Abstract
Described herein are methods and systems for installing flooring systems that provide waterproofing or water-control capabilities. The flooring systems can utilize a gypsum material or any other self-leveling or concrete material along with a structural board or any other type of cement, wood, gypsum board, compressed board, cellulose fiberboard, sheathing board, or sheet metal material. The flooring systems include a waterproof coating applied to the structural boards to provide the water-control features. The waterproof coating covers seams between structural boards and between structural boards and the subfloor.
Claims20
A flooring system comprising:
- a plurality of wall isolation boards secured to a wall frame so that a bottom edge of each wall isolation board is adjacent to a subfloor;
- a plurality of floor isolation boards secured to a subfloor in a targeted area, the targeted area lying within a first portion of the subfloor adjacent to the plurality of wall isolation boards;
- a waterproof layer that covers each of (i) a perimeter edge of a second portion of the subfloor, (ii) the plurality of floor isolation boards, and (iii) an exposed, outward portion of the plurality of wall isolation boards;
- cementitious product poured in the second portion of the subfloor so that the poured cementitious product is level with a top side of the plurality of floor isolation boards such that the plurality of floor isolation boards define a pour stop for the poured cementitious product;
- and
- a sealant applied on top of the poured cementitious product such that the sealant covers intersection locations between the poured cementitious product and the isolation boards.
