Wykamol CM20 High Capacity Waterproofing Membrane is for use on walls, floors, vaults and tunnels with minimal surface preparation required. Also suitable for external foundation waterproofing and internal above ground waterproofing to provide insulated dry lining where conventional plaster finishes are not suitable.
Wykamol CM20 Waterproofing Membrane is BBA-approved as suitable for type 'C' Cavity Drain Membrane Systems in accordance with BS8102 and now includes our high-vis yellow membrane.
This waterproofing membrane is the highest drainage capacity membrane in the CM range, giving a void of 14 litres/m². Suitable for use on floors and walls in very wet situations, or where a large stud height is needed to maximise insulation values.
This membrane is available in 2 m width as 20 m rolls or 10 m rolls, the latter being light enough for individual manual handling.
CM20 creates a dry, habitable living space in areas previously suffering from damp or wet conditions.
