Pordrän

Pordrän , 2.5 x 30 meters

Pordrän is a completely impermeable geotextile that prevents water from reaching the foundation wall under high groundwater pressure or due to the water spread angle in deeper trenches. In sloping terrain and for trenches deeper than 3 m, Pordrän is used along the vertically installed Pordrän instead of Pordrän . However, Pordrän must not be unfolded and used over the drainage layer at the bottom of the trench; Pordrän must be used there.
