Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel. The floor panels may have a first and a second connector at the long edges that are configured to obtain a minimum of friction facilitating a displacement, by a spring back force from the bending of a short edge locking strip, of a new panel in a horizontal direction along the long edge during the vertical snap folding action.

The invention relates to a composite tile for an installation system, more particularly for the production of a floor covering or wall covering, comprising a tile of a floor covering or wall covering and a backing disposed on the lay-on face of the tile. The invention also relates to a connecting element for the connection of two composite tiles and to an installation system composed of composite tiles and also to a method for the fabrication of a composite tile. The backing consists of a fiber composite material, more particularly fiber cement.

A mat unit is formed from at least two layers ultrasonically welded together. Each layer is individually formed from non-vinyl nontoxic thermoplastic elastomer (TPE) material. In ultrasonically joining the two layers together, there is no need to use additional materials, such as adhesive (i.e., chemical attachment) or stitched thread (i.e., mechanical attachment) to form the joint/weld point. Once formed from the two layers, the mat unit has four quadrants and a plurality of longitudinal ribs integrally formed in the first layer positioned in the first and third quadrants, and a plurality of transverse ribs integrally formed in the first layer positioned in the second and fourth quadrants. Additionally, there are a plurality of longitudinal ribs integrally formed in the second layer positioned in the second and fourth quadrants, and a plurality of transverse ribs integrally formed in the second layer positioned in the first and third quadrants.

A construction and methods of assembly and construction of boards, e.g. floor boards, are described. The boards have a peripheral connection arrangement for interconnecting of one board to another, a core layer e.g. made from a wood or fiber based material and a top layer applied to the core layer which may be decorative and may include or provide a wear layer. A further bottom layer may be applied to the underside of the core layer and is designed to be in contact with the floor or an underlay can be applied when in use. The connection arrangement includes interconnecting hooking tongues and corresponding catches which co-operate to produce both vertical and horizontal locking.

Floor panels are shown, which are provided with a mechanical locking system comprising tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.

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 landscaping block having a block body with at least a first side surface, a second side surface, a third side surface and a fourth side surface, and opposed and substantially parallel top and bottom surfaces. The patio block having at least one spacer projection extending outwardly from each of the at least first, second, third and fourth side surfaces. The patio block having at least one spacer locator positioned along each one of the first, second, third and fourth side surfaces. The at least one spacer locator positioned along each side surface has a retaining surface shaped to receive a spacer projection, at least a portion of the retaining surface extending outwardly from the side surface.
