Tanking membrane

Tanking membrane is a form of waterproofing where fully bonded waterproof materials 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 in combination with a cavity drainage system. If you are looking to waterproof a room, basement or cellar in your home, then contacting our specialist waterproofing surveyors will enable them to determine if installing tanking membrane will solve 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.

Where to use tanking membrane

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.

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. The basement waterproofing membrane mm thickness, mm stud depth, and density required will be assessed by our technical and structural waterproofing specialists

For the tanking membrane to be an effective barrier to water ingress and water damage, every precaution must be taken to ensure that the tanking membrane is carefully and completely sealed off.

The cavity drainage 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.

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.

Once applied, the wall can then be plastered or boarded over to easily begin renovating or decorating the room.

Benefits of our tanking membrane service

Choosing our waterproofing team to install your tanking membrane means that you will enjoy:

  • Protection against mould and damp problems in treated rooms
  • Wooden structures comprehensively defended from dry rot and wet rot
  • Application to affected walls provided by trained, qualified and experienced technicians
  • The peace of mind that comes from knowing the tanking membrane should remain effective for the lifespan of the property
  • The confidence that our long lasting guarantees provide

Perhaps the biggest advantage of using waterproof membranes is that they are not susceptible to cracking under the strain of external hydrostatic pressure. This is a common problem faced by traditional forms of wall waterproofing like cementitious tanking. Peter Cox often find ourselves recommending a structural waterproof membrane system when a cementitious tanking system fails.

Additionally, a structural waterproof membrane is unlikely to be affected by vibrations from nearby roads, railways or undergrounds.

If you are planning to convert a domestic basement or cellar to function as a new room in the home, waterproofing membranes can have plaster applied directly onto them or be dry lined. This means the waterproofing systems protecting your basement are completely integrated into your domestic fixtures and fittings.
