WPA Drainage Cell

About WPA Drainage Cell

91 000 74051 Drainage cells are lightweight, interlocking modular units, typically made from recycled polypropylene, designed to create a crucial void space beneath surfaces for efficient sub-surface water management. This interconnected network allows water to flow horizontally towards drainage outlets, preventing waterlogging in green spaces, reducing hydrostatic pressure against structures like retaining walls and basements, and facilitating stormwater runoff in paved areas. Their high compressive strength supports overlying layers, while their ease of installation and environmental benefits, such as the use of recycled materials and contribution to sustainable drainage systems, make them a versatile and valuable component in various landscaping and construction applications.
