uneven asphalt floor

[gail259]

Hi ,can anyone help me, i have sold my late fathers house and the buyers surveyor reported possible sulpher attack on the ground floor as it is uneven asphalt covering, I have had a bore test done and it is negative no sign of any sulpher , but i am woundering what to do next, one floor specialist told me the asphalt should not be removed as it is a DPM and it should be screeded, is this the best option as i need to finalise the sale and i dont want the surveyor picking faults with the repair to the floor.
Any advice please.

Its not down to you to begin remedial works for any aspect of your house sale. Sell as is.

If this sale doesn't go through then the next sale disclosure statement might require you to reveal that you've been investigating sulfate attack due to a faulty surveyor's report - dont make disclosure worse by digging the floor up.

That is, that you have not tried to conceal any faults. If the asphalt is historical then say so to any buyer or surveyor.

Find out, if possible, what reasons the surveyor had for identifying uneven asphalt with sulfate? Do you have a copy of the report?

Thanks for your reply,i have seen the report and he states that a bore test was requires to determine why the floor is uneven as possible sulphate attack.As i said this is negative and well below goverment guide lines but he is still insisting that there is something wrong with the concrete and it need to be replaced hence he will not alow the couple who are buying the house the purchase price and is saying it will cost 10k to replace.
I have the engineer who done the bore test coming back out to take a closer look at the ashpalt sub floor. Nightmare

Can you post some pictures?

Is the Ashpalt cracked? You can screed over it which will get it flat

The building company i have spoke to said screeding it would be the best answer as the ashphalt is a DPM and a liquid DPM would not be suficient to stop the damp rising through the concrete, BUT the surveyor is saying otherwise.

That's correct the Ashpalt is a dpm. I have put a liquid dpm over some too over the years. Not direct but screed, dpm , screed ontop of Ashpalt.
