Abstract: At least one esterified fatty acid, particularly a fatty acid from tall oil that undergoes a Diels-Alder reaction or a fatty acid from oleic sunflower oil that undergoes an epoxydation reaction, is used as a PVC plasticizer, particularly for floor coverings.

Abstract: A floor covering having a double rollable reinforcement, of the type comprising on the front a calendered sheet of predefined thickness, a first reinforcement, a layer of foam and a second reinforcement, made from polyester material comprising a grid and a non-woven layer on the back, is characterized in that the first reinforcement comprises a single glass grid.

Abstract: A floor composed of a plurality of modular elements comprises a first subassembly consisting of a base component and a first intermediate element and a second subassembly consisting of a second intermediate element and a top component forming a point elastic floor. The two subassemblies are secured together by connecting means with an angular orientation offset such as to define the contact surfaces and allow assembly by interlocking. The intermediate elements are disposed with a median honeycomb structure sandwiched between two stiffening plates of the same format and dimension. The plates are of nonwoven material and have reinforcement and stiffening disposed in a canvass of warp and weft threads.

Abstract: The invention relates to a method for laying a floor covering that includes a flexible material containing a thermoplastic wear layer made from, in particular, plasticized PVC. The basic panels that form the covering are glued to the ground and cold welded in between on the site to be covered. After a panel has been positioned and glued to the surface to be covered, a continuous bead of mastic, which is made on the actual site by mixing a hardener and a polyurethane resin in aqueous phase, is applied laterally along the entire depth of the covering. The next panel is positioned on the ground which is covered with adhesive and the lateral edge thereof is pinned against the edge of the preceding panel comprising the bead of mastic, thereby causing the excess material to come to the surface, where it is removed by simply wiping with water.

Abstract: This floor is remarkable in that the plurality of modular elements comprises a first subassembly consisting in the association of a base component (A) and a first intermediate element (B) and a second subassembly consisting in a second intermediate element (C) and a top component (D) forming the point elastic floor, the two subassemblies (S1-S2) being secured together by connecting means with an angular orientation offset such as to define the contact surfaces (13) and allow assembly by interlocking, and in that the intermediate elements (B-C) are disposed with a median honeycomb structure (6) sandwiched between two stiffening plates (7-8) of the same format and dimension, said plates being of nonwoven material and having means of reinforcement and stiffening and in that the plates have means of reinforcement disposed in a canvass of warp and weft threads.
