SCP Wall Drain



Walldrain consists of a preformed lightweight plastic core bonded to a geotextile filter. The filter was specially developed to permit free entry of water, but not soil, and so prevent soil particles from clogging the drainage system. Walldrain is designed to be placed with the geotextile filter layer facing the direction of water seepage or backfill. Walldrain can be applied against waterproofing membranes or directly against the masonry/concrete substrate.


Walldrain relieves hydrostatic pressure against the vertical walls of buried structures - basements, retaining walls, reservoirs, tunnels, bridge abutments, culverts and underground car parks. Walldrain provides a second line of defence to channel seepage water away from the structure and is designed to fully comply with the requirement of type 'C' design BS 8102.
