Soldrain Double is a twin layered cavity drain membrane, designed to manage water to the land drain, relieving pressure from the structure.
Soldrain Double is a sheet drainage system which consists of a HDPE impermeable studded sheet, with a polypropylene filter fabric bonded to the top of the studded core.
Soldrain Double can be used as a protective barrier between the structure and the surrounding fill and act as a protective layer to the primary waterproofing membranes.
Soldrain Double relieves the hydrostatic pressure by channelling the ground water away from the structural waterproofing, protecting the structure. The filter fabric facing the backfill material ensures the drainage channels are not blocked or obstructed.
Soldrain Double is a UV stable and reliable root and fungi-proof drainage system, which when fully protected from UV exposure, has a design life in excess of 120 years.
Soldrain Double offers levels of protection required for below ground structures, described in: BS 8102:2009
