OK, another conservatory question:
Due to the shape of the conservatory, I need a dpm which is bigger than the sizes any of the DIY places stock. So what I want to know is - can I join two sections of dpm together, to enable me to cover the full floor area? Or is this going to let damp through?
Also, where the dpm comes up against the house wall, does it have to be physically chased into the house wall so it joins or overlaps the house dpc?
