What’s The Difference In Tanking And Waterproofing?
Good question: what exactly is the difference between tanking and waterproofing your basement? We get asked this a lot. In very simple terms, “tanking” is a type of basement waterproofing. “Waterproofing” refers to a variety of methods, and tanking is one of these.
Tanking is also known as “Type A waterproofing system”. It involves coating the walls and floor with a waterproof cement or slurry, creating a barrier that prevents water ingress. It’s a cheaper option, and can cost as little as £40 per square metre.
However, tanking isn’t always the right solution. “Type C” is a more structural approach to waterproofing. This is a more active way of managing water ingress, using a drainage system and a sump pump. Water is actually taken away from the property, rather than simply halted by a membrane.
Naturally, this structural work is more expensive than tanking, but is essential in certain conditions, and may be a requirement for planning permission. If you want a belt-and-braces approach, you can have both options working together.
