Delta Geodrain Quattro

Structures that are earth retaining can be damaged by moisture penetration from the outside or by water under hydrostatic pressure. DELTA® Membranes are available as geocomposites to deal with such problems. They act as a waterproof drainage layer, and quickly remove the water to suitable drainage around the structure. They prevent the build up of hydrostatic pressure on the structure and filter the water via an internal polypropylene filter layer. Compact 4 layer composite membrane used externally, vertically and horizontally. The Geo-Drain Quattro has a very high compression strength, and acts as a protection layer over flexible waterproofing. It can be used up to depths of 10 metres.

DELTA®-GEO DRAIN Quattro can also be applied over the primary external waterproofing layer on certain types of structure, prior to back filling. The membrane is only fixed along the top edge every half a metre with our Geo-Drain Clips, and the flange on the edge of the roll is used to lap onto the next section and is sealed using the pre applied adhesive tape.
