A vertical joint system for substrates is formed with joints and which engaged by relative motion in a direction perpendicular to major surfaces and of the substrate. The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints and are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints and can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

A method of folding plastic composition flooring, including but not limited to LVP, LVT, SPC or WPC, to form a desired shape, such as stair noses, baseboards, quarter rounds, T-moldings, endcaps, or the like. The method includes the steps of incorporating a thermal insulation layer between the plastic composite flooring and a heat generator, applying heat until reaching a heat transmission coefficient to allow the plastic composite flooring to become malleable, removing the heat, applying pressure to the heated section of the plastic composite flooring to form into a desired shape using a positive and negative embossing die mold on the top and bottom heated section of the plastic composite flooring, and removing the embossing die-molds once the plastic composite flooring has cooled down to its initial temperature.

Systems and methods can include scoring a backing material of a luxury vinyl plank (“LVP”) to allow an otherwise rigid plank to flex within a scoring section. The scoring section can include multiple parallel grooves that reach a depth that partially scores the backing material. The LVP can be positioned on a stair tread such that the scoring section wraps around an edge of the tread nose. The LVP can be clamped on top and bottom of the stair tread nose to allow adhesives to take effect. A scoring device can include a blade assembly with multiple blades to create multiple scored grooves in one pass.

The invention relates to a glue-down decorative floor covering system. The invention also relates to a glue-down floor covering realized by a plurality of tiles of the glue-down floor covering system according to the invention. The invention further relates to a tile for use in a glue-down floor covering system according to the invention.

A tile aligning and leveling system that uses an under tile base re-usable upright connecting tab, which is detachably connected to said under tile base, a re-usable flexible edge slotted cap configured to slip over the connecting tab and latch thereto as the cap is slid further down the connecting tab. The cap has an edge slot so that the connecting tab can be separated from the cap, by merely sliding the cap, so that the connecting tab passes through the slot. A flexible spring-like portion of the cap provides increased force on the tile even if undesired elongation of the connecting tab occurs.

The invention relates to a tile panel which includes a support panel which is essentially flat and has a top side onto which one or more tiles are adhered by an adhesive, wherein the support panel is made from a material which is different than the material from which the one or more tiles are made, and the top side of the support panel includes a recessed structure in which the adhesive is present. The invention also relates to a surface covering, in particular for a floor, ceiling or wall surface, which is constructed by a multitude of neighbouring tile panels.

An assembly apparatus for assembling a floor panel can include a platform to support a base layer and a top layer of the floor panel. The platform can include a first wall configured to contact a first edge of the base layer and a first edge of the top layer. The platform can further include second wall adjacent to the first wall and configured to contact a second edge of the base layer and a second edge of the top layer. A sensor unit can determine whether the first edge of the base layer is aligned with the first edge of the top layer, and whether the second edge of the base layer is aligned with the second edge of the top layer.

A multilayer floor covering comprises a resilient top covering (12) for providing a walking surface, a sheet-type sensor layer (16) arranged underneath the resilient top covering, a first adhesive layer (14) attaching the resilient top covering to the sheet-type sensor layer and a second adhesive layer (18) for attaching the sheet-type sensor layer to an underlying subfloor (20). To facilitate access to the sheet-type sensor layer, the first adhesive layer (14) is configured to provide lower resistance to peeling than the second adhesive layer (18). The invention further proposes a kit of parts for achieving such a floor covering as well as a method for installing the floor covering.

Provided is a building material that is disposed between an inter-floor separation layer configured to separate floors of a building having a plurality of floors from each other and a bottom layer disposed above the inter-floor separation layer. The building material includes a support member disposed between the inter-floor separation layer and the bottom layer, having a top surface of which at least a portion contacts the bottom layer, and including a protruding portion protruding downward, extending in at least one direction, and having an inner space and a plurality of damping members disposed between the inter-floor separation layer and the support member and each of which has a lower plate contacting a portion of the inter-floor separation layer and an upper plate contacting a portion of the support member to allow the inter-floor separation layer to be spaced apart from the support member.

A walkway pad is provided for placement on a flat roof to protect the roof from foot traffic, tools, and/or equipment. The walkway pad includes a body and at least one expansion joint that absorbs thermal movement of the body. A method of manufacturing the walkway pad is also provided.
