A perforated geocell is made from a plurality of strips that form cells. Each cell wall has a single pattern of perforations spaced evenly over the cell wall. This avoids uneven distributions of stress over the cell wall, reducing deformation of the geocell.

A system and method to create or elevate a berm of a liquid retention facility by placement of lightweight liquid impervious. The system and method can also be used to elevate the liquid retention height of the berm in combination with impervious liner retention material. By constructing the berm system on an existing levee, the effective height of the levee can be increased. The lightweight fill material provides the shape of the berm or levee extension. The liquid impervious liner material provides a watertight surface, the media for joining of the lightweight fill material, and the anchoring of the lightweight fill material to the existing berm or levee structure. The system may use solid wall hollow body structures to elevate the berm. The system may also use lightweight frames to support the vertical elevation of a liner above the berm.

A reinforced wall system comprising fill material, a plurality of facing baskets, a plurality of reinforcing members at least partially disposed within the fill material, and an impermeable membrane at least partially encapsulating at least a portion of the fill material and one or more of the reinforcing members. Each of the plurality of reinforcing members is associated with a corresponding facing basket. An outer end of each reinforcing member is above a substantially horizontal portion of the corresponding facing basket. The facing baskets and the reinforcing members are positioned in a plurality of layers, with each layer comprising one facing basket and one corresponding reinforcing member. The impermeable membrane is positioned to span two or more layers of the plurality of layers. At one or more layers of the plurality of layers, a portion of the impermeable membrane is positioned around an outer end of the corresponding reinforcing member.

A method of stabilizing a dike using a ground anchor assembly, includes: connecting a ground anchor to a first end of a tensile member; introducing the ground anchor through the earth body and into a stable layer beneath the dike; providing a pressure distributing member on or around the tensile member at a position within the dike where stabilization against lateral earth movement is required; and connecting a second end of the tensile member to a counter member at an outer surface of the dike.

A berm comprises fill material having a sloped face portion, a plurality of reinforcing members disposed within the fill material, and an impermeable membrane encapsulating the fill material. The impermeable membrane is impermeable to fluid and comprises a plurality of joined impermeable membrane segments. The sloped face portion is encapsulated by at least a portion of each of two or more of the impermeable membrane segments. Where two impermeable membrane segments encapsulating the sloped face portion meet, an upper end portion of a lower one of the impermeable membrane segments extends into the fill material and a lower end portion of an upper one of the impermeable membrane segments overlaps the lower one of the impermeable membrane segments in a shingled fashion.

A system and method to create or elevate a berm of a liquid retention facility by placement of lightweight fill material anchored by impervious liner material(s). The liner materials can be part of the liquid retention pond. The system and method can also be used to elevate the height of the berm in combination with impervious liner retention material. By constructing the berm system on an existing berm, earth embankment or levee, the effective height of the system structure can be increased. The liquid impervious liner material provides a watertight surface, joining media, and the anchoring of the lightweight fill material to the existing berm. The system may use solid wall hollow body structures. The system may also use flexible and liquid porous geotextile structures including geotubes. The liquid impervious liners retain the liquid in the retention pond.
