Turning unused dingy, water damaged or even flooded basements into warm, inviting, usable living space can be easily achieved with our structural waterproofing materials which include drainage, sump pumps and membranes. Cost effective, simple 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 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.
