Clay tile basement question?
I have an old house that the basement is made from clay tile blocks. These blocks are hollow. I had an excavator do some digging today on one end of my house so the corner is exposed. Should these be filled with mortar mix. I don't know if they leave them open for water to flow through. I am afraid if I plug them that water will get in but not be able to get out, other than through all the joints. Anyone ever work with this stuff? I think you have to be an oldie to have ever used these. TIA
