Waterproof engineered floor and wall planks have a veneer layer bonded with a plastic composite core, and an underlayer, preferably an underlayer of cork.

A panel configured to be used for constructing a floor covering that includes a plurality of such panels. A combination of locking elements is used on the flanks of the coupling profiles on the sides of the panel that provides for replacing the well-known tongue and groove coupling.

Building panels, such as a floor panels or wall panels, which include a first mechanical locking system at respective parallel and opposite third and fourth edges, such as long edges, configured to cooperate for horizontal and vertical locking between two adjacent building panels, preferably by a folding motion. The panels further include a second locking system at respective parallel and opposite first and second edges, such as short edges, configured to cooperate for horizontal and vertical locking of two adjacent building panels. An upper edge portion of one of the third edge or fourth edge, preferably the third edge, includes a first lower lip portion configured to cooperate with a first upper lip portion of an upper edge portion of the other of the third and fourth edge of an adjacent panel when the third and fourth edges are arranged in locking engagement.

A rectangular panel has long and short edges, such that on each long edge and on each short edge, the panel has a coupling part, which allows the panel to be coupled to another similar panel.

A method of creating a magnetically adhered, static dissipative floor covering (1). The method comprises the steps of providing a magnetically receptive floor surface (3), and supplying a floor covering comprising a plurality of static dissipative, magnetic floor tiles (4). The tiles (4) are held in place by magnetic interaction between the tiles (4) and the magnetically receptive surface (3). The floor tiles (4) are of composite construction comprising a) a static dissipative vinyl wearing layer (5), b) an integral, conductive ground plane (6) and c) an integral, planar magnetic layer (7), The conductive ground plane (6) comprises a non-woven synthetic fabric (8) with a nickel-copper coating and a conductive adhesive backing (9). The conductive ground plane (6) is bonded to the static dissipative wearing layer (5) by the conductive adhesive backing (9).

A paperboard or fiberboard sheet is provided with at least one preapplied adhesive strip used to connect together and an adjacently positioned surface protector to form a dust-proof and/or liquid-proof seal between the two surface protectors.

Floor covering, made of floor elements, which, at least at two opposite sides, comprise a male and a female coupling part, which allow that two of such floor elements can be interconnected at the respective sides at the respective sides by pushing one of these floor elements with the associated male coupling part, by means of a downward movement, home into the female coupling part of the other floor element, wherein at least one of said coupling parts, either the male coupling part or the female coupling part, is made as least partially in a filled synthetic material composite, such as extruded wood.

A method for reclaiming rubber comprises the steps of: (i) providing a starting material comprising a vulcanized rubber polymer; (ii) subjecting the starting material to mechanical stress and at a temperature of at least 200° C. to achieve at least a partial destruction of the cross-links and the backbone structure of the rubber polymer into fragments; and (iii) reconstituting at least part of the fragments in the presence of a branching/grafting agent to obtain a renewed rubber composition.

A preparation method of a loose lay plastic floor includes the following steps: (a) subjecting a wear layer, a printing layer, a semi-rigid PVC layer, a core layer and an adsorption layer to hot-melt compounding and shaping to obtain a composite board; (b) coating one or more layers of UV coating on a surface of the wear layer of the composite board; and (c) subjecting the composite board coated with the UV coating to tempering, conditioning and punching to obtain a loose lay plastic floor. The core layer is a stone plastic core (SPC), a wood plastic core (WPC), a high density fiberboard (HDF), or a medium density fiberboard (MDF).

A walk-behind floor scraper machine for removing floor covering from a floor surface is disclosed. In one aspect, the machine includes a base frame, an electric motor secured to the base frame, and a scraper assembly movably secured to the base frame and driven by the electric motor. The machine also includes a rear wheel arrangement including a pair of wheels having a rotational axis. In one aspect, the machine includes a hydraulic circuit with a hydraulic pump driven by the electric motor and a hydraulic motor powered by the hydraulic pump. The hydraulic motor has a drive axle coupled to the wheels, wherein the drive axle is coaxially aligned with the rotational axis. In one aspect, the machine can include a hydraulic tank-frame integral to the chassis of the machine that simultaneously stores hydraulic fluid and structurally supports the hydraulic motor.
