Why is my Bitument floor damp?

TigersEye

I have a bitumen floor with a carpet, my bitumen floor is wet near the wall. The wall isn't wet, but the carpet gripper is, with a bit of white powder.

You may have a damp floor, same as me. Concrete floor letting water seep into the floor tiles. Laid badly years ago and requires digging out, relining with membrane and new concrete and screed, cost £2500.

If walls are dry then I would say that it is a possibility you have the same problem but a bit of investigation may prove different.

Rustybucket how on earth can you tell the OP how much it's going to cost?!!... they haven't mentioned the size, the location (prices vary around the country).May be able to get away with just painting on synthaprufe or similar.

Is the wall external? Is there paving the other side of the wall and how far is it below the damp proof course? Any leaking gutters, nearby drainpipes, gulleys or pipes?

How on earth? Read my post properly, you'll see that I am writing about my experience, ok?

Apologies for misunderstanding you. I assumed by your use of the future case that you were implying that would be the problem and the cost - which to be fair may well be the case. How big an area was it that you had relaid so the OP has a better idea as to likely costs?

As you know, digging up a floor is messy and expensive so best avoided if possible. If painting on a bit of synthaprufe on solves the problem that's obviously preferable compared to spending a few thousand. Or there may be other options such as damp proof membrane and screeding on top of the existing concrete.

The affected area is about 30 x 90 cm, it is not right against the wall, which is an external wall.

I would like to try the synthaprufe first I think, funds are non-existent, but need lots of things.:eek::eek::eek:
