Geo-Drain Quattro is a unique drainage protection system/external waterproofing membrane that works in conjunction with Type A External Waterproofing or can simply be used in civil engineering situations. Geo-Drain Quattro is a compact 4-layer membrane which can be used vertically and/or horizontally.
Geo-Drain Quattro offers maximum safety for thick viscoelastic coatings and a multitude of alternate Type A systems. This holds true even if driving rain can penetrate through an imperfectly installed upper edge trim. In a watertight system, such rainwater would exert hydrostatic pressure on the waterproof coating. However, the micro-perforated slip film which together with the additional filter cloth, acts as a backup drainage layer behind the dimpled sheet ensures that any water is drained off safely. In addition, the slip film prevents the transmission of movement to the waterproof coating.
Geo-Drain Quattro has a very high compression strength and acts as a protection layer over Type A Primary Waterproofing Systems and can be used in conjunction with Our Type A range of BBA products to provide a system.
Geo-Drain Quattro is the perfect solution for waterproofing:
