A water management protective mat device having a protective mat formed by a plurality of weighted tire members interconnected in a grid structure. Each tire member includes a plurality of apertures for receiving one or more rod members. The one or more rod members interconnect a tire member to another tire member. The protective mat is configured to reduce erosion along a stream bank by reinforcing erosion barriers in terrain underneath the protective mat thereby preventing water from eroded the terrain.

The present disclosure discloses an earthen dam structure including a core wall that includes a homogeneous mixture of clay, sand, powdered tire rubber and Portland cement. Additionally, the core wall contains the powdered tire rubber in an amount sufficient to increase a modulus of elasticity of the core wall to over 10 MPa while keeping a hydraulic conductivity of the core wall under 100 feet/year. The earthen dam structure further includes an upstream embankment portion and a downstream embankment portion, each positioned adjacent to the core wall, and a spillway configured to prevent water from overtopping a crest of the core wall.

A method for making substantially parallelepiped square cross-section formwork modules for building constructions, cut-off walls, embankments, dams, anti-erosion and anti-seismic foundations and/or the like, starting from used pneumatic tires, having at least the steps of: a) providing a used pneumatic tire deriving both from a periodic replacement of worn tires or from the rubber industry wastes or from the recovering of used pneumatic tires; b) removing from the pneumatic tire the two wall iron beads; c) performing cuts at diametrically opposite positions on the edges, wherein the cuts define cut-out regions separated by a middle solid region of the tire wall; d) removably mounting the pneumatic tire on basket-drum supporting means; and e) pressing in diametrical directions towards a center of the pneumatic tire the pneumatic tire tread portions near the cuts thereby causing the tire to assume a substantially parallelepiped configuration.

Seabed scour about a seabed-mounted foundation or renewable energy device or anchor therefore, especially a wind-turbine monopile may be prevented or reduced by installing on or in the seabed area about the foundation or device an arrangement of interconnected sedimentation elements, which by virtue of the elemental structure or interconnective arrangement themselves do not cause or worsen seabed scour by substantially displacing seabed material on which the elements are placed. Elements having a specific gravity, either in situ or inherent, of substantially similar to the seabed material or mobilized seabed material in which they are placed are capable of achieving this. An ideal arrangement of elements (or mat) is one formed of used or discarded vehicle tires.

A tire assembly for use in reclaiming land from a marine environment. An anchor having at least one cable connected thereto acts as a base to which tires are connected by threading them down the cable to form a cylindrical tower of tires which can be filled with concrete or filler if desired. A plurality of the tire assemblies can be positioned adjacent to one another and further interconnected for stability purposes and can form the basis for further structural elements.
