DELTA Drain is a range of external dimpled geocomposite membranes for protection of primary waterproofing and drainage of groundwater.
There is a permanent risk associated with all earth-boundary construction elements, such as foundation walls: They may easily become damp and/or wet. This is why safe damp/waterproofing is of such outstanding importance in this context: DELTA Drain membranes provide reliable surface drainage for cellar and retaining walls as well as roof gardens by filtering out fine-grained soil particles, ensuring constant water drainage, and permanently protecting foundation walls.
Our external geocomposite membranes
NP-Drain – External waterproofing membrane that drains groundwater away from your property reducing the hydrostatic pressure (water pressure), a compact two layer geocomposite membrane.
Geo-Drain Quattro – External waterproofing membrane, a compact 4 layer membrane system used vertically and/or horizontally.
Terraxx – A dimpled sheet with a geotextile layer which acts as a surface layer. Usually used as a green roof external drainage layer which also protects the primary waterproofing applied to substrate prior.
MS-Drain – Dimpled sheet with an integrated drainage layer. Simple and cost-efficient foundation for dry cellar walls. Improved performance, improved protection.
