I took out a chimney recently, and knocked out hearth to level the floor and filled the gap with a strong mortar. Since then I'm getting moisture rising up where the old hearth was.
I can bash out the mortar, but what would you suggest to DPC the old hearth? How should it be sealed/dpced against the current concrete floor?
Cheers,
