When the product acts as a damp proof membrane, both the product and floor coverings may be installed independent of the moisture content in the underlying concrete construction and with running water not under pressure in the air gap.

Studs are formed in a regular pattern on the one face of the Membrane. The studs are spaced at approx. 60mm centres. The product is supplied in rolls 2m x 20m.
