    Pool bottom heaving

    Recommendations on a good tutorial for adding a well point, or permanent sump to keep the Ground water at bay.

    pumped out all water, took out liner now fighting the ground water in Minnnesota.

    It caused the pool bottom to heave up now I will need to repair a large section of the pool bottom.

    Will the Vermiculite sold a home depot work?
