Wet Room Tanking  

Wet Room Tanking

Aquaproof wet room tanking system has been specifically designed to prevent leakages from tiled wet room areas. The product is CE approved and has a 10 year manufacturers guarantee.

By specifying Aquaproof Wet room Tanking with the CE mark, you can ensure your tanking is fit for purpose and has been rigorously tested to the highest standards.

Aquaproof Wet Room Tanking is the complete answer to under tile wet room waterproofing:

  • Fully waterproof
  • Breathable (water vapour permeable)
  • Flexible system
  • Reinforcing tape at all joints/ pipe entries
  • Simple application
  • Creates a perfect surface for tiling with standard waterproof tile adhesives
  • Compatible with under floor heating
  • User friendly (virtually odour free)

Aquaproof Waterproofing Tanking System is suitable for application onto wooden sheeting, MDF, plasterboard and most commonly used construction boards including Wedi. The product is designed to be flexible, resisting normal thermal movement in the room, and does not become brittle with age.

The Aquaproof Tanking System is suitable for use in a wide number of situations. It is frequently specified for use under traditional shower trays, in bathrooms, kitchens, and toilets: basically anywhere where there is a danger of leakage from wet areas.

Many hotels and apartment blocks have used the system to protect the building from leakages onto lower floors.

Aquaproof can be purchased as kits or separate products.

We have provided you with a Wetroom Wate​rproofing Material Calculations Guide to help you make sure you are purchasing the correct amount of materials for the size of wet room you are installing.

Take a look at our installation sequence to see just how easy Aquaproof is to apply.
