Occasionally water comes into our cellar. We already have a sump pump and perforated collecting pipe down there which works fine, but in recent years it has started coming in at the opposite corner.
The specialist who did the sump pump 14 years ago proposes to deal with it by running another perf pipe across the floor into the existing sump.
The floor is 3" thick stone slabs on a cement bed over a plastic dpm. The dpm will have to be cut diagonally across the floor - about 8ft - for the new pipe.
The specialist says he can rejoin it and put the slabs back on top, but there is a risk it may let water in. If that happens the whole floor will have to come up for a new dpm.
What do you think? Is it possible to rejoin a dpm successfully?
