Tanking is a cementitious form of basement waterproofing that has been applied to basements, cellars and other underground spaces for decades.
Tanking was developed to hold back hydrostatic pressure from the earth surrounding the basement level of a property. Without tanking, underground walls would often crack or leak.
For more information about the best tanking system for you, or how to waterproof your basement simply fill out our enquiry form below.
The basic principle of tanking involves the application of a waterproof cement or slurry to the basement walls. The tanking will ultimately provide a smooth concrete wall surface, which is aesthetically pleasing and provides protection from moisture ingress and subsequent damp problems.
For tanking to work it must be applied to stable, undamaged walls. There also has to be exceptional attention paid to weak points in the space, such as the wall to floor joint. When a qualified team has applied a professional tanking installation, it should be watertight and leave you with a dry space ready for practical use.
Cementitious tanking systems are often referred to as “Type A” waterproofing systems. Type A is an industry term that comes from BS8102 (the British Standards Institute’s recommendations for structural waterproofing). It basically means that this form of waterproofing creates a barrier to moisture ingress but does not actively remove any water.
There are occasions when tanking is not the appropriate solution. Tanking is susceptible to cracking and failing in the following circumstances:
If tanking is not an option, or your current tanking has failed due to reasons above, then there are other basement waterproofing methods that could be a better fit.
