The disclosure relates to a covering system for a floor, a wall and/or a ceiling. The covering system includes a decorated side, a lower side opposite the decorated side and a plurality of interconnected covering elements. At least one conducting element is arranged between at least two of the covering elements in such a way that the at least one conducting element is at least partially visible on the decorated side. The at least one conducting element is configured to conduct a physical quantity, material or signals. The at least one conducting element includes an interface to a source or a consumer of the physical quantity, material or signals.

A grout removal tool has a first long grout scraping board with an elongate through slot and a second long grout scraping board having at least two drill holes aligned with the slot for accepting screw bolts, the boards held together by screw bolts and wingnuts the boards adjustable to extend the overall working length of the tool. The tool further including a depth adjustment block mounted to one of the grout scraping boards, the block installed over threaded posts seated into the end of the host scraping board and extending through an elongate slot or slots with wingnuts, the depth adjustment block adjustable to preserve an offset dimension leveraged by an operator to remove excess grout from around a fixed feature by placing the offset block down on top of the fixed feature and removing grout around the feature according to the offset dimension.

A building panel, such as a floor panel or wall panel, has a first mechanical locking device at a respective first edge 11 and an opposite second edge, such as long edges, for horizontal and vertical locking of similar or essentially identical building panels in an assembled position. The building panel further has a second mechanical locking device at a respective third edge and an opposite fourth edge for horizontal and vertical locking of similar building panels or essentially identical building panels in an assembled position. The first mechanical locking device includes, at the first edge, a tongue groove 111 configured to receive a first locking tongue at the second edge.

A flooring element suitable for connection to other elements in a flooring system. The flooring element comprises a body, a female connector and a retainer. The body defines a connector surface that is horizontal when in use. The female connector comprises a connector recess which is suitable for receiving a male connector and also which defines a connector opening in the connector surface. The retainer is connectable to the body such that, while it is connected to the body, the retainer is movable between and open position and a closed position. When in the closed position, the retainer is arranged to restrict movement of the male connector to guard against the male connector exiting the connector recess through the connector opening. When in the open position, the retainer does not restrict movement of the male connector thereby permitting the male connector to exit the connector recess through the connector opening.

A flooring buckle has a buckle body with opposite sides and opposite ends that are transverse to the sides. The buckle body has four locking members extending outward from the buckle body. The flooring buckle has a I-shaped cross-section when viewed from the ends of the buckle body. The flooring buckle is symmetric about its vertical and horizontal center. The buckle body has a hole on an end that is configured to receive an expansion body. A diameter of the hole is sized smaller than a diameter of the expansion body. The flooring buckle is configured such that at least one of the four locking members is deformed and a portion of the deformed locking member engages a slot of a flooring panel when the locking member is inserted in the slot of the flooring panel and the expansion body is inserted in the hole of the buckle body.

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.

Floor panels and floor elements therefore are made of sheet-shaped cores which are formed with sealing means for preventing or counteracting changes in the properties of the floor panels caused by moisture. A floor panel, including a body having a core, in which floor panel at least two opposite parallel joint edge portions are provided with connectors for mechanical joining of the floor panel in the horizontal direction with similar floor panels, the connectors having active locking surfaces for cooperation with corresponding active locking surfaces of adjacent floor panels after the floor panel has been joined therewith, the core having an upper surface layer, wherein a material seal of a resilient surface layer covers the upper surface layer of the core.

The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

A joint filling profile for forming a joint sealing between floor slabs includes a vertical leg projecting into the joint and a profile body formed from a joint sealing compound and located in a joint widening. The vertical leg and the profile body are separated from each other with the interposition of a first separating material, wherein at least one second separating material is arranged between the vertical leg and the profile body and/or at least one reinforcing mat is arranged within the profile body. The second separating material and/or the reinforcing mat are arranged in such a way that they overlap with the first separating material at least in regions.
