A waterproof panel for shower tray, adapted to be placed over a foundation, to be interposed between the latter and a floor covering layer includes at least one plate-like element and a waterproof covering which is applied on top of the at least one plate-like element, and has, on the lower face for adhesion to the foundation, and low-relief portions adapted to accommodate adhesive for the adhesion of the panel to the foundation.

Floorboards provided with a mechanical locking system including a locking strip protruding from a first edge of a first floorboard. The locking strip is provided with a locking element configured to cooperate with a locking groove at a lower side of a second edge of a second floorboard for locking the first edge and the second edge in a horizontal direction. The first edge and the second edge are configured to be assembled by a vertical downward motion of the second edge towards the first edge. The second edge is provided with a calibrating groove adjacent the locking groove. The disclosure also relates to a method for producing a mechanical locking system.

The invention relates to a multilayer lining plate for essentially horizontal support surfaces such as floors or floor coverings, comprising a main layer having at least two longer sides and two shorter sides, including at least one part, and a ductile upper decorative layer, wherein the lining plate comprises along an outer edge of each of the longer sides of the main layer a ductile machinable portion that can be machined to form a connecting profile for connection of the lining plate with other plates; wherein the at least one part of the main layer is more rigid than the upper decorative layer; and wherein the at least one part of the main layer is made of magnesium oxide, fibrocement or mortar with perlite and/or vermiculite and/or cellulose.

A planar floor covering is formed having a top face and a bottom face opposite the top face, a length, a width perpendicular to the length, a top surface, a bottom surface opposite the top surface, a height between the top surface and the bottom surface, and physical properties or characteristics that vary across at least one of the length, the width and the height. The physical properties or characteristics include material composition, weight, density, directionality, stiffness, compressibility, elasticity and thickness.

Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels. The locking system includes a displaceable tongue at least partly arranged in a displacement groove, a tongue groove, a cavity provided in a strip at the first edge, and a protrusion extending downwards at the second edge. The displaceable tongue is arranged to be displaced at least partly into the tongue groove during locking, and wherein the protrusion is arranged to be located in least a portion of the cavity when the panels are locked vertically and horizontally.

The present invention discloses a two-layer composite wood floor board, comprising a face plate and a base plate, wherein the face plate is disposed above the base plate, the face plate is glued to the base plate, the base plate is formed by peeling a log, the lower part of the base plate is provided with more than one grooves, and reinforcing ribs are disposed in part or all of the grooves. The present invention has the following advantageous effects: on one hand, the area of a single base material formed by peeling is larger so that the number of gluing is reduced for manufacturing a floor board having the same area, thereby greatly reducing adhesive consumption, and meanwhile, the increase of the outturn percentage of the log and the simplification of the machining process are achieved by manufacturing the base plate through peeling, thereby greatly improving the production efficiency.

A floor panel is provided. The floor panel composition includes a wear layer and a base layer. The base layer includes a first base sections having a first composition of polyvinyl chloride, filler, and plasticizer, a second base sections having a second composition with a higher content of polyvinyl and plasticizer than the first composition, and a glass fiber section positioned between the first base section and the second base section.

A multi-level unitary safety surface tile. The tile may be of monolithic construction. The tile may include rubber. The tile may include an upper level and a lower level. Hollow protrusions may extend between the levels. At least one protrusion may include resilient walls extending from the upper layer and converging to a protrusion bottom-cap in the lower level. Inter-protrusion ribs may span between and support adjacent protrusions. With the lower layer disposed upon an underlayer, the protrusions may support the upper level. The tile may attenuate impact forces incident upon the upper layer. The tile may constitute a unitary safety surface. The tile may include structures facilitating interlocking of adjoining tiles into a multi-tile unitary safety surface. Protrusion extensions and/or support ribs may support the structures. The tile may be manufactured in a one-piece molding process utilizing mold forms maintained parallel to opposable faces of a mold press.
