Drain cells are lightweight, modular drainage systems made from high- strength materials like polypropylene or HDPE. Their hollow, interlocking structure creates void spaces that facilitate efficient water flow and storage. Benefits:- Effective Water Management: Facilitates rapid water movement, reducing the risk of structural damage.- Light weight & Easy Installation: Simplifies handling and reduces labour costs.- Eco- Friendly: Often made from recycled materials, promoting sustainable construction practices.- High Load- Bearing Capacity: Suitable for areas requiring both strength and water management.
