Triton TM20 Cavity Drain Membrane 40m²

Triton TM20 Floor Membrane

Triton TM20 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 Triton TM20 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.

Triton TM20 floor membrane is manufactured from black high-density polyethylene (HDPE). It is impermeable to water, water vapour, Radon gas. It is also resistant to the chemicals and materials commonly used in building construction.

When Triton TM20 is used as a damp proofing or waterproof membrane, it may be installed independent of the moisture content in the underlying concrete construction. Any water running over the substrate has de-pressurized into the air gap under 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.
