Here is another question asked by a member of the public relating to timber treatment. We hope that it and the answer, which we include below, are useful.

Could you tell me what the best option would be to treat rising damp in an > old solid stone wall house, and how would I calculate how much product to order.

Here's our answer:

The best way is to use Envirosafe Injection Cream. Calculate using the information on the product technical datasheet on the website with regard to wall width but I've included a screenshot of the application information below to save you time.

For Large thickness walls you might consider tanking as an alternative as it may be difficult to get a continuous band if the walls are random. Go to our website and look for Tanking Slurry.
