Thread: Coping Grout Question

    Coping Grout Question

    We had our pool installed last year. We've had grout issues since it was installed and are looking to have it re-done.

    We have an expansion joint behind our grout stones filled with caulk (not sure what is underneath the caulk), coping stones with cracking and shrunken grout between each stone, and then grout beneath the coping stones where they butt up to the actual pool itself. The grout there is falling out in chunks.

    We have several estimates, but none of the masons want to do the whole thing, they want to caulk over the grout in the underneath joint and they want us to drain our pool to do the work.

    I have one bid that I feel better about. He has estimated the full job, which includes removal of all grout, regrouting between the stones, and using caulk in the underneath joint around the pool.

    There is a strange thing in his bid though. He wants to do 9-11 expansion joints between the stones by caulking between those stones instead of grouting those. The rest would be grouted. Is this normal?

    I forget the exact dimension, but in tile layouts you need an expansion joint every 20 feet or something. He clearly thanks expansion is causing the grout failure. Got pictures?

    We're going to move forward with repairs, was just wondering if anyone could confirm the contractor's approach described above.

    Re: Coping Grout Question

    Coping looks like concrete chunks, so here is some reading on its expansion

    http://www.johnbridge.com/articles/conc ... ol-joints/

    Here is info I was talking about earlier http://www.johnbridge.com/vbulletin/sho ... php?t=1976

    My gut says either poor original job or you have expansion issues. Your repair guy seems to understand that possibility. It may be that you could go with fewer joints than he is wanting to do, but you are paying him for his expertise.

    They do make sanded caulk that can match grout with color and texture (somewhat).
