Drainage Material is the material that can remove the excess water from land by means of surface or subsurface conduits, pipes, or other systems. Drainage is needed to prevent the built up of hydrostatic pressure against or on top of buildings or civil engineering works that causes structural overloading, humidity and leakage problems.

Delta
Made of a special type of polyethylene, Delta dimpled sheets form highly efficient seepage and drainage layers. They are compression-resistant, maintaining their outstanding hydraulic properties even under heavy and permanent loads. The fused-on Geotextile layer of the multi-layered Delta dimpled sheets filters soil particles out of the seepage water, thus preventing the air gap from becoming clogged up.
CollDrain®
CollDrain® is a synthetic drainage material with a high drainage capacity even when under high pressure. Designed to be practical and light-weight, CollDrain® materials are easy to handle and installed compared to sand or gravel – saving both time and money.
