Damp-proof membranes

Delta Membrane Systems

Delta Membrane Systems specialises in the manufacture and installation of waterproof membranes, providing a solution for insulating and isolating damp areas.

Delta® products can easily deal with aggressive ground-water conditions. Other applications include turf-covered roofs, barn conversions and tunnel linings.

Delta®-PT is a high-performance polyethylene membrane that offers a watertight, temperature- and chemical-resistant seal.

Delta®-Lath membrane has a mesh incorporated on the internal face, attached by a thermic welding process in manufacture. This allows for direct render, plasters or DAB-fixed plasterboard.

Delta®-FM is designed for floor applications. It is manufactured using high-performance, high-density polyethylene, with a low-stud profile.

Delta® membrane systems can be used externally as a waterproof support for rendered finishes, especially in exposed situations.

Delta® render can also be applied to give a decorative finish which will not require painting.

Delta® membrane systems are installed by specialist contractors, supplied with a 30 year product guarantee and certified to BS EN ISO 9001.
