groundwork / damp proof membrane
Can anyone please recommend a builder who would be suitable for a job which probably consists of replacing the concrete sub base, and repairing damp proof membrane below, in my exisitng extension.
My over-enthusiastic efforts to install wet under floor heating have led to possible piercing of membrane !
esentially job is concrete mixing with a bit of damp proof knowledge.
thanks in advance
Pete

thanks Deirdre.
However, after taking further advice, I have decided that the problem is not so severe as to require help from outside, or removal and replacement of concrete sub floor.
Instead, I will rectify the problem myself, by sealing the membrane with waterproofing product squirted into the holes I drilled too deep !!
Also possibly I will paint a coat of Synthaproof onto the top of the concrete.
thanks anyway
Pete
