I've spent the last few months working on damp proofing our cellar (house is ~1850s) and I'm wondering what's going to be the best way to finish the floor. Plan is for a bit of a home cinema / playroom.
I'm pretty satisfied with the walls now - I've used 8mm dimpled membrane all the way around and cut a perimeter drainage channel in the floor slab, installed a decent sump etc. I've drilled holes around the sump chamber itself, which seems to be doing a pretty good job of draining the surrounding ground too.
Previously, there'd usually be about an inch of water down there for 6 months of the year.
State so far
The damp on the floor in the pictures is mainly from the new concrete that had just gone down to close the channels - it's almost dried out now.
The ventilation is reasonable and I'm planning to have a dehumidifier down there to help too.
The walls and ceiling will be plasterboarded and skimmed.
I'm now at a stage where I need to decide what to do with the floor. Id like to ulimately carpet it. Head hight is an absolute premium down there and I can't really lose more than a few mm. The concrete floor is about 70mm thick and has no DPC, with clay soil beneath.
Its difficult to tell how bad the slab will be for moisture - its dusty dry at the moment but I'm not too confident about laying carpet directly on top of it.
Plan A was to put 8mm dimpled membrane on the floor, float board over and carpet. Unfortunately theres just not sufficient head height for this.
Ive got a few rough patches to self-level (latex?)
I'm wondering about either using slimline 1mm membrane (https://www.permagard.co.uk/p-seal-1-floor-40m.html) or maybe epoxy coating such as https://www.permagard.co.uk/liquid-epoxy-damp-proof-membrane-5-litres.html - or even just paint?
What would be the suggested way to handle this?
Also, how would carpet be 'fixed'? Presumably gripper strips aren't easily fixed and glue probably isn't ideal either?
Thanks!
