Around 9 years ago the previous owners of our house had the basement (approx. 450 sq ft) tanked out.
All walls and floors were coated with waterproof membrane and then coated with concrete and Biokill Crown chemicals were used.
We have had damp, yellow staining, paint bubbling and water coming in at the joins of where the concrete meets between the corridor and rooms.
We called in the contractor (work guaranteed for 10 years) and he said: 'that's not damp'. I said, yes, it is and local surveyor recommended we get you back in. He then huffed about it 'never happening before' and the like.
Has agreed to strip plaster on - some of the affected areas and recoat floors.
Now, he's spoken to H (wimpy with trades) and said the floors don't need recoating and that the prob is 'no extractor fan' (windows and door ventilation) and that 20% damp in a treated basement is fine and that the floors don't need re-coating?
Is he right???
