Damp Proof and Waterproof Membrane for Walls.

Delta PT is a waterproof and vapour proof cavity membrane used for basement waterproofing. Cavity drainage membranes are Type C waterproofing.

Delta PT incorporates a thermally bonded mesh or lath on the surface that allows for the direct application of renders or boarding using dot and dab fixings.

Delta PT is typically used to waterproof basement walls and the retaining walls of lightwells.

This premium quality waterproof membrane has an 8mm stud to deal effectively water ingress and provide a high capacity drainage void.

Delta PT comes in a 40m2 roll making it great value for basement waterproofing projects.

  1. Sam – SB Build – Basement Contractor

    We use this to waterproof the walls of basement lightwells on our projects, easy and quick to use. Use with the fleece tape over the joints to prevent cracking of render.

  2. Sarah

    Used this membrane to damp proof a leaking basemen wall- Worked really well, a previous contractor has used a render that had cracked and leaked but this membrane sorted the issue no problems
