Damp Proof Membranes

A Damp Proof Membrane is a waterproof layer that prevents the transfer of moisture between different areas of buildings. When a Damp Proof Membrane is installed into a building structure, it acts as a physical Damp Proof Course by preventing damp from entering the building through the walls or floors. For this reason, Damp Proof Membranes are excellent systems that are used to protect basements and cellar conversions from the ingress of water and damp. 

We have a range of Damp Proof Membranes, which come in different stud depths and sizes, kits and accessories for the installation of a dependable waterproofing system to your basement or cellar. If you are starting from scratch, have a look at our Damp Proof Membrane Kits, which have everything you need to install a Damp Proof Membrane at a great price.

  • Damp proof membrane rope



    You can use this rubber butyl rope to form watertight seals between plug fixings (used to secure damp proof membranes to building substrates) and the membranes, by wrapping a bead of the rope around the head of the plug prior to application. It can also be used for jointing membranes where the studs do not overlap and a flat flange to stud joint seal is not created, if a flat seal is possible damp proof membrane tape should be used instead. (10mm bead x 5m).

Installing Damp Proof Membranes

Waterproofing or Damp Proof Membranes can be a great way of stopping damp penetrating your property. The Damp Proof Membranes can be bought as part of kit which contains everything you need to damp proof your wall. Read below to see how easy it is to install a Damp Proof Membrane at your property.

Preparing the Wall for the Damp Proof Membrane

1. Remove or renew all contaminated and loose plaster and locate the sources of the moisture ingress.

2. Treat wall with masonry biocide solution to ensure wall is free of moulds and fungi.

3. If the wall is salting then treat with SkilledBuild AntiSalting Treatment.

Installing the Damp Proof Membrane

1. When installing a Damp Proof Membrane it is best practice to work outwards from the centre of the Damp Proof Membrane. The Damp Proof Membrane Plugs should be installed at spacings of 300mm centres both horizontally and vertically to create a diamond pattern.

2. Drill 8mm diameter holes through the Damp Proof Membrane into wall to a depth of 70mm, or length of Plug being used. 

3. Push the Plug Seal on to the Plug ready to be installed into the Damp Proof Membrane.

4. Push Plug through the Damp Proof Membrane into fixing hole until seal is compressed and the Damp Proof Membrane is fixed to the wall.

5. Use the Damp Proof Membrane Tape to seal the joints between the Damp Proof Membrane sheets to ensure the membrane is tightly sealed together. Damp Proof Membrane Rope is applied between overlapping strips of Damp Proof Membrane at edges.

6. It is advised to use Damp Proof Membrane Corner Tape to seal the joints at the wall and floor in order to achieve the best results.
