Drainage Cell is a lightweight, efficient and multifunctional drainage product used in foundation drainage, tunnel lining, slope protection, underground structure drainage and other projects. It usually consists of a high-strength plastic frame structure as the internal skeleton, filled with gravel, pebbles, sintered ceramsite or synthetic filter material, and wrapped with a permeable non-woven geotextile or woven mesh to form a complete structure, with good water collection, water conduction, filtration and compression resistance.
