “negative thermal expansion’s” role for a successful putting green installation.

Critical Terms to Remember

  • “Ballast” is defined as a heavy material used to improve stability and maintain balance and steadiness.
  • “Negative thermal expansion” is defined as the tendency of matter to change in volume in response to a change in temperature through heat transfer.

These two concepts will play a major role to a successful putting green install, wrinkles not included.

***LET’S BEGIN!***

When installing putting green materials, it is important to lay the turf roll flat for a couple of hours prior to installation so the putting green’s surface will flatten.

**Please remember: If you expose wrinkled synthetic turf to UV sunlight and other harsh environmental conditions for long periods of time, this will cause the synthetic turf to memorize its shape and therefore make these wrinkles impossible to remove.**

During installation, it must be stretched tightly and secured to flatten any wrinkles. Once the entire putting green surface is installed, it is very important to prevent heavy traffic on the fibers in order to avoid premature matting. Not only will premature matting give the ball an uneven rolling surface, it will inhibit the proper amount of infill needed to ballast the putting green.

I have personally installed hundreds of putting greens and found that the infill material’s granular size is very important for ballast. By educating your team about different infill types, sizes and placement, you will cover a crucial step towards a better putting surface. Avoid using materials like beach sand, coal slag, dirty silica, fine cementsand. A putting green surface always needs a quality infill! By utilizing the correct infill and amount, you can avoid wrinkling and give the end user a professional playing surface.

Be mindful of “static electricity” while incorporating your infill. When using a substandard infill and infill size, the installer must aggressively scrub the infill with either a push broom or fibrillating machines to work the infill below the surface. The excessive scrubbing creates static electricity and causes most infill to stick to the fibers and therefore never reaching the base of the putting green material.

SGW carries #60mesh putting green infill that will quickly drop to the base of your putting green surface. This infill will not only minimize the need to aggressively scrub, but it will also save your installers time and labor to complete the infill process.

A typical synthetic putting green averages around ½ inch in thickness and requires between two and three pounds of infill per square foot. To make sure the surface has a true ballast along with 9-12 Stimp meter rating (measurement for a putting green’s speed), I recommend three pounds of infill per square foot for your putting green.

In order to determine how much infill you will need for your installation, follow this simple formula:

Square foot of your putting green X Recommended Pounds of infill = Total amount of infill needed

For example:

1200 square foot putting green X 3 pounds of recommended infill = 3,600 pounds of infill needed for your job

SGW True Putt product is an exception to your typical putting green as it is a tournament quality putting green and features a high Stimp meter rating. This product acts much like a real bent grass and requires four to five pounds of sand per square foot.

For the SGW Nylon Putt Two-Tone, Poly Putt Two-Tone and Poly Putt Two-Tone Light, I recommend the following:

  • Use SGW’s clean #60mesh Putting Green infill. Try to avoid using an infill that is dusty and powder-like.
  • Invest in a good drop spreader. Most supply houses carry “Scott Drop Spreaders” which cost approximately $60. A good drop spreader will allow the infill to be evenly distributed.

During the infill process, make sure pass with the drop spreader is consistently placing an equal amount of infill onto the surface.

To evenly distribute infill, spread the infill going east-to-west, then north-to-south. Repeat this until all of the calculated infill is placed and has reached the top of the surface where it is visible to the naked eye. For the top dressing, I recommend SGW’s Envirofill (small) which will produce a beautiful green appearance. It will also allow a faster ball speed.

Once you have finished your final sweep, about 1/32 inch of turf should be exposed.

infill-picsAfter the infill top layer in completed, use a water hose with a good nozzle and spray down the entire putting green surface. This will assist the infill to settle in place and bring out the putting green’s surface color.

Your putting greens will look amazing and last longer! Avoid these common mishaps with putting greens and install them wrinkle-free. Stay tuned for next month’s ‘Ask J.W.’ installment!

Ask JW: Staples vs. Glue

The most important part of the installation process is seaming two sections of synthetic turf together. This month I will be explaining why this skill is important as well as which tools to utilize within the installation in conjunction with the many types of sub grade materials.

Critical Terms to Remember:

  • Caliche -(ka-lee’-chee) a sedimentary rock, a hardened natural cement of calcium carbonate that binds other materials—such as gravel, sand, clay, and silt.
  • Rockbound – bouldered, inflexible, hard, stone-like
  • Clay – a type of heavy soil when becomes wet and hardens when it dries
  • Loam – soil composed of a mixture of sand, clay, silt and organic matter.
  • Sand – a loose pale brown substance that you find at a beach or in the desert, formed from very small pieces of rock
  • Silt – sand, dirt and very small rocks that are carried from one place to another by moving water
  • Subsurface groundwater flow – when the soils become saturated due to water intrusion.

