A flooring product includes a first oriented strand board layer, an acoustic barrier layer, and a second oriented strand board layer, where the acoustic barrier layer is secured between the first and second oriented strand board layers to form the flooring product. The plurality of flooring products can be positioned adjacently to comprise a complete flooring assembly. Such a flooring assembly can be facilitated by including features along edges of the flooring product for securing or engaging one flooring product to adjacent flooring products. For example, the flooring product can be arranged with one edge as a tongue and an opposing edge as a groove, where the tongue of one flooring product can be fitted into the groove of an adjacent flooring product to secure or engage the two flooring products together. In another example, edges of the flooring products can be arranged to form lap joints upon engagement.

A flooring assembly comprising a flooring unit comprising a stability core layer having a plurality of edge surfaces, two of which have an interlocking mechanism for attachment to the edge surfaces of the stability core of adjacent flooring units; a plurality of sound attenuating acoustic layers attached to the bottom surface of the stability core layer; and a finish layer attached to the top surface of said stability core layer.

A device for laying floor and wall covering for outside corners includes two portions, namely a rigid central first portion that is substantially in the shape of a hollow tetrahedron or of a quarter of a truncated cone, and a flexible peripheral second portion that is substantially triangular in shape and that extends from the periphery of the central portion. The peripheral portion comes to bear against the floor portion and against the wall portions that are disposed facing the device.

A field-deployable ballistic protection system is described for protecting a structure or area from ballistic damage (such as by small arms, grenades, mortars, etc.). The field-deployable ballistic protection system includes a posterior sheet, an anterior sheet, and a spacing bracket. The posterior sheet is configured to be secured to a structure. The spacing bracket is configured to be secured to the structure through the posterior sheet. The anterior sheet is configured to be secured to the spacing bracket so as to create a void between the anterior sheet and the posterior sheet. The void is configured to receive a granular material, such as a locally-available soil, therein for providing ballistic protection to the structure. Also described are a free-standing embodiment of the field-deployable ballistic protection system and various methods of installation.

A floor element for forming a floor covering, the floor element comprising a decorative layer comprising a ceramic material, an intermediate layer comprising a resin material, and a support layer arranged below the decorative layer, wherein the support layer comprises edges provided with coupling elements configured to realize a mechanical coupling with coupling elements of an adjacent floor element and wherein the resin material comprises a modulus of elasticity greater than 0.1 GPa, preferably greater than 0.5 GPa, even more preferably greater than 1 GPa.

Interlocking panels have a top portion and side edges. Multiple panels are interlocked together mechanically along the side edges by locking features. The top portion includes a substantially planar top surface, side edges, and interlocking features. The bottom support structure is made of a shock absorption material that fits under the substantially planar top surface, thereby providing support and cushioning to the substantially planar top surface. The interlocking feature includes, for example, sides alternating between sides that have protrusions (upward or downward) and sides that have receivers for the protrusions.

A modular flooring system is disclosed to accommodate non-planar configurations of modular floor mats. Modular mats each have a main central portion and overhanging and underhanging flanges extending therefrom. The outer surfaces of the mats have treads formed thereon, which may be of different grades, such as industrial or pedestrian grade. Each flange contains a plurality of bores, each comprising a recess at opposing mat surfaces connected by a central portion. The recess depth at one mat surface differs from the recess depth at the opposing surface, creating an offset spacing to account for surface tread regardless of mat overlay and configuration. A fastener, having a head and opposite foot, is inserted through aligned bores in adjacent mats and rotated to lock or unlock mats in each configuration. The modular flooring system provides increased utility through enabling planar, stacked, and stepped configurations of the system.

A flooring assembly comprising a plurality of flooring units each unit comprising a first stability core layer having a top surface, a bottom surface and a plurality of edge surfaces, at least two of the edge surfaces having an interlocking mechanism for attachment to the edge surfaces of the first stability core of adjacent flooring units; a sound attenuating acoustic layer attached to the top surface of the first stability core layer; a second stability core layer attached to the top surface of the acoustic layer and having a top surface, a bottom surface and a plurality of edge surfaces, at least two of the edge surfaces having an interlocking mechanism for attachment to the edge surfaces of the second stability core of adjacent flooring units; and a finish layer attached to the top surface of the second stability core layer, wherein (1) each of the layers is polygonal, and the assembly of flooring units is attachable to a surface of a structure.
