ROCK SOLID: Rock GX, Polyfelt's new generation of rock geogrids, offers improved product stability and tensile strengths up to 400kN/m.

Developed for reinforcement of road base courses and railway track, the grids are made of high strength polyester yarns with a polymeric coating. The new range will partly replace the Rock G line and be manufactured in Polyfelt's new plant in Bezons, France.
