Underdrain

Underdrain Banner

Underdrains can be used to capture and discharge rising high groundwater and eliminating hydrostatic pressure build-up. They can be used when natural soil infiltration rates are not sufficient enough to prevent an area from flooding. 

When an underdrain is used, water can be collected from the ground where it is then transported to a collection drain. 

Utilising Underdrain as an application

Rainsmart 30mm Drainage cells are commonly used as an underdrain to capture stormwater that may lead to flooding. 

The high load-bearing capacity of our cell modules make them ideal for parking lots, roads and building foundations that may get affected by high groundwater.
