Description

CM20 Waterproofing Membrane

Wykamol CM20 membrane is the highest drainage capacity membrane in the Wykamol range giving a void volume of 14 litres/m². Suitable for use on the floors and walls in very wet situations or where the large stud height is desired to maximise insulations values. When overlaid with concrete, the large diameter studs will give high point load resistance capabilities (180kN/m²) to support load-bearing walls built off the slab.

Fixing

Starting at one side of the room, unroll the membrane with the studs down and cut to fit the room as one would when fitting a carpet. The next membrane width is rolled out so that the flanged edge overlaps onto the edge of the previous roll of membrane. Clean both edges. Wykamol tape is then applied to the high flat area between the first two studs at the edge of the previous roll of membrane with the backing paper still intact. Check the two widths for alignment, with the flange covering the backing paper. Starting from the end of the joint, remove the backing paper and press down on the joint, sealing the two sections together.
