Geotextile – Permeable Filter Separator

Terram standard geotextiles enhance the performance and design life of granular layers by providing the filtration and separation functions. Typical uses for Terram standard geotextiles include ground stabilisation (between the sub-base and subgrade) and around drainage materials.

Terram geotextiles provide an effective solution to the problem of constructing a stable granular layer over soft foundation soils. When stone is placed directly on a soft subgrade, the imposed load often causes intermixing of two layers. This results in contamination of the stone layer and a resulting loss in bearing strength, surface rutting and deformation at the sub-base/subgrade interface.

Whether it’s a granular drain or a geosynthetic alternative such as open geocellular units, Terram standard geotextiles are ideal for preventing the ingress of fines.
