Platon Double Drain protects the underlying waterproofing against damage from the backfill. The interior drainage channels reduce hydrostatic pressure on the waterproofing. The exterior drainage layer and a filter fabric provide permanent high capacity drainage. Platon Double Drain can also be used as an independent damp protection in combination with a drainage system along its lower edge.
Advantages
Double drainage both inside and outside
The air gap controls damp pressure and accidental entry of water
High capacity drainage layer is protected by filter fabric
Flexible and strong material protects the waterproofing from the pressure and impact of backfilling
Floating drainage and protection layer is unaffected by cracks in the building structure
Reduced hydrostatic pressure on waterproofing
