We are frequently asked the difference between tanking and waterproofing. This is a common question for people who are looking to convert a basement or cellar into a dry space. Basement waterproofing typically refers to all types of waterproofing system (barrier, integral and drained waterproofing). Basement tanking describes the application of one type of coating or membrane (barrier protection). We provide products for all types of waterproofing, and often recommend that systems are combined for optimum protection against water.
What is Basement Waterproofing?
Basement Waterproofing is the general term for all methods of waterproofing used to keep basements or cellars dry. This includes the installation of a ‘Type C’ Cavity Drain System. This system manages water seeping into the property and moves it safely away to a pump or safe drainage.
What is Basement Tanking?
Basement Tanking is the application of a membrane or coating to the inside or the outside of the structure. This stops water entering the habitable space of the property thus making the basement watertight. Within the waterproofing industry this is defined as ‘Type A’ waterproofing.
Does tanking stop rising damp?
A ‘Type C’ Cavity Drain System is the most effective way to stop rising damp. The combination of materials and systems used, maximises the waterproofing capacity to create a dry interior space. Tanking alone can stop rising damp but it’s important to have your property checked by a professional before undertaking any damp proofing work. They will be able to advise you on the extent of your damp problems and offer solutions for the best way to prevent any further water damage and to keep the interior of your property permanently dry.
What Are the Options For Tanking and Waterproofing an Existing Property?
- Option 1 – Cavity Drain System – comprising waterproof membranes, drainage, pumping and control systems. These systems manage water entering the property and safely remove it.
- Option 2 – Tanking Membrane, Coating or Slurry to hold back the ground water from entering the building.
- Option 3 – A combination of the two for maximum protection. This should be considered if the structure is very porous and so at risk of allowing too much water to enter for the Cavity Drain System to deal with. In all cases, the flow of water should be stemmed as much as possible.
