Turf Tek Direct offers a high quality, fracture-proof, quartz sand, or silica, infill. It avoids the harmful off-gassing of crumb-rubber infill and the unpleasant odor and dust often associated with rubber materials, and with no lead or heavy metals, it’s the most environmentally friendly infill product on the market. Our infill has no static cling, unlike rubber infill materials that stick to clothing, and it doesn’t float – eliminating concerns about hazardous runoff. The quartz sand infill helps the turf grass blades stand upright, assists in drainage and keeps the turf about 15-17 degrees cooler than a crumb rubber infill.
