Geotextiles are a branch of geosynthetic products made from PP or polyester. Used under the surface they can increase the load-bearing and lifespan of roads, driveways, embankments and drainage ditches. Resistant to soil acids and alkalis and impervious to fungi or rot, they come in two types; woven and non-woven.
In short, geotextiles have three key functions; separation, reinforcement and filtration and protection and drain. Projects using these products spend less on materials, less time on excavation and it is less likely you'll need to return to repair minor defects.
