I am in the process of building a stud partiton wall. It is to block up french doors in what was once a solid brick wall on ground floor.
I will be drilling and screwing the lower beam of the wall frame into bricks at ground level, which already have a damp proof membrane on them. I will also be putting a DPM directly underneath my woorden beam in case the original is knackered.
Presumabely by screwing through damp proof membrane it ceases to be damp proof? How do I get around this - I wondered about putting silicaone sealant around the hole in the damp proof membrane? Or does it not really matter?
Thanks