If the sub grade soil contains any of the materials listed above, I recommend the seam tape and glue method. By utilizing staples for installation involving the harder subgrade materials, the staples will bend due to the subgrade’s unpliable characteristics and will subsequently cause the turf seam to move. The results will be visible to the eye, so try to avoid staples if the subgrade materials are listed above.

If the soil consists of a soft dirt-like loam, sand or silt, I recommend using the seam tape and glue method, as well. Seams will move over time due to the soils integrity, especially when there is sub-surface groundwater intrusion.

Please Refer to the Products List Below:


This product is a double-sided non-adhesive seam tape that has superior tensile strength, shear and tear resistance. Our seam tape is 12 inches wide and has a plastic film on one side to prevent ground moisture effecting the curing process.

See picture below.

The adhesive should be applied to the dull side of the tape. Synthetic Grass Warehouse seam tape works great for any synthetic turf seaming process. Seam tape is available at any custom length with a maximum length of 328 feet per roll.


SGW nails are available as five and six-inch non-galvanized nails that will absorb moisture and bond to the existing sub grade over time to further secure the turf.


Much like the staples you use to secure paper together, our flat-topped 11-inch gauge staples are much larger and serve a greater purpose in a synthetic turf installation. Often used in the install process as a substitute for glue and seaming tape (when sub grade materials are stable and compacted at approximately 80%), these staples save time with the install process and eliminate the possibility of disfiguring the fibers.


SGW offers two types of turf adhesive: Superseam Regular and Superseam Pro.

This product is a high-performance one-part polyurethane adhesive that is applied to the dull side of seaming tape. After the turf adhesive is applied to the seam tape, I recommend placing infill bags or weight on top of the seam for at least 1 hour to allow compression. The adhesive needs to reach between the gauges underneath the backing.

***LET’S BEGIN!***

Seaming with Staples

When implementing the staples method, make sure your seam is placed together properly as discussed in my May 2015 column: “The Most Recognized Problem in the Synthetic Turf Industry Today: Seams.”

The staples must be a minimum of 4 inches apart down the seam. If they are secured any farther away, the staples cause the turf to “ripple” when the temperatures become hot. Make sure you drive the staple down to the base of the turf’s backing. Add nails in for extra support, as well. Avoid driving the staple down too hard as it will not only create a divot, but it will also cause the seam connection to “lift.”

Seaming with Seam Tape & Glue

If you decide to use the seam tape and glue method, make sure you get both sections of turf together and secure the outside of seam approximately 15 inches with nails (you may pull them after the glue has cured) then place weight on top of the seam for compression for about an hour. If you are using a power broom, always wait until the glue is cured to avoid unnecessary damage or cause the seam to fold.

A rule of thumb: ALWAYS power broom or FIBRILATE your turf parallel to the turf seam. If the turf is power broomed perpendicular to the seam, this will also fold up any area of the seam that is not fully cured.

Do not take any chances! Find out the sub grade conditions prior to any seam installation and choose to use either staples and nails or seam tape and glue for your seaming process.

Ask JW: The Most Recognized Problem in the Synthetic Turf Industry Today: Seams

As the synthetic turf industry incorporates more technologically advanced yarns along with denser more realistic products, it becomes more critical to properly seam turf pieces together.

The design changes have made the process of seaming turf more difficult to hide the two connecting sections of synthetic turf. This month I will educate you about how to install a straight seam by utilizing the Superseam tool.

Critical Terms to Remember:

  • Undetectable: not easily seen, barely able to be perceived
  • Subgrade Soil Stability: the underlying soils being of quality, firm and steadfast
  • Compaction: An increase in the density of something
  • Scrim: the backing of a synthetic turf roll that extends beyond the fibers of each side of the roll
  • Gauge: an outline of rows of tufted fibers stitched into the backing of synthetic turf rolls.
  • Dense Yarn/Fiber Pressure: Increase in density of yarn/fiber creating pressure
  • Synthetic Turf Seam Integration: the action of forming two sections of synthetic turf together to unify as one
  • Seam Reflection: the dynamics of light (sunlight) creating the connected seam to be visible
  • Adhesive Seam Compression: pressure that is applied to seaming area of two sections of synthetic turf onto adhesive glue and seaming tape


Subgrade Soil Stability and its Involvement to a Successful Seam:

soil compactionIt is very important that soils or grading materials that are placed under the synthetic turf be of quality and can reach approximately 80 percent compaction. Compaction is accomplished by vibrating, tamping and rolling the sub-base materials. This establishes a solid base in which to drive the nails while installing the turf.

Common failures to seam ruptures are caused by underlying soils not being of quality, form and steadfast. Substandard subgrade materials that are unstable cause the underlying subgrade to expand and/or contract.

For Example: Soils that have extensive water intrusion, expansive properties, high in fines, low in aggregate, will cause instability. This may cause the seam to move and separate.

