Sealing Concrete Floor-Wall Joints

[Jazzer]

Hi!

We have an ongoing issue with moisture low down in parts of internal walls and have been advised that the solution is to form deep seal
floor joints/fillets.

Does anyone have any experience of this, or know of someone who would be able to advise and do the job?

Any help would be greatly appreciated.

Anyone??

It’s a 1950s house with concrete floors and solid walls. There is low-level moisture on parts of internal walls (rooms either side).
The DPC is being bypassed, so walll-floor joints and plastering are being looked at.

The chemical DPC treatments (nite the plural) did nothing. The DPC is present, but is being bridged. We’re looking to remove plaster to expose the DPC , and seal floor-wall joints.
It’s this latter aspect that we need advice and direction on…..it’s hard finding someone with experience of this who can do the job!

Thank you for taking the time to reply in such detail, you know stuff!!

We will remove plaster to above DPC level, just below the height of the taller skirting, to allow moisture to evaporate better,, as well as sealing the joints.

This should work!

This makes a lot of sense, we’ll give it a go for sure!👍

I would rather have someone who knows what they’re doing do the work, and would happily pay.

I’d never again employ the usual cowboys, who just want o inject and cover up problems for a few months, without taking time to establish what the underlying cause is.

We’re based in Essex, so if you know or can recommend someone, please let me know.

Thank you for these very helpful replies.
