DPM advice

[myflatisdamp]

Hi,

My first post but have been reading the advice here for a few months, lots of knowledgeable people so hopefully I'll find the answer I'm looking for.

I've recently bought a basement flat which has a quite severe problem with damp. It's the basement flat in an early-Victorian townhouse (built 1820s). A lot of this is caused by simple things such as cracked external rendering and cracked steps up to ground floor entrance which are scheduled to be repaired by the freeholder shortly. The problem has also been exacerbated by the flat having been vacant for approx 18 months due to the previous leaseholder (a company) going bust.

I am in the process of obtaining quotes to treat the internal areas with either an injection and cementicious solution or a membrane, or a combination of the two.

Once this has been done I will be doing a full renovation of the flat (re-wire, new kitchen, bathroom, re-decorate) and so I want to ensure that the damp doesn't come back to haunt me in future and so I am contemplating treating the floor too.

At the moment I am considering using a liquid DPM (such as F. Ball Stopgap F76) and then laying a product such as Oldroyd Slimline.

Is this a suitable combination?

Thanks in advance

Hard to say without seeing the job but I might not want to risk a liquid dpm on a basement floor.
All depends on the water table but if alot of moisture pushing up under the floor a surface dpm can blow.
Does the exsisting sub floor have a sheet dpm under it?
Could you dig the floors up and put a new sub floor in?
