<p>The specification discloses a plastic pool wall having a groove in its face which includes an embedded metal channel for receiving the bead of a plastic pool liner. The metal channel includes spaced upper and lower walls joined by a base wall, with the upper wall terminating short of the plastic pool wall face. As a result, the upper surface of the groove is defined in part by the metal upper wall of the metal channel and by the plastic of the pool wall. Consequently, when the plastic liner bead is placed in the metal channel and the groove grouted, grout seals between the plastic pool liner and the plastic of the pool wall.</p> |
