Wet Room Waterproofing / Tanking

The key to the life and success of any wet room or walk in shower is sound preparation and waterproofing of the floor and walls that will come into contact with the water.

Waterproofing of the floor (and walls) is acheived by using a tanking kit. There are two main types available:

a) Liquid Tanking such as PCI Lastogum or Weber Sys Protec. - These are a paint on solution that contain primer, sealing tap (for joins etc) and a liquid soloutin that requires no mixing and is painted on wit a roller. Suitable for both the waterproofing of floors and walls. Safe to use in conjunction with underfloor heating.

b) Membrane Tanking such as Impey TileSafe and Impey Waterguard. These are physical membranes that are laid onto of the floor before tiling. Whilst suitable for use with underfloor heating, maximum wattage limits such be observed were specified. Although particularly suited to floor applications Tilesafe can also be applied to walls as an additional precaution.  However, there is a maximum weight limit.
