Hi

I have been advised that the bitumen smell coming from one of my ground floor rooms could be due to a damp. As the blocks sit on bitumen on top of a solid concrete floor, i am wondering what my options are.

Do i get a builder in to remove the floor completely and lay a new slab with insulation etc?

Or rip up the blocks and put a liquid DPM on top of the existing slab...

I don't want to raise the floor level too much if at all.

Also don't want to spend too much cash if i can help it...!!

Does bitumen smell when it gets wet, or is it the blocks rotting and the bitumen smell coming from that..

Any help appreciated

Thanks

Are they woodblocks. Does sound like the smell is from damp under them. If you take them up then get flooring grade Ashpalt. Should be similar height.
 
Yep, woodblocks

I have a wierd damp problem around the edges of the floor, where it meets the wall. Some days it is as dry as a bone, other days damp. Take today, no rain for several days, scorching hot, but damp patch present.

No nearby pipework. No drains on outside of that wall. No leaks - when i went on holiday for a week the water meter hardly moved.

Therefore reasonable to assume i guess, that if the edges are damp the middle of the floor must be too.

I have done all the usual checks - outside ground level is below exterior DPC. Inside floor level IS slightly below the internal leaf DPC however, but it was built that way.

Who would i call to take a look at this? A damp proof co didn't want to know - its been injected in the past.

Cheers.

Think you be best putting this question on www.theflooringforum.com some good lads on there that might know. I only deal with floors myself mate, so not sure myself. If you could take a few pictures to upload that might help.
