Abstract

A waterproof deck includes a deck subflooring supported on joists adjacent a building, a flashing adjacent a building, and a drip edge attached along the edge of a subflooring where the water runs off the deck. An elastomeric waterproofing material covers the subflooring and a strip of T-bar edging is attached along the edge of the subfloor and has a portion extending over the elastomeric waterproofing material and over the drip edge and another portion extending above the subfloor to form a raised edge therealong. Concrete covers the elastomeric waterproofing material and subfloor to the top edge of the T-bar raised edge so that water on the concrete flooring runs off the deck over the T-bar drip edge and drains from beneath the concrete floor over the drip edge to prevent collection of water over the concrete flooring.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a waterproof deck and to a method of making a waterproof deck and especially to an apparatus and method which prevents the accumulation of water between a concrete floor and the waterproof membrane on the subfloor.

[0002] In the past, it has been common to make concrete decks for apartment buildings and the like in which the deck is placed between walls on three sides and open on the fourth side. Decks are typically made with joists mounted between the walls and a plywood subfloor attached to the joists. Typically, a waterproof membrane, such as building paper, coated felt roofing material, roofing asphalt or the like, is used to coat a subfloor and then a concrete flooring is poured on top of the waterproof coating to form the floor. A drip edge is commonly used along the open edge of the deck. The deck may have a slight slope so that rain or water falling onto the deck drains off the concrete and over the drip edge. P...
