Assembly and method for joining drain pipe to concrete catch basin

Abstract

An assembly and method for joining a drain pipe with a concrete catch basin, structural elements of the assembly including a concrete catch basin having a wall, the wall having inner and outer surfaces, the wall further having a plate embedded within the wall between the wall's inner and outer surfaces, the wall further having an outer aperture extending through the concrete wall from an outer surface of the plate to the outer surface of the concrete wall, and further having an inner aperture extending through the concrete wall from an inner surface of the plate to the inner surface of the concrete wall; the method including steps of cutting a pipe receiving aperture through the plate, lining the pipe receiving aperture with an expansible elastomeric ring, extending a drain pipe through the ring, and injecting elastomeric foam into the ring, causing the ring to expand, and to seal between the aperture and the pipe, securely holding and sealing the drain pipe in place upon the catch basin.
