Pordrän

Pordrän floating membranes are used on the perforated pipe where the footing extends beyond the ground surface, or between the bedrock and the foundation wall if the building is founded on bedrock.
Pordrän membranes are also used against the foundation wall in cases where the ground level above the foundation must be backfilled with a layer thicker than approximately 50 mm, which would otherwise cause moisture penetration.
Liquid-applied membrane, available in 5 kg and 10 kg packages.
