Terram standard geotextiles enhance the performance and design life of granular layers by providing filtration and separation functions. Typical uses for Terram standard geotextiles include ground stabilization (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.
Terram filters/separators are used extensively in the construction of Paved and unpaved roads, Railways, Car parks and hardstanding, Cycleways and footpaths, SuDS installations, Green roofs
