Thread: Bump in Liner from Concrete Underneath

  1. Back To Top    #1

    Bump in Liner from Concrete Underneath

    We had our pool installed in May. We have noticed 2-3 bumps in the liner caused by aggregate sticking out of the concrete below the liner. None have torn through the liner, but they are fairly pointed or sharp pieces of stone. Is this normal? Do PB inspect every square inch of the concrete for smoothness prior to installing the liner? Should I be concerned? Thanks.

    I would say it is a cause for concern if you feel it could pentrate the liner.

    The PB should be notified. Is it on the floor or the walls....those two surfaces are different materials.

    I had a similar problem. Under my contract if it was reported in the first year of installation no charge. After one year $300 to drain, pull liner and remove pebble, then install liner.

    They are all on the floor, where the concrete would be. I haven't noticed any on the steel walls.
