Delta Membranes Systems

DELTA provide the world’s foremost range of products for structural waterproofing and underground wall and floor protection as well as water management drainage & sump pumps.

Cost effective, easy to install, DELTA® membranes keep hydrostatic pressure away from walls, ceilings and floors keeping living spaces dry and insulated.

Our systems can be used on domestic as well as 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 membranes themselves. 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.

The membranes are manufactured in Herdecke, Germany under full quality and environmental assurance schemes. The system has full professional legislative approvals in all countries in which it is used. But the innovative world class design and top quality manufacturing and materials are only the start. We provide a complete design, training and report service to ensure our products are always used to their maximum potential. We’re a one stop shop right from the design stage to on site visits with recommended installers that can provide the necessary warranties and guarantees.
