Hi,
We recently pulled up the vinyl floor in our fairly recently bought house and found this very damp mouldy concrete below. We may have noticed this sooner had the radiator pipes (buried on the concrete) not been covered up with pipe covers hiding the blue stuff creeping up the pipes from the ground (not leaking down from the radiator). The floor definitely feels a lot more damp around the middle and towards radiator than further out.
Our assumption and that of our plumber is that this is a leaking central heating pipe buried in the concrete and we have been quoted to re-pipe all the downstairs rads from upstairs (our choice rather than dig up and fix leak). We regularly have to bleed air from the upstairs towel rail so a leak somewhere is a safe bet.
I just wanted to get opinions though on a couple of things... I can see the pipes are covered with a thin black plastic and furry stuff so should have been protected from the concrete? Is a central heating pipe leak the most likely explanation? This part of the house is around 200 years old, however the whole house was doubled in size in 1985 and presumably concrete pad and central heating dates to then.
Once the pipes in the concrete are drained and not in service will the concrete dry out itself (we are using a dehumidifier) and is there anything that will need to be done to it, or the whole thing digging up and relaying?
I really appreciate any input, this house is becoming a nightmare!
Thanks,
Stefan.
