A support for installing facing materials such as ceramic tiles on a substrate such as floors, walls and ceilings wherein the support plate has a plurality of spaced apart recesses in the plate material, with the recesses being open at the top surface and have solid sidewalls and a base, and a plurality of slots in the non-recessed portions of the plate material extending through the top surface and bottom surface, the slots joining one or more adjacent recesses. The support plate of the invention is used for tile installations between the substrate and such tile. Thin-set mortar that is used to secure the tile to the support plate flows into the recesses and into the slots forming a continuous bond between the mortar and the adjacent slots providing for a strong bond between the support plate, mortar and the tiles.

A laminated foam composite backer board comprising: a foam core; a first adhesive layer on each face of the foam core; a polymeric film layer on the outer face of each first adhesive layer; a second adhesive layer on the outer face of each polymeric film layer; and a non-woven fabric layer on the outer face of each second adhesive layer.

The invention relates to a decoupling mat (1) with a continuous plastic layer (2), for example one fabricated via deep drawing, comprising elongated, rib-like formations (3) on a first broadside (B.sub.1), wherein the formations (3) simultaneously form groove-like recesses (5) on a second broadside (B.sub.2) lying opposite the first broadside (B.sub.1). In order to achieve a solution advantageous for use, emphasis is placed on having the formations (3) be bordered in their longitudinal extension (1) by sections (9) of a reduced height (h′) and/or width (c′), which simultaneously also form partial areas (10) of less depth (s′) and/or width (d′) bordered relative to the recesses (5). In addition, the invention relates to a floor structure, in particular in a building with a decoupling mat (1).

The invention relates to a paver supporting apparatus and generally includes a support structure having support surface, a modular grid, and a plurality of pavers positioned on the modular grid. The modular grid is positioned on and secured to the support surface and includes a body, an extension extending from one side of the body, and a plurality of fastener receiving passageways positioned through the body and the extension.

Separating membrane of plastic material, made up of a bossed and waterproof sheet which is coupled with a permeable base layer. The bosses are of the cylindrical type with a double diameter and have such a shape and arrangement as to feature improved adhesion on both faces. The gripping of the adhesive is increased in order to obtain greater tear strength, on the upper face, and at the same time increases the area of contact with the base layer for a greater resistance to delamination on the lower face. In particular, inside each chamber there is an internal crown, which divides it like a necking into two superimposed compartments having the same diameter, wherein the first compartment has a depth amounting to at least ⅓ of the total. A production process for obtaining the membrane is also disclosed.

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.

Described herein are methods for installing field-assembled flooring systems wherein the underlayment is a hybrid design that includes a combination of structural board and cementitious product. The hybrid design is 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 structural 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.

An uncoupling mat includes a flexible plastic layer (2) made of plastic film with structuring that defines indentations (6) provided with undercuts (5) on a first, top side (4) and cavities (8) positioned between the indentations (6) on an opposite second, bottom side (7). A fleece or fabric (3) is securely connected to the bottom side (7) and covers the cavities (8). A cross-section of the indentations (6) in at least some corner regions (10) increases from the bottom side (7) toward the top side (4).

A composite structure for a floating floor system including at least one layer of force muting material and a layer of formwork, wherein the layer of formwork is located on the at least one layer of force muting material wherein the layer of formwork is a half closed folded honeycomb structure or a relaxed honeycomb structure.
