Described herein are methods for installing field-assembled flooring systems that include isolation boards on a wall frame, a subfloor, or on both the wall frame and the subfloor. The underlayment can be a hybrid design that includes a combination of isolation panels and cementitious product. The flooring systems are configured to reduce or eliminate the curing time requirement after pouring the cementitious product (e.g., gypsum concrete). The field-assembled flooring systems can reduce or eliminate the chances of the onset of mold due to high moisture levels by removing the cementitious product from the prone areas and replacing it with structural boards. The isolation boards (e.g., cellulose fiberboards) can be installed in non-critical areas such as underneath cabinets, around the perimeter of the floor, under bathtubs, in non-walk-in closets, anywhere drywall reaches the floor, or the like. The isolation boards can be installed on walls rather than or in addition to the isolation boards installed on the subfloor.

A water drainage edging segment includes a horizontally-extending bottom portion, a vertically extending top portion, and an angled intermediate section spanning between the bottom and top portions. The bottom portion defines a plurality of longitudinally spaced bottom channels that are oriented at one or both of a perpendicular angle and an oblique angle to the longitudinal axis of the edging segment. Each of the plurality of bottom channels are raised above a lowermost plane of the bottom portion to define an open passageway from a backside of the edging segment and laterally through the edging segment. The top portion defines a longitudinally extending upper rib portion that projects rearwardly from a front plane of the top portion to define a forward offset of the front plane and an upward facing contact surface.

The isolation boards (e.g., cellulose fiberboards) can be installed in non-critical areas such as underneath cabinets, around the perimeter of the floor, under bathtubs, in non-walk-in closets, anywhere sheet rock reaches the floor, or the like. The isolation boards can be installed on walls rather than or in addition to the isolation boards installed on the subfloor.

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.

The invention provides a surface covering product, in particular a floor covering product, comprising boundary walls defining a lower face which in use faces a surface to be covered, said boundary walls having an upper face extending up to 60 cm from said lower face, said boundary walls dividing a part of said surface to be covered into at least partially enclosed surface parts and providing a boundary for at least one filling composition in said at least partially enclosed surface parts, wherein said surface covering product further comprises a base web having said boundary walls coupled to said base web for holding said boundary walls in position, and said base web comprises an upper surface below said upper face of said boundary walls, and a lower surface which in use rests on said surface to be covered, said boundary walls are coupled on top of said base web, and in use said filling composition covers said base web and at least part of said boundary walls, and wherein at least said boundary walls are formed in a three-dimensional (3D) printing process.

Various embodiments of the present disclosure provide a joint edge assembly and method of positioning and installing joint edge assembly for adjacent concrete slabs. The method includes positioning the joint edge assembly in an offset position from the joint. The method of various embodiments also includes using a plurality of height adjusters or plates fixed to the slab engagement surface of the one of the joint edge members to adjust or assist in adjusting the height of the joint edge assembly relative to the formwork and relative to the plane of the top surfaces of the concrete slabs.

An edging form for use in forming a self-leveling floor includes an elongated body having a top face, a bottom face, and a first side face that extends between the top face and the bottom face, the body being made of a polymeric foam. A plurality of spaced apart channels extend entirely through the body from the top face to the bottom face and pass through at least a portion of the first side face.

The invention relates to a method for arranging an element, such as a shower board or shower drain, in a floor, which method includes the steps of: providing an element which has an upper surface with at least two straight edges lying at an angle, preferably an angle of 90 degrees. The element has a strip of a flexible watertight layer standing upright from the upper surface along the corner of the two straight edges; folding the upright strip downward, wherein the folding edge is shaped adjacently of the two straight edges of the corner and wherein the strip of the flexible watertight layer hangs downward from this folding edge; and arranging the element in the floor. The upper surface of the floor lies flush with the upper surface of the element.
