- “Ballast” is defined as a heavy material used to improve stability and maintain balance and steadiness. In the turf world, the term Ballast is used to “Weigh down the turf, prevent wrinkling and give the entire turf system stability and longevity. Properly placing infill assists the turf fibers in maintaining vertical position.
- “Thermal expansion” is defined as the tendency of matter to change in shape, area and volume in response to a change in temperature through heat transfer.
“Understanding these two concepts will play a major role to successful installations in hot summer months”
The infill material’s granular size, weight, and how its placed is very important for ballast. I teach installers a close-up view of how to properly infill synthetic turf. I take a small bucket and hand place infill so they can learn how much infill is to placed, the proper depth, and how it feels on the foot, in comparison to synthetic turf that has NO infill. It is critical to understand what it takes to “ballast” each and every synthetic turf product that your company is offering. Educating your team about different infill types, sizes and placement are steps towards preventing wrinkles. Avoid using materials like beach sand, coal slag, dirty silica, fine cement sand. By utilizing the correct infill and amount, you can avoid wrinkling and be proud of your installations
