ABSTRACT:
A plastic lined concrete tank includes a floor, an upright wall having a lower edge adjacent the floor, a plastic wall lining on an interior surface of the wall, and a plastic waterstop structure inhibiting penetration of water between said floor and said lower edge of the wall. The waterstop includes an anchor embedded in the floor and an upper flange which overlaps the lining. A sealed joint is provided between the upper edge of the flange and the lining. The flange and the lining are fused together to form a supporting structure at a position lower on the wall than the sealed joint, whereby outward bending of the flange away from the wall lining at said joint during shifting of the wall relative to the floor is inhibited and outward bending of the flange away from the wall lining at a location remote from said joint during shifting of the wall relative to the floor is promoted. The tank also includes a plastic floor liner and a floor liner attachment member fused to said anchor. The attachment member is attached in sealing relationship to the floor liner.
