U S Tiles & Allied Products provides an intelligent solution to the problem of permanently destroying green space to build occasionally used parking areas or fire and emergency roads. The design for open areas allows ground cover to grow while still providing the necessary structural strength for any traffic. U S Tiles also provides excellent erosion control and soil stabilization to slopes, embankments, low flow channels and dikes, ponds or reservoirs where there is no extreme wave action. Strong as concrete, sweet as grass.
