We had our vertical stack soil pipe replaced a number of months ago (old asbestos type to plastic). At the base of the pipe in the garage a concrete upstand has been formed about 150mm high, I presume to protect the old SVP when it was in place. I have noticed a damp patch around the base of the concrete, which gets worse when you flush the toilet or run alot of water down the soil pipe.
I think when the pipe was replaced it looks like a connector was only pushed into the concrete upstand and not directly into the clayware underground cpnnector, which is I presume just above the garage floor. I presume the water is coming down the pipe and forcing its way into the concrete and therefore into the garage.
Has anyone got any suggestions how I can get the concrete off without damaging the clayway pipe below?
Also what type of connector do I use to convert the plastic soil pipe into clay?
