A drain coupler includes a drain coupler body having a lower opening and an upper opening. A pliable seal is carried by or adjacent the upper opening, the pliable seal operable to form a water-tight seal about an exterior of a metallic throat section of a drain. Coupler engagement structure is carried by the drain coupler adjacent the upper opening of the drain coupler body. Cap engagement structure is carried by a cap. The cap engagement structure and the coupler engagement structure cooperatively enable removable engagement of the cap over the upper opening of the drain coupler body to temporarily cover the upper opening of the drain coupler. The cap is removable to allow insertion of the metallic throat section in the pliable seal.

Building panels including a first and a second panel and including a locking device. The locking device includes a tongue and an edge groove provided in the second panel and the first panel, respectively, wherein the tongue and the edge groove are configured to cooperate with each other for locking a first edge portion of the first panel to a second edge portion of the second panel in a first direction. The locking device further includes a separate tongue provided in an insertion groove and a tongue groove configured to cooperate with each other for locking the first edge portion to the second edge portion in a second direction. A length of the tongue groove along an edge portion may be smaller than a length of the edge portion. A length of the insertion groove along an edge portion may be smaller than the length of the edge portion.

A non-wicking underlayment board and methods for forming the same. The non-wicking underlayment board includes a foam core formed of closed cell foam with reinforcement layers encapsulated within the foam core. Outer facings formed of mineral coated nonwoven fibers are positioned on opposite faces of the non-wicking underlayment panel. The non-wicking underlayment board is useful for efficient and cost effective installation of barriers and surfaces in water-resistant and waterproof environments.

Aspects of the present invention concern the production of draining porcelain stoneware tiles. Aspects of the present invention more particularly concern a tile with rectangular quadrilateral shape and edges with thickness (S), with a planar outer surface on which a series of variable geometry grooves are provided according to a drainage direction on the outer surface, wherein a drain fulcrum is defined at a central point on the substantially planar surface of the file and drainage direction are defined as extending radially inward from edges of the tile toward the drain fulcrum, and each of the plurality of grooves extends from the first end to the second end thereof in one of the drainage directions. The geometry of said groove can be triangular, trapezoidal or elliptical section. The vertexes of these embodiments form the bottom of said groove with height h, and said height h increases according to said drainage direction generating an inclined drainage plane of said groove.

A floor tile comprising a base substrate and a laminate layer, wherein the base substrate comprises a top layer with a laminate layer receiver on a top surface thereof and a bottom layer with connecting means for engaging with connecting means of a base substrate of a further tile to form an interconnected flooring system. The top layer of the base substrate extends over connecting means on at least one side of the base substrate, characterized in that the base substrate further comprises waterproofing means for engaging with waterproofing means of a base substrate of at least one further tile to provide a waterproof seal between the tile and at least one further tile.

A bathroom floor waterproofing system includes: a flat floor panel made of stainless steel; at least one drainage unit provided at the floor panel; side walls formed by bending a pair of opposite edges of the floor panel upwards; and a fastening unit comprising a male fastening plate formed by bending one of the edges of the floor panel upwards so as to be perpendicular to the floor panel and a female fastening plate into which the male fastening plate of an adjacent bathroom floor waterproofing system is detachably fitted and coupled.

A panel having a substrate and a top layer provided thereon, wherein the top layer comprises at least a melamine resin and a binder, the binder being selected from the group comprising: polyacrylates based binder, polyvinyl acetate based binder, polyester based binder, acrylic copolymers based binder or urethane based binder.

The invention relates to a panel suitable for constructing a waterproof floor or wall covering, wherein the panel has a substantially planar top surface, a substantially planar bottom surface, and at least four substantially linear side edges. The invention also relates to a process for producing a panel according to the invention. The invention further relates to a panel obtainable by said process according to the invention.

A molded shower pan includes a base having a drain opening. A plurality of strengthening ribs extend downwardly from the base wherein the spacing between adjacent ribs is a function of rib height.

An expansion joint profile system for producing an expansion joint in the manufacture of a rigid floor covering includes a profile (1) comprising a first profile element (3) having a first support leg (5) provided for bearing on a substrate (18) and a first abutment leg (6) projecting upwardly therefrom. A second profile element (4) has a second abutment leg (6). A connection element (9) is formed in a ridge-like manner and extends in the longitudinal direction between the two profile elements (3, 4) and connects them to one another in the lower region. An insertion opening (10) is formed between the abutment legs and is open at the top and extends in the longitudinal direction (L). A sealing element (11) is formed in a T-shaped cross-section with a downwardly projecting insertion leg (12) for insertion into the insertion opening (10).
