Cavity Drain Membranes

In Basement construction or refurbishment, cavity drain membranes provide an alternative to conventional cementitious tanking systems, which work by holding the water back. Internal cavity drain membranes work on the principal of allowing water to continue to penetrate the structure but control it in the air gap and divert it to a suitable drainage point. They do not allow pressure to build up against the internal construction and the air gap behind the membrane allows the structure to breathe and to extent to dry out. The membranes are loose laid on floors and fixed to walls using special plugs and sealing materials, with little or no preparation required to the substrate. Once the membrane has been fitted, wall surfaces can be screeded or a floating dry board system installed. External cavity drain membranes provide a drainage and protective layer to the primary waterproofing system.

Platon Plaster Mesh

Platon Plaster Mesh is a double layered cavity drain membrane comprising a studded HDPE layer bonded to an 'HDPE twist' mesh layer which forms a key for most common plasters and renders. As with other Platon membranes, Platon Mesh can be fixed directly to existing wall finishes without the need for extensive hacking off or preparation.

 

 

 

  • HDPE membrane with integrated mesh layer for direct plastering
  • For internal application on walls above or below ground level
  • Compatible with other Platon membranes

 

Specification

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

 

Platon P5

P5 is a tough and economical membrane for both remedial and new build construction. It is suitable for sub-ground tanking and also for use above ground to isolate walls which are damp or contaminated with salts. P5 can be dry lines on walls and screeded or a floating dry board system fitted on floors.

  • Economical 5mm HDPE cavity drain membrane
  • Suitable for both walls and floors, above or below ground
  • Impermeable to water, gas or water vapour
  • Compatible with other Platon membranes

Specification

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

Platon Plaster Base

Platon Plaster Base can be installed on internal walls and vaulted ceilings above or below ground level. The substrate remains visible through the clean membrane for precise fixing. It is suitable for use with sand and cement renders and most lightweight and renovating plasters.

  • BBA approved
  • HDPE cavity drain membrane for direct plastering
  • Single component, no mesh or fabric layer
  • Unique undercut stud design creates mechanical key plaster
  • Easy to cut, fix and seat
  • Impermeable to water, gas and water vapour

Platon P20

 

 

 

 

 

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. The deep stud profile is designed to resist blockages caused by time deposits.

  • BBA approved
  • Heavy duty, deep studded HDPE cavity drain membrane
  • Principally used on floors
  • For areas subject to high volume water penetration
  • Impermeable to water, gas and water vapour
