The vapour barrier and bitumen-based membrane can help to reduce damp in the cellar, which will help to keep your tanking costs down.

The Types Of Cellar Tanking Cost You Can Expect
There are three main types of tanking costs to factor into how much tanking costs for your basement. They are:
Injection Damp Proofing – Drilling holes in the walls and injecting them with a silicone-based external waterproofing solution is the technique of injection damp proofing. The solution uses capillary action to quickly penetrate the brick. Damp-proof injections typically cost less because they don’t have to be applied equally across the wall.
Therefore, for a house which is semi-detached, you could expect a cost of around £2000 for injectable damp proofing the basement or cellar floor. In order to drill holes into the walls, the contractor must first remove the plasterboard and wood which can increase the cost.
External Tanking – You can expect to pay around £35-£45 as a starting price per square metre for external tanking.
Internal Tanking – Tanking the internal walls of your cellar or basement will cost you slightly more than tanking the external walls. This is generally because there is a higher standard of finish so that your interior walls of that additional living space look nice. Therefore, you can expect to pay around £40-£80 per square metre.
