Basement Waterproofing Membranes

Our range of membranes are manufactured with air gap technology, they consist of a high-density polyethylene (HDPE) sheet, molded into a series of raised studs, or dimples. When the membrane is applied to the substrate the studs create an air gap cavity. This cavity allows the substrate to breathe and any water/water vapour that seeps through the substrate meets the membrane and is drained to a suitable drainage system. This cavity neutralizes the hydrostatic pressure (groundwater pressure), manages and controls the flow of groundwater and also has thermal qualities.

Our cavity drain membranes 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 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.
