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
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.
