Delta membranes

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 air gaps 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, and they do not leach any harmful or ecologically doubtful substances.
