Waterproof tanking is the process of applying a waterproof barrier to walls and floors before tiling in wet areas such as showers, wet rooms, and bathrooms. It creates a completely sealed surface that prevents water from passing through grout and tile into the underlying building structure. Without tanking, water can seep behind tiles over time and cause serious damp, mould, and structural damage. It is considered an essential step in any professional bathroom or shower installation in the UK.
Tanking and waterproofing are closely related but not exactly the same thing. Tanking specifically refers to creating a fully sealed, watertight barrier on walls and floors using membranes, slurries, or liquid coatings. Waterproofing is a broader term that covers any method used to prevent water ingress, including tanking, damp proofing, and cavity membrane systems. In bathroom and shower contexts, tanking is the most commonly used form of waterproofing in the UK.
Yes, tanking a shower before tiling is strongly recommended and considered best practice in the UK. Tiles and grout alone are not fully waterproof, and water can penetrate through grout lines and cause serious damage to the structure behind the tiles over time. A proper tanking system involving a liquid membrane, sealing tape for corners, and a primer should be applied and allowed to fully dry before any tiling begins. Skipping this step is one of the most common and costly mistakes made during bathroom renovations.
A professionally applied bathroom tanking system can last anywhere from 10 to 25 years or more when installed correctly. The longevity depends on the quality of the tanking product used, the standard of application, and how well the bathroom is maintained over time. Premium liquid membranes and cementitious tanking slurries from trusted brands tend to offer the best long-term performance. Regular resealing of grout lines and silicone joints helps extend the life of the overall waterproofing system.
Yes, tanking is one of the most effective methods for stopping damp in bathrooms and wet rooms. By creating an impermeable barrier on walls and floors, it prevents moisture from penetrating through to the building structure underneath. It is particularly important in shower enclosures where walls are exposed to large volumes of water on a daily basis. For basements or areas with rising damp, a specialist tanking system such as a cementitious slurry or cavity membrane may be required for best results.
The best tanking kits for showers in the UK include well-known brands such as Mapei, Mira, Sika Aquaseal, and Everbuild. A good tanking kit should include a liquid waterproofing membrane, sealing tape for corners and joints, and a primer for surface preparation. The kit should be applied in at least two coats, allowing adequate drying time between each coat before tiling. Always choose a product that is specifically designed for wet room and shower use to ensure full waterproof protection.
