Abstract:
1. A waterproof base providing connection between a tile drain and a drainpipe, the waterproof base comprising: an expanded polymer core defining a top surface and a bottom surface, the top surface sloping toward a drain opening extending through the polymer core from the top surface to the bottom surface, and further comprising a drain receiving recess in the top surface and extending at least partially through the expanded polymer core surrounding the drain opening; a waterproof top layer applied over the top surface of the expanded polymer core; a bottom skin applied to the bottom surface of the expanded polymer core at least around the drain opening; a rigid upright flange, the rigid upright flange projecting upwardly from the bottom skin and extending above the top surface of the expanded polymer core about at least a portion of the periphery of the expanded polymer core, the rigid upright flange directly abutting and surrounding at least a portion of the periphery of the expanded polymer core, and the rigid upright flange having a thickness of no more than 0.25 inches; and an adjustable drain top having an upper drain flange for mounting over the drain receiving recess in the top surface of the expanded polymer core, and a drain conduit extending through the drain opening through the expanded polymer core for engagement with a drain clamp mounted to the drainpipe.
