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. Unlike a shower tray, a wet room has a tiled floor with no physical barrier — the waterproofing is built into the floor construction itself. Tanking 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. For larger wet rooms, additional kits or a larger coverage option may be required. Call us on 01603 381095 if you need advice on coverage for your specific installation.
What is included in this kit?
The kit includes the Swan By Impey Waterbarrier waterproof membrane (sufficient for 5m²), 4 pre-formed internal corners for sealing floor-to-wall junctions, and joint tape sufficient for all membrane joints within the kit coverage area. Installation instructions and guarantee documentation are also included.
Why are internal corners included?
Internal corners — where the floor meets the wall — are the most vulnerable points in a wet room waterproofing system. Water pressure and building movement concentrate at these junctions, making them the most likely points of failure if not correctly sealed. The 4 pre-formed internal corners included in this kit are specifically designed to create a reliable, consistent seal at these critical junctions, removing the need to cut and fold the membrane by hand.
Is this kit suitable for timber subfloors?
Swan By Impey Waterbarrier products are designed for use on a range of subfloor types. Please refer to the Swan By Impey installation guide supplied with the kit to confirm suitability for your specific subfloor. If you are unsure, call us on 01603 381095 and we can advise.
What guarantee does this kit come with?
The Swan By Impey Waterbarrier floor tanking kit carries a 10-year guarantee, covering the waterproofing performance of the system when installed in accordance with Swan By Impey’s installation guidelines.
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. The 10-year guarantee may be conditional on correct installation in accordance with Swan By Impey’s guidelines.
