Hi - I'm a bit worried that the brick mortar is crumbling away in my house below the damp proof course. House is fifty years old and I was wondering if this is normal. How do most house builders stop the damp and moisture below damp proof course eating away at their brick mortar?
I know it can't have helped matters that the previous owner layed patio slabs nearly level to the damp proof course. I have now taken away the patio slabs and dug down about four or five inches. The trouble is that the mortar on these lower rows has turned to the consistency of wet, crumbly sand. I was actually able to poke in a screwdriver all the way through into the cavity. Is my house going to fall down? I'm not sure what to do about this.
