Frequently Asked Questions
What is floor tanking?
Floor tanking is the process of applying a waterproof membrane system to a wet room floor before tiling. It creates a continuous waterproof layer beneath the tiles that prevents water from penetrating the subfloor and structure. It is an essential stage in any wet room installation and must be done correctly to prevent costly water damage.
What area does this kit cover?
This kit covers up to 5m² of floor area. For a typical wet room, measure the floor area (length × width in metres) to confirm this kit is sufficient. Call us on 01603 381095 if you need advice on coverage for your specific installation.
Why are internal corners included?
Internal corners — where the floor meets the wall — are the most vulnerable points in a wet room waterproofing system. The 4 pre-formed internal corners included in this kit create a reliable, consistent seal at these critical junctions.
Is professional installation required?
Professional installation is strongly recommended. Wet room tanking is a critical waterproofing stage — incorrect application, particularly at joints, corners, and pipe penetrations, can result in water damage to the subfloor and building structure.
