Separating membrane (10) of plastic material, made up of a bossed and waterproof sheet (100) which is coupled with a permeable base layer (101); the bosses (102) are of the cylindrical type with a double diameter (D1, D2) and have such a shape and arrangement as to feature improved adhesion on both faces (110-111). The invention increases the gripping of the adhesive 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 (103) there is an internal crown (104), which divides it like a necking (D2) into two superimposed compartments (105-6) having the same diameter (D1), wherein the first compartment has a depth (H1) amounting to at least ⅓ of the total (H). The invention also relates to the production process for obtaining said membrane (10).

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.

A flooring underlayment includes a base membrane and a cover membrane. The base membrane is configured to be installed between a subfloor and floor tiles to allow movement of the floor tiles relative to the subfloor. The cover membrane is configured to be coupled to the base membrane to form a flat surface for supporting the floor tiles. The cover membrane is configured to be coupled to the base membrane using at least one of a snug fit and a snap fit.

A support for installing facing materials such as ceramic tiles on a substrate, such as, floors, walls and ceilings. The support plate has a plurality of spaced apart raised portions and recesses in the plate material, and a plurality of openings extending through the top surface and bottom surface of the plate material. The openings exposing a mat layer attached to the bottom of the support plate. Support plates of the invention are used for tile installations between a substrate and tile. Thin-set mortar that is used to secure the tile to the support plate flows into the recesses and into the openings forming a continuous bond between the mortar, openings and mat layer to provide a strong bond between the support plate, mortar and the tiles.

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.

An uncoupling mat includes a flexible layer made of a film-like plastic with structuring that defines indentations provided with undercuts on a first, top side and a series of annular cavities formed on an opposite second, bottom side. The annular cavities on the bottom side each define a recess on the first side. The indentations have a cross-section adapted to receive a heating cable therein such that the cable can be held in position by the indentations. A plurality of weakening zones each extends between two rows of annular cavities in a straight line to allow the plastic layer to move substantially transversely to the direction of extension of the weakening zones.

A flooring underlayment comprises a membrane that includes a body panel having a panel top surface and a panel underside surface spaced apart from the panel top surface by a panel thickness. The membrane further includes a plurality of dimples projecting downward from the panel underside surface, each dimple having a dimple upper end open to the panel top surface, a closed dimple lower end spaced apart from the dimple upper end by a dimple height, and a dimple sidewall extending between the dimple upper end and the dimple lower end, the dimple sidewall configured to inhibit collapse of the dimple height when a load is applied to the flooring underlayment during use. The membrane includes a plurality of grooves open to the panel top surface and formed within a groove body projecting downward from the panel underside surface, each groove shaped to receive an elongated heating element therein.

An underlay mat (10) for floor coverings, includes a polyurethane layer (14), a self-adhesive film (20) on the topside of the polyurethane layer (14) and which includes a carrier film (12), a layer of adhesive (22) applied to carrier film (12), and a mesh structure (24) made of fibers which is embedded in the adhesive layer (22), and a removable protective film (26) on the topside of self-adhesive film (20).

The invention relates to a paver supporting apparatus and generally includes a modular grid having a body and a plurality of planar adhesive receiving sections extending across a width thereof. The body includes a top surface, a bottom surface positioned opposite the top surface, a plurality of geometric lattices provided from a plurality of walls. The plurality of planar adhesive receiving sections are positioned between the geometric lattices and have a width greater than each of the plurality of walls.
