Damp Proofing

Damp proof course injected into internal walls of Victorian terrace property or remove concrete and reinstate suspended timber floors?

Anonymous user 28/02/2024 - 2.58 PM

We have recently bought a (potentially) lovely Victorian terrace. The house has a multitude of issues to address but one in particular is rising damp in the internal walls. None of the other houses in the terrace have rising damp or damp issues and all have the original suspended timber floors. However, the chap that we bought the house from was a a rather dodgy DIY-er, bought a concrete mixer and laid concrete all over the ground floor. I am told that this is what has caused the rising damp as the floor no longer breathes. We plan to knock down several of the internal walls (which have damp), so some rising damp would remain and my question is, are we better having DPC injected (which I'm told in some cases isn't very effective) or having the concrete removed and reinstating suspended timber floors (and air bricks if no longer present)? We would like to have underfloor heating under some form of wooden flooring if this affects our options? What would be the kind of difference in cost between these options also? Many thanks!

Are you a tradesperson and able to answer this question?

Without a shadow of a doubt, if your budget allows, rip up the solid floor and reinstate a timber suspended floor. I haven't seen the property but from your description you have been correctly informed with regards to why dampness is occurring in your internal walls.

Hi there, Difficult to answer without actually being able to look at the issues. I am sure it would be cheaper, and more practical to leave the floors in their present state. The walls can be injected with cream, but in addition you may want to look into having damp proof membranes installed onto the brickwork, or traditional sand and cement render applied to all the walls approximately one meter high. Obviously this involves taking this area back to bare brickwork, and then fixing plasterboard / skim once treated. Does the damp show on any of the concrete floor or is it restricted to the walls?

Removing the wooden floors and replacing the with concrete would not in itself create the damp however the damp proof membrane should have installed under the concrete coming up and to the wall if there's has not been done then yes it would Bridge the original damp course within the brickwork
