Wykamol CM20 High Capacity Waterproofing Membrane 40m²

Wykamol CM20 High Capacity Waterproofing Membrane (formerly Triton TM20 Cavity Drain Membrane 40m²) is a high capacity drainage membrane recommended for use on all floor applications below ground, due to its ability to control free-flowing water.

With a high drainage capacity, Wykamol CM20 is ideal for basement floors. The deep stud profile is designed to provide a large water capacity per square metre. This minimises potential blockages caused by lime deposits. Anti-Lime Coatings must be used as a dressing on concrete or concrete-filled blockwork.

Wykamol CM20 floor membrane is manufactured from black high-density polyethylene (HDPE). It is impermeable to water, water vapour and Radon gas. It is also resistant to the chemicals and materials commonly used in building construction.

When Wykamol CM20 is used as a damp proofing or waterproof membrane, it may be installed independently of the moisture content in the underlying concrete construction. Any water running over the substrate is depressurised into the air gap beneath the membrane. Studs are formed in a regular pattern on one face of the membrane. The studs are spaced at approximately 60mm centres and are 20mm deep.

Specification: In accordance with NBS Specification J40 (clause 290) – Flexible Sheet Tanking/Damp Proofing.
