Ensuring a good tanking solution as part of effective waterproofing
If you’re about to create a basement space in your premises or are looking to remove damp issues in your present one, then an appropriate tanking system fitted by experienced professionals is a key part of ensuring good waterproofing.
What is tanking?
In a nutshell, it’s the application of a special coating to the inside of a basement to prevent water entering from the outside as it would otherwise do into spaces below ground level.
It effectively makes the basement watertight.
Waterproofing and tanking aren’t simply interchangeable terms; waterproofing covers the general measures taken to waterproof a cellar or basement that could include the installation of drainage, pumps and membranes along with tanking as a specific part of the overall waterproofing process.
What tanking is best?
This would depend on your basement and whether it’s being newly built or is an existing part of your premises; firstly, you’d need to consult with damp proofing experts preferably serving your immediate areas – so for those in certain parts of Essex tanking companies in London could be approached.
Once your damp proofing experts have examined the area, they’ll recommend the best type of tanking for your particular circumstances.
This often consists of using a cementitious waterproofing system consisting of a cement membrane being applied to the basement walls and ceiling. This is classed as a ‘Type A’ tanking method as it provides a barrier to water but doesn’t physically remove it.
Alternatively, a cavity drain system may be used to direct water away from the area and controlling water entry using fitted membranes to route the water away.
You should insist on a tanking solution that meets BS8102 standards; this is your reassurance it’s an installation that meets the accepted industry standards laid down by the British Standards Institute Code of Practice for below ground structures.
Indeed, if you’re having a new basement installed, the BS8102 standard highly recommends that a waterproofing expert should be involved in the design stage along with the architect, builder and engineer.
Also, seek an installer who is prepared to look ahead and develop a treatment plan that will continue to protect your premises’ basement from damp in the future – structurally things can change over time, so having damp proofing experts monitor the situation will help prevent problems in the future.
Tanking is vital
A sound tanking arrangement in conjunction with appropriate and thorough waterproofing is key to keeping a basement dry; they’re susceptible to water ingress if not treated as brickwork naturally absorbs water from the outside and effectively ‘wicks’ it into the interior.
Basements are constantly in contact with possibly permanently damp earth, and water risks are heightened in areas of poor drainage and a high-water table.
If left untreated, or incomplete waterproofing is undertaken, significant structural damage can result after a while – not to mention the unpleasant conditions caused by damp environments and the difficulty of using the space in any practical sense if damp is present.
Your individual solution
Asking experienced damp proofing experts to come and help means you’ll ensure the right tanking system for your premises is installed; look for one who is keen to assess your situation individually as no two tanking and waterproofing requirements are always the same.
