Wavin Twinwall infiltration pipes are slotted to allow controlled infiltration as water is transported along their length. This reduces the volume of water that needs to be drained at the endpoint and facilitates groundwater re-charging.

Wavin TwinWall pipes have a ridged wall profile which offers advantages over smooth-wall pipes. The ridged wall profile is proven to increase infiltration capacity, and has been both lab and field tested.
