The invention relates to a method for laying a modular surface covering system on a surface to the covered and an underlayment element for use in such a method and modular surface covering system. The underlayment element includes a planar base with a raised edge along two interconnected sides of the underlayment element. First coupling elements in the form of recesses are provided along the two sides with the raised edge and second coupling elements in the form of protruding tongues are provided along the other two interconnected sides. The finishing layer elements are clamped between raised edges of coupled underlayment elements. The top surface of a raised edge between finishing layer element provides the grout effect. The underlayment elements enables one to lay a surface covering system with a multitude of pattern, e.g. as grid pattern, brickwork pattern, herringbone pattern, etc.

A construction panel for installation on a construction surface and interlocking connection to a another construction panel comprises a moisture barrier base to inhibit migration of moisture from the construction surface. The base has a pair of opposed first connector edges comprising a first pair of releasable mating elements, and a pair of opposed second connector edges comprising a second pair of releasable mating elements. A plurality of projections extend from the underside of the base for support and to permit air circulation and drainage of water between the base and the construction surface. In one embodiment, an upper panel having selected physical characteristics is attached to the base. The positioning of the first and second pairs of mating elements on the first and second pairs of connector edges enables the interconnection of entire or partial construction panels.

A system for underlayment of a flooring has at least two foam panels having and a complementary under step portion on one side an an overstep portion on an opposite side. The understep portion has an adhesive strip with a release liner. The panels are joined by placing the overstep portion of one panel over the understep portion of an adjacent panel and removing the release liner. The overstep portion is then adhered to the overstep portion to seal the panels together. A method of grinding foam strips to form the panels is disclosed.

A load distributing and absorbing system that lies below a superstructure material which is exposed to percussive forces. The load distributing and absorbing system is interposed between the superstructure material and a foundation. The system has a barrier layer that lies below the superstructure material and an underlayment infrastructure positioned below the barrier layer. Included in the underlayment infrastructure are hat-shaped absorbing members.

The invention relates to a surface element (1), intended for use as a floor, wall and/or ceiling surface element for a floor, wall and/or ceiling covering, having at least one carrier plate (2) and at least one functional layer (3), wherein the carrier plate (2) comprises a top side (5) facing a usable side (4) and an underside (7) opposite the top side (5) and facing the underground (6). According to the invention, it is provided that the functional layer (3) is provided underneath the carrier plate (2), and that the functional layer (3) is designed in such a way that, in the installed state, it projects beyond the side edge (10) of the side (8), in particular of the long side (9), on at least one side (8), especially on at least one long side (9).

A bathroom floor waterproofing system includes: a flat floor panel made of stainless steel; at least one drainage unit provided at the floor panel; side walls formed by bending a pair of opposite edges of the floor panel upwards; and a fastening unit comprising a male fastening plate formed by bending one of the edges of the floor panel upwards so as to be perpendicular to the floor panel and a female fastening plate into which the male fastening plate of an adjacent bathroom floor waterproofing system is detachably fitted and coupled.

A method and apparatus for minimizing tissue adhesion in a tissue of a subject includes applying light, to the tissue, that reduces at least one adhesion marker in the tissue, the light having wavelengths in at least one of a first wavelength range of 730-770 nm and a second wavelength range of 930-970 nm, wherein the at least one adhesion marker includes at least one of a transforming growth factor beta 1 (TGF-β1), a vascular endothelial growth factor, (VEGF), and a collagen alpha-1(I) chain (COL|α|), and wherein the light is free of wavelengths that increase the at least one adhesion marker.

A load distributing and absorbing system that lies below a barrier layer that is exposed to percussive and/or point-applied forces. The load distributing and absorbing system has one or more load distributing and absorbing tiles. At least some of the tiles have an underlayment infrastructure positioned below a barrier layer. The underlayment infrastructure includes one or more hat-shaped absorbing members. Each has a ceiling primarily for load distribution and a curvilinear wall primarily for load absorption extending from the ceiling. A transition feature is provided to smoothly graduate from one height and type of load distributing and absorbing tile to a load distributing and absorbing tile of another type and height. He system distributes and absorbs forces applied to the barrier layer over a broad area when applied either on a seam between adjacent tiles or within a tile.

The cushioning preform comprises two layers of foam material, e.g. polyethylene foam, laminated together in a laterally offset relation to one another, with or without a polyethylene film therebetween. Each of the foam layers is of rectangular cross-section has a surface section of greater density than the remaining section thereof. Rolls of the preform may be unrolled into a flattened condition on a substrate, such as a concrete floor, with a stepped edge of each unrolled preform overlaid by an adjacent unrolled preform and adhered thereto by a glue on the stepped edge.

The present disclosure describes a contiguous sound attenuating panel system. The sound attenuating panel has a top surface, a bottom surface, a first end, a second end, an adhesive strip on the top surface of the first end, and an engagement flap on the top surface of the second end. The adhesive strip has a first edge and a second edge. The second edge is located further from the first end than the first edge. When installed, the first end of a first sound attenuating panel abuts and is substantially coplanar with the second end of a second sound attenuating panel. The width of the engagement flap of the second sound attenuating panel terminates substantially at the location of the second edge of the adhesive strip of the first sound attenuating panel such that the engagement flap contacts and substantially covers the adhesive strip.
