Platon P20 is a high capacity drainage membrane recommended for use on all floor applications below ground, due to its ability to control free flowing water.
Platon P20 Membrane is manufactured from black high-density polyethylene (HDPE). It is impermeable to water, water vapour, Radon gas and is resistant to the chemicals and materials commonly used in building construction.
When P20 is used as a damp-proof 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 the one face of the membrane. The studs are spaced at approximately 60mm centres and are 20mm deep.
High capacity P20 is recommended for use on all floor applications below ground due to its ability to deal with and isolate running water. The deep stud profile is designed to provide a large water capacity per square metre and thus resist potential blockages caused by lime deposits. Anti-Lime Coatings must be used as a dressing on concrete or concrete filled blockwork.
In accordance with NBS Specification J40 (clause 290) – Flexible Sheet Tanking/Damp Proofing.
