Flexible containment tubes form sections of a dike for fluid containment. Structural supports are inserted into the flexible contain tubes and the tube sealed to form structure supported dike sections. For example, a supporting structure may be configured with a given length and cross sectional diameter to provide structural support to a vinyl-coated polyester tube with a 12-36 inch diameter. The structure is sealed within the tube and, in turn, the tube may be filled with a fluid such as water to create structure supported containment dike. The length of the supporting structure may be selected based on the width of an entryway to create structure supported dike section of a give length that provide a seal across the entryways against floodwaters.

A wall element for holding back water is formed in one piece and has a planar, rectangular main portion having a first side, a second side parallel to the first side, a third side perpendicular to the first side, and a fourth side parallel to the third side. A first planar bearing portion is connected to the main portion over the first side and perpendicular to the main portion. A second planar bearing portion is connected to the main portion over the second side and perpendicular to the main portion. The second bearing portion is opposite the first bearing portion. The wall element has a planar connecting portion connected to the main portion over the third side and inclined to the main portion. The connecting portion has connecting holes in the longitudinal direction, and the main portion has connecting holes along the longitudinal extent of the fourth side.

A flood water retention assembly for reducing flood damage includes a plurality of repositories that is each positioned proximate a lowland area prone to flooding. A plurality of drain conduits is each fluidly coupled to a respective one of the repositories. Each of the drain conduits is in fluid communication with a drainage area to drain the water into the drainage area. A plurality of inlet conduits is each fluidly coupled to a respective one of the repositories. Each of the inlet conduits is in fluid communication with a body of water to receive water from the body of water. A pump is fluidly coupled to each of the inlet conduits and the pump is positioned adjacent to the body of water. The pump pumps the water into the repositories when the pump is turned on. In this way the repositories contain flood waters thereby reducing flood damage to surrounding areas.

The invention relates to a water barrier shield foot element for supporting a protective module of a water barrier shield configured to be positioned between a body of water and an area of land to be protected. The water barrier foot element is configured to be arranged against a ground surface and extends in a longitudinal direction, wherein the foot element comprises a base element, a front end, a rear end and a first and a second longitudinal side portion. The front end is configured to be arranged in a direction towards the protective module, characterized in that the base element at one of either the rear end or the front end of the foot element is wider than the other so that the base element has a trapezoidal shape. The invention further relates to a water barrier shield support arrangement, a water barrier shield system and a method for manufacturing a water barrier shield foot element.

A compressible liquid retaining berm having a plurality of linear wall members and right angle corner members composed of a compressible, resilient material such that the wall members and corner members will rebound to a neutral state after being compressed. A longitudinal slot is disposed in the top wall of the wall members and the corner members, with the corner member longitudinal slots communicating with a recess positioned in the corner member. A liquid impermeable liner member is disposed on the interior side of the wall members and corner members, the liner member extending across the wall members and corner members. The liner member is secured to the wall members and corner members by positioning elongated anchor members atop the liner member in alignment with the longitudinal slots, such that the weight of the anchor members results in the anchor members being received within the longitudinal slots.

Flexible containment tubes form sections of a dike for fluid containment. For example, multiple vinyl-coated polyester tubes with a 19-inch diameter may be filled with water and stacked on top of each other to create a temporary diversion dike. Multiple sections of dike may be abutted together to form longer sections of dike. A vapor barrier or plastic membrane may wrap over dike sections and/or weaved through the flexible containment tubes as they are placed prior to filling. Configurations of the vapor barrier and associated anchoring mechanisms improve the utility of dike sections by reducing hydrostatic pressure of contained fluid on the dike, harnessing the weight of fluid columns, and mitigating seepage through the dike sections.

Drive-over berm systems that protect raised sections of protective containment liners from truck and heavy equipment damage are disclosed. A ramped outer berm abuts an elevated portion of the liner, which may be raised to a desired height by an insert positioned under the liner. A ramped inner berm may about the elevated portion of the liner, and a connector plate may be used to secure the outer and inner ramped berms together. The height of the raised portion of the liner is selected to provide the desired sump capacity of the containment area. The inner berm and/or outer berm may be provided in sections that can be connected end-to-end.

A modular foundation structure for artificial surface systems includes a structural base layer with a shaped rigid foam having contoured and elevated features, an adhesive layer covering the structural base layer, and an impact and thermal protective layer attached to the structural base layer via the adhesive layer. The impact and thermal protective layer is configured to support an artificial surface layer and has a relatively higher melting point and compression recovery factor than the structural base layer. The shaped rigid may be a closed-cell foam such as Expanded Polystyrene (EPS) or Expanded polyethylene (EPE), and the impact and thermal protective layer may be a bead molded Expanded Polypropylene (EPP) foam. The impact and thermal protective layer may have a melting point of about 300 degrees Fahrenheit, and the structural base layer has a melting point of less than 200 degrees Fahrenheit.

The disclosed water barrier systems may include a first mobile water barrier, and adjacent second mobile water barrier, and a translation mechanism for translating the first mobile water barrier and the second mobile water barrier toward each other. Lowering mechanisms may be configured to lower sidewalls of the mobile water barriers. The mobile water barriers may include sealing elements to form water seals between the adjacent mobile water barriers and between the sidewalls and a surface. Related methods of forming a water barrier assembly are also disclosed.
