    Issue with gaps under coping after re-grouting job?

    Good afternoon,

    I hired a pool company to re-grout the bluestone coping on my pool. While doing that, they actually ended up pulling up most of the bluestone pieces and re-adhering them to the pool structure. Some were a touch wobbly.
    So, ultimately, the coping was regrouted and re-cemented, I guess you'd call it. Very sturdy, which is good.

    However, when they cemented the coping pieces back in place, they left a gap between the coping pieces and the pool wall- as if the cement covered the inner, say, 80% of the coping piece - with a small gap remaining around the outer edge.
    When looking at the pool wall, you see the water level, then the tile, then grout/cement, a 3mm gap where water can get in somewhat, then the bluestone coping pieces. So, it's not completely sealed up any more.

    I attached four pics to illustrate - first pic just shows the pool itself. Second pics shows a view of a piece of coping that was replaced. Third/fourth pics are increasingly zoomed in versions that show the gap. Note that the last pic is really zoomed in - that black gap is maybe 3-4mm high really. And, you do hit cement further into the gap - they just didn't get cement all the way out to the pool side, leaving that gap above the pool tile.

    Now, the company has basically walked away from the work, refunded the money, saying they can't come back and fix it. Another battle. That aside, is this something that left unaddressed will be highly detrimental to the pool? Is this something critical to get fixed before swimming picks up?

    I live in Atlanta so I'm not subjected to freezing water to any large extent. Thanks for the guidance - hate to think about paying someone to come back and redo it! But, don't want to harm the pool - some water can certainly splash up in there, but seems limited?

    Take care, Michael

    That shouldn't be a significant issue. Some water will splash in there occasionally, but is unlikely to ever cause any real damage.
