Hi all,
I have a victorian mid terrace built 1890 with a basement. One wall is below ground and is very damp with also floor very damp.
Other walls are adjacent to neighbouring properties or are lower ground and go out to a garden. These have some signs of damp too but not as bad as the wall that is below ground.
I plan to lower the basement by about a foot and lay new floor slabs and damp proof to make livable plus install a PIV.
I’ve had a couple of quotes, both from experienced basement specialists who seem professional and knowledgable.
One has said simply that they would apply type C solution all round and drain it to a man hole outside the door to the garden, says you won’t go wrong with that solution.
One has spent more time examining the walls and what is surrounding them and has suggested the same
solution in the underground walls and adjoining walls, but thinks a chemical DPC to varying heights, horizontal or vertical would be sufficient in other walls with a small area requiring salt retardant render. They’ve also recommended horizontal DPC as well as cavity membrane on some walls. (Wasn’t sure what you needed both?)
Any thoughts on what would be the preferred option if cost was no object to make the space liveable?
Was a bit concerned that type C all round was overkill but also concerned that DPC isn’t highly regarded and doesn’t let the walls breath sufficiently.
Thanks in advance
