So I can install that on the inside of the walls?
It's the back wall and the right side wall that are leaking so can I join the pipes at 90 degrees?
Any idea what size the pipe is as I'll need to get some sort if timber floor above?
Can I make my own using half round down pipe?
They are single skin block walls but they are built just inside stone walls, one of which is a sort of garden party wall and the other is basically a retaining mountain wall!
Because he built these walls a few inches in from the existing walls he formed a cavity which is now bridged by all...
Just after some advice please.
We did some work for a customer on an old mid terrace property, the makeshift rear extension was leaking from the roof so we built a new front wall and put a new pitched roof over, sorted no more water coming in from the roof but the floor is still soaking wet...
