Tanking
"Get the very best in tanking for your wetroom from On the Level. 25 years of experience ensure your shower enclosure will never leak, providing years of pleasure."
There is no question that any wet room needs to be properly tanked. While it is important that all walk in shower spaces need to be waterproofed, nowhere is this more crucial than in a wetroom, where the entire shower floor should be sealed or 'tanked' in order to guard against leaks. If you're looking into the possibility of tanking and wet room installation, you've come to the right place.
The OTL tanking system is a liquid applied system that, once cured, creates a flexible membrane. As it is water based, it is non-sticky and is easily applied with a paint brush or roller.
Scroll down for a step-by-step guide on how to use our complete shower tanking kit, which features a liquid rubber technique that can tank even the largest of wet rooms. You can trust On the Level to ensure you have the very best in shower room tanking, providing years of showering pleasure for you and your family - without the risk of leakage.
The tanking kit contains everything to get you to tiling stage and has enough liquid
rubber to cover 12 sqms.
