I'm building a new workshop on the end of my garage. Because of the ground slope the workshop floor - concrete with membrane - is some 450 mm below the garage floor. There's some 300mm high of exposed and potentially damp brickwork below the 150mm garage concrete floor which also has a membrane.
What is recommended for sealing this brickwork. I suppose if I had been thinking I should have run the membrane for the new concrete floor up to the garage floor level, but I wasn't thinking that far ahead !!
Thanks Rob
