Turf reinforcement from the rootzone up, StaLok® Fiber gives three dimensional strength and stability to sand and soil. The fiber act as a mass of indestructible roots that provide a shield like structure to the root zone, preventing the surface from breaking up and eroding. This is done through triangulation- spreading a point load across a larger area in the rootzone. Natural grass roots grow together with StaLok Fiber, creating a network that spreads surface loads across a broader area, increasing load bearing strength.
