Some thoughts please for a newbie.
Due to have some building work done and want to make sure i know its done 'proper'
My house is built into a hill, so part of it is underground. As part of central heating works, a new heat main consisting of flow and return is to enter the house at its underground part (the boiler has its own external building), at 900mm beneath (exterior) ground level. It emerges about 200mm above ground level on the inside of the house. The cavity wall will clearly be breached - what is the best way of preventing damp entering? Thanks
