The DELTA® PT-Lath high performance polyethylene meshed membrane is used for above and below ground waterproofing and damp-proofing internal and external walls, vaulted ceilings. It can be used in new constructions or in existing buildings over a contaminated or damp background.

The membrane is extruded into a series of studs which create a continuous air gap behind the waterproof membrane. On the face of the membrane a welded mesh allows plasters and renders to bond efficiently to achieve dry and durable finishes.

DELTA® PT-Lath is watertight, resistant to high and low temperature extremes, chemically resistant to acids, alkalis, oil and solvents and is approved for use in drinking water applications. 

It can support plastering, rendering or a dry lining fixed by plaster dabs (where appropriate) in the following situations:

  • On damp walls in underground situations subject to high groundwater levels, and perennial moisture
  • On vaulted ceilings of archways or cellars subject to water ingress
  • In conjunction with a remedial dpc system where the walls have a high salt content, and / or it is necessary to complete the installation immediately without allowing a period for initial drying
  • Over walls which have a friable or painted surface, are contaminated with oil or mould, or have a high salt content
  • As a waterproofing membrane in areas subject to vibration

Other uses (depending on the application required and site conditions)

  • A dry lining for walls, ventilated into the room via aeration slots at the top and bottom of the wall or via passive air vents, where access through an external wall is available
  • A sealed system covering wall, floor and ceiling with provision made for disposing of water build-up behind the membrane via a sump and pump.

Tape and fixing

PT Plugs can be used to fix DELTA® PT-Lath to walls, with grommets and double-sided tape for sealing at joints/overlaps. Fleece tape can also be used for over-sealing joints like such as the wall and floor joint. It has a fleece backing designed for plastering and rendering onto.
