Drain cell, also drainage cell, is made of high polyethylene raw material in a flexible, honeycomb design of subsoil HDPE modular drainage layer.
Drain cell has a flat black which is pressed against an underground structure such as a basement wall or subsurface footing providing high compressive strength yet lightweight modules for subsurface drainage purpose. Drain cell is the suitable geotechnical material that can create a permanent, non-clogging void between the concrete slab and the soil profile that will not collapse or distort. The pressure of backfilled soils holds the drainage cell in place. The optimized void enables a direct flow of water to designated outlets avoiding the risk of water build-up and penetration. The large surface and capacity void space enables superior drainage efficiency compared to the small voids created by using a gravel system. Generally, there will cover a layer of filtration geotextile upon the drainage core to allow the unrestricted flow of moisture into the core, while it restricts the passing of soil particles which may clog the core. It's a good choice for vertical applications where require moderate compressive strength and flow capacity are adequate.
