Drainage Geocomposites

Drainage geocomposites are rapidly replacing gravel drainage layers in containment facilities. These relatively thin materials are required to provide similar or better performance than thick mineral layers. Comprehensive testing is carried out to prove their equivalence to thick gravel drainage layers.
