Tanking membrane

Tanking membrane is a form of waterproofing where sheets of water-proof material are applied to walls and floors either above or below ground in order to prevent water ingress.

Tanking membrane is most commonly used to either protect properties against penetrating damp, or as part of a cavity drainage system. If your home or basement is suffering from damp problems then contacting our specialist waterproofing surveyors will allow them to determine whether installing tanking membrane will resolve the issue and clear up your damp problems.

When to use tanking membrane

Leaking basements and cellars are prime candidates for tanking membrane solutions. Once the membrane has been fixed to the wall then it will remain in place effectively keeping out water for the remaining lifespan of the property, as long as it is not disturbed or punctured by drilling or attaching fixings to the wall. Tanking membrane can easily be plastered or boarded over allowing you to renovate your now dry basement or cellar in any way you wish.

Furthermore, tanking membranes is also an extremely useful way to combat penetrating damp and eliminate related problems like mould and wood rot in rooms where a large build up of water is expected, such as wet rooms, bathrooms and kitchens.

How does tanking membrane work?

The water-proof sheets of tanking membranes are made out of high performance polyethylene or polypropylene. These materials not only resist water ingress, but are also resistant to chemicals and temperature extremes meaning that, once installed, the membrane will retain its efficacy allowing you to forget about your damp problems.

The sheet is formed with a series of studs which are designed to create a continuous air gap behind the membrane and to provide a channel for water removal to a drainage system under the floor.

Tanking membrane installation

Once our technicians prepare the surface by removing old damp affected plaster and salts, then they can begin cutting the sheets of membrane to size.

In order for the tanking membrane to be effective, it is absolutely essential that every precaution is taken to ensure that the tanking membrane is carefully sealed off and all joints are completely sealed.

The membrane is fixed to the wall using plaster plugs. If the wall is below ground or contains moisture then we will use seals to ensure there can be no water ingress around the plug.
Once applied, the wall can then be plastered or boarded over to easily begin renovating or decorating the room.

If the membrane is being installed as part of a cavity wall drainage system then we will also install suitable drainage channels around the perimeter of the room to ensure that any water is filtered out of the property.
