Hi,
My brothers bathroom ( Built 1900) which was an ex coal house is having the bathroom refitted. And the walls and floor tiled.
The floor is concrete and is going to be tanked as it has no integral DPC. One of the walls in the bathrooms is a shared wall with the neighbor and has damp due to rising from the ground. He is going to inject a DPC cream in the first available mortar line. ( basically one row of bricks above the floor level)
The question is as the wall will be tiled and we need to build out the removed plaster we do not want to bridge the DPC.
Which is the correct thing to do?
1. Run the tanking up and over the DPC? Then build out with mortar with added SBR?
2. Bridge the DPC with membrane ? Then build out with mortar with added SBR?
I have created a simple drawing to explain my self better
