Delta Sytems incorporating DELTA® membranes to keep hydrostatic pressure away from walls, ceilings and floors keeping living spaces dry and insulated.
Delta systems can be used on domestic and/or commercial properties from small scale basement conversions to major public works, such as the London Underground. The channel tunnel for example claims over 70,000m² of DELTA®-MS.
DELTA Systems can easily deal with aggressive ground water conditions, where basements are liable to flooding, or indeed where simple dampness, contamination or salting problems are prevalent.
The main components of the system are the membranesthemselves. These are manufactured from virgin HDPE which is thermally alkaline stabilised. The stud heights vary between 3mm for DELTA®-FM, 8 mm for DELTA® MS 500 & DELTA® PT-Lath to 20 mm for DELTA® MS 20. The cavity created by the membrane contains between 5 and 10 Litres of space respectively. This is known as either the “Air gap” or the “Drained Cavity”, in wet situations. The cavity drain system forms a waterproof inner lining to the walls and floor whereby the water or dampness is collected and managed via a sump/pump station.
