Here are the benefits of the DELTA®system.

Layer one: Micro-perforated slip film.
This sheet distributes permanent soil pressure. Its micro-perforation allows any water penetrating between the waterproofing and the slip film to escape into the laminated drainage layer.
Layer two: Laminated cloth.
This cloth absorbs impacts and serves as a backup drainage layer. Even water coming in through an imperfectly mounted edge-

sealing strip will be safely drained off.
Layer three: Dimpled sheet with self-sealing edge.
The dimples that face towards the soil create a maximum-capacity drainage layer that covers the entire surface.
Layer four: Permanent-filtration geotextile.
Fused to the dimpled sheet, this filter cloth reliably keeps the dimple structure from clogging up.

Needless to say, we have a range of perfect accessories. For full details about the DELTA®system, consult our DELTA®System Guides.
