What is Cellar Tanking?

Cellar tanking refers to the process of applying a waterproofing solution to a basement or cellar. It’s important to stop water ingress in properties with basements below ground level. These basements are vulnerable to water coming from the surrounding soil. Tanking systems come in different types. These include cementitious coatings, liquid rubber membranes, and self-healing systems. Each one helps keep your basement or cellar dry and liveable.

Without an effective cellar tanking system, basements can get damp. This can cause structural damage, mould growth, and health issues for those living there. Cellar tanking is essential. It helps maintain the property’s value and ensures its residents’ safety and well-being. If you’re planning a cellar tanking project, it’s necessary to understand the legal requirements that may apply.
