Bitumen floor

[Dibley]

Hi I've got a problem with a bitumen floor or ash felt floor. It's on a bungalow built in the 1940's ex council. The bitumen or ash felt is rippled and in one place lifted quite a lot. I have had some conflicting advice on this, one person said the whole floor has to come up but others say it's repairable. Either way I'm getting a company to do it as I don't want the responsibility of maybe compromising the damp proof, I just need some help and advice so I know what I'm up against. Any ideas or advice.
Thanks
Dibley.

Why has the asphalt flooring lifted? Any signs of damp - its typical then(1940's) and now to lay asphalt as a damp proof membrane (DPM)?

To lift your asphalt might have needed quite a bit of damp pressure - in which case, the sub base and asphalt must come up. Typically it would be re-laid on DPM below a poured concrete slab.

Only a site investigation can determine the actual conditions. eg. is the external ground level higher than the interior floor levels, is there any damp in the walls?

Are you referring to a single room eg. a kitchen, or the whole house footprint?

Google mastic asphalt flooring . You should then find a local specialist floor layer

Thanks for that
There's no sign of or smell of damp, the rippling is in about half the footprint but the lifting is just in one room.

I've had a look on Google for floor specialists but I think I better get a surveyor to have a look