Straight Seaming:


It is always recommended to secure and install the seam first prior to cutting the edges and completing the rest of the installation process.

When you roll out the synthetic turf, you will notice the backing of the synthetic turf extends beyond the fibers on each side. This part is called the “Scrim.” Prior to seaming, it is recommended to remove the scrim material unless you plan to sew the seam.

With playgrounds or fields, it is advised to remove the spikes, nails or staples after the seam glue has cured. Nails and staples can work themselves out of the soil and cause injury.

Make sure you acknowledge the measurement between the gauges before you remove the scrim. If the synthetic turf is manufactured with a 3/8” gauge width, then you will want to connect the two section s of the turf together and keep the 3/8” gauge width during the entire seaming process.

If the synthetic turf is manufactured with a ¾” gauge width, then you will want to connect the two sections of turf together and keep this ¾” gauge width during the entire seaming process. This ensures accurate integration without the seam being too close or too far apart.

Please note: The gauge width dimension is from fiber row to fiber row, so when you are seaming the two sections together, you are connecting them per the manufacture’s gauge dimensions. You can find the gauge specifications for each product on the Synthetic Grass Warehouse web site as well as their particular spec sheets.

If the distance between the fiber rows is spaced too wide, not only will the seam be visible, but it will also become very noticeable once you place your infill materials into the synthetic fibers.

Take a sharp turf/carpet knife and cut between the second or third gauges from the edge “Scrim.” Do not cut into the fibers or too close to the fiber row, as this will cause the fibers to fall out from aggressive foot traffic. By cutting two-to-three rows in from the edge of the scrim, this will give the new seam integrity, strength and a fresh edge.

When both sections are placed together at the proper seam width, secure both sections with spikes, nails or staples approximately 18 inches on both sides of the seam. This will prevent both sections from moving while constructing the seaming process and will allow both sections to be folded over for placement of seaming tape.


Depending on the preference, installers may either secure the seam with spikes, staples or nails down the seam edge in a “stitch” pattern.

Always remember: The larger the head of the nail, the more visible the seam will be. Make sure to spread the fibers to allow the head of the nail to pass through the fibers to the base of turf backing or your will create divots by trapping the fibers with the nail heads. This must be a common practice on every nailing procedure.

I strongly recommend placing the adhesive glue on the seam tape early in the morning or late afternoon to prevent yarn shrinkage. The heat of the day will not only cause the seam to expand and contract, it will also cause the synthetic turf glue to set up too quickly or bubble/seep through the seam. You may learn more about yarn shrinkage on the SGW website.

When both sections of synthetic turf are secure and the seam is perfectly in place, fold open both edges of the two sections to expose the subgrade. Place SGW seam tape down the center of the seam and secure with spikes, nails or staples. This will prevent the seam tape from rippling while placing the glue.

**Please note: SGW seam tape is manufactured with a plastic film on one side. This side should be face down and resting on the subgrade materials. The plastic film prevents moisture coming up through the seam tape, which may cause failure. **

SGW carries the best synthetic adhesive on the market today. Superseam Pro withstands freezing temperatures and remains strong and flexible in addition to preventing seam rupture, even during the hottest days.

Place SGW Superseam Adhesive Glue evenly on the seam tape at approximately 1/8” thick.

Depending on preference, installers may either secure the seam with spikes, staples or nails to secure the seam edge in a stitch pattern.

I have always been a firm believer of placing infill bags or weight on top of the seam after gluing for approximately 30 minutes. This will allow for proper compression to allow adhesive/glue to reach the entire backing between the gauges/stitch rows.

REMEMBER: After installing and gluing seams on days with a higher temperature, always inspect the installed seam throughout the curing process. This will prevent the adhesive to bubble/seep up through the seam and drainage holes.



With advanced technology, research and development, synthetic turf manufacturers are creating thicker more realistic artificial grass. These fiber density design changes have made turf seams more difficult to hide in addition to connecting two turf sections. Synthetic turf comes in different styles and thicknesses which changes the seaming process for each product.

The Superseamer tool was invented by myself after experiencing the dreaded turf “Mohawk.” When synthetic turf manufacturers began incorporating the thatch layer (curly fibers between the straight fibers), hiding turf seams became more difficult.

Many installers would over-fibrillate to hide the seam, but would make it worse by manipulating which consequentially dulled the turf and made the seam more visible.

After studying how seams are integrated together, I found that “pressure” was the culprit. Once the scrim is removed, the pressure from the thatch caused the turf fibers to hang outward and when both sections were seamed together, it created the “Mohawk” effect.

The Superseam tool is not for every seam installation, however, when you are installing synthetic turf that has a 50 ounce face weight or greater, don’t take the chance and regret it later. The Superseam tool is available in 6’ and 4’ lengths and can be ordered with a connector bracket. The connector bracket allows the installer to connect multiple Superseam tools together for more efficient seams.
