Delta provides a range of products for drainage, structural waterproofing and underground wall and floor protection. Cost effective, simple to install, DELTA® membranes keep hydrostatic pressure away from walls, ceilings and floors keeping living spaces dry and insulated.
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® products are used for foundation-wall protection, drainage, and waterproofing. They are suitable for a wide range of building and rehabilitation applications.
The company's product range includes a variety of damp / waterproof membranes and accessories for all applications.
Made of a special type of polyethylene, DELTA® membranes form highly efficient seepage and drainage layers. They are compression-resistant, maintaining their outstanding hydraulic properties even under heavy and permanent loads.
The fused-on geotextile layer of the multi-layered DELTA® dimpled sheets filters soil particles out of the seepage water, thus preventing the air gap from becoming clogged up. With a welded-on plaster mesh, dimpled sheets may be used as backing for shotcrete and mortar.
DELTA® membranes are rot-proof, resisting saline solutions, inorganic acids, alkalines, and polar liquids. They are proof against attack or modification by any of the minerals, humic acids, and bacterial catabolic products that naturally occur in the soil, as well as by bacteria, fungi, and micro-organisms.
The response of all sheet types to soil or underground water is completely neutral, nor will they leach any harmful and / or ecologically doubtful substances. Care should be taken to ensure that they are not permanently exposed to UV radiation.
