CM3 Cavity Drain Membrane is a 3 mm studded membrane, suitable for Type C waterproofing or damp-proofing of floors and walls, and delivering a grade 3 environment to BS8102:2009 and NHBC Chapter 5.4.
Wykamol CM3 Waterproofing Membrane is suitable for type 'C' (drained protection) structural concrete constructions in accordance with BS 8102.
When used for waterproofing basement floors and walls it is recommended that perimeter drainage channels are provided to optimise the flow of ground water towards the sump location.
Wykamol CM3 Waterproofing Membrane is used in a dry lining application. Various systems can be used in the head of the fixing plug, from timber battens to steel dry lining systems.
The Wykamol range of cavity drain membranes are high-quality, structural waterproofing materials, with a choice of stud height for different drainage capacities and applications.
