Abstract
A penetration assembly for a polymer membrane-lined pool includes a faceplate having a weldment surface surrounding a penetration area, and a retention perimeter extending away from the weldment surface. The faceplate is formed of a polymer material allowing the polymer membrane to be heat welded directly to the weldment surface on grade with the membrane, forming a watertight seal around the penetration area. The retention perimeter is embedded below grade to keep the penetration assembly in place. A wall assembly is formed from a plurality of polymer wall panels, to bottom portions of which the periphery of the polymer membrane is continuously welded.
Claims16
A penetration assembly for a polymer membrane-lined pool, the penetration assembly comprising:
- a faceplate having a thermoplastic weldment surface integrally formed with the faceplate and compositionally compatible for heat welding to a polymer membrane liner, the weldment surface being heat welded to the polymer membrane liner to define a continuous plastic weld bead circumscribing a penetration area having a recess extending away from the weldment surface;
- an earth anchor connected to the recess and extending away therefrom;
- and
- a retention perimeter extending away from the weldment surface;
- wherein the faceplate is formed of a polymer material;
- and
- wherein the earth anchor is connected to the recess via a sealed ball joint seated in an integrally molded spherical seat of the recess, the ball joint being enclosed within the recess volume to maintain watertightness.
A polymer membrane-lined pool comprising:
- a polymer membrane lying on an underlying surface and having at least one penetration therethrough;
- and
- a penetration assembly having a polymer faceplate with a thermoplastic weldment surface integrally formed with the faceplate and compositionally compatible for heat welding to the polymer membrane liner, the weldment surface being heat welded to the polymer membrane liner to define a continuous plastic weld bead completely encircling a penetration area and a retention perimeter extending away from the weldment surface, the weldment surface being located on a grade of the polymer membrane at a location of the at least one penetration, the at least one penetration being located over the penetration area and a portion of the polymer membrane surrounding the penetration being thermoplastically welded to the weldment surface forming a complete watertight seal thereabout, the retention perimeter being embedded below the grade in the underlying surface;
- wherein the underlying surface is earth and the penetration assembly includes an earth anchor connected to the faceplate by a sealed ball joint seated in an integrally molded spherical seat of the recess, the ball joint being enclosed within the recess volume to maintain watertightness.
A penetration assembly for a polymer membrane-lined pool, the penetration assembly comprising:
- a faceplate having a thermoplastic weldment surface integrally formed with the faceplate and compositionally compatible for heat welding to a polymer membrane liner, the weldment surface being heat welded to the polymer membrane liner to define a continuous plastic weld bead circumscribing a penetration area;
- and
- a retention perimeter extending away from the weldment surface;
- wherein the faceplate is formed of a polymer material;
- and
- wherein the retention perimeter includes an outwardly sloping section at an acute angle relative to the weldment surface extending away from the weldment surface and a peripheral lip extending away from a distal periphery of the sloping section approximately parallel to the weldment surface.
