Hi, I bought a 6x5m DPM and had it laid for an outbuilding base - then concrete was poured around the footings over the DPM.
Turns out the DPM is too small on one side and just about comes up to where the surface of the 2nd layer of concrete will be (we are doing footings first then 200mm concrete slab over the lot after since it's easier).
I need to add to the DPM but wondering what the best way of doing it is?
Shall I just buy and slice another DPM and concatenate with duct tape, ensuring 100mm overlap?
Can't find my answer searching google.
Thanks in advance.
