Wetroom waterproofing

Wetrooms are a critical area in terms of waterproofing.  Escaping water can lead to severe damage in other areas of the building. Discoloration of decorative finishes, leakages into adjoining rooms and tiles coming loose are often the first visible signs of a problem, but at this stage a large amount of "behind the scenes" damage has already occured.  If such rooms are waterproofed (tanked) correctly from the start the building is protected and the wetroom enjoyed without problems.  The wetroom is waterproofed seamlessly from the walls to the floor to the gully. The waterproofing layer is temperature stable and able to bridge possible cracks.
