- Geosynthetic material formed into a very open, gridlike configuration and used to reinforce soils below roads or structures.

Permeable fabrics consisting of synthetic fibers which, in association with soil, have the ability to separate, filter, reinforce, protect or drain. They support many civil engineering applications including roads and railways.
