Platon P20

Heavy duty drainage membrane

Platon P20 is a 20 mm studded cavity drain membrane manufactured from high density polyethylene.

It is impermeable and resistant to moisture and most chemicals used in construction.

It allows floor coverings to be installed independent of the moisture content of the underlying structure, and running water to travel in the air gap to suitable drainage, without creating any pressure.

Platon P20 can be screeded or receive a dry board finish. When using a dry board the studs must be filled, so that the load is transferred to the underlying structure.
