Platon DOUBLE DRAIN is a vertical drainage layer for external basement walls and a protection board to primary membranes. It consists of an impermeable studded sheet, manufactured from high-density polyethylene with a polypropylene filter fabric bonded to the top of the surface of the studs.
Channels between the studs form an air gap against the underlying structure. Platon DOUBLE DRAIN forms drainage layers on both sides of the studded core sheet. The filter fabric facing the backfill material ensures the drainage channels are not blocked or obstructed.
Platon DOUBLE DRAIN can be fixed vertically or horizontally to suit the application.
