Various examples are provided related to compression spacers which can be utilized in the construction of, e.g., a micropile or drilled shaft. In one example, a high-capacity compression spacer includes a grout vessel body including: a grout receiving portion defined by a bottom of the grout vessel body and a portion of a sidewall of the grout vessel body; a bar receiving portion extending from the grout receiving portion to a lip defining an opening of the grout vessel body; and a plurality of tie wire insertion holes distributed about the bar receiving portion. Each of the plurality of tie wire insertion holes can be configured for insertion of a tie wire. The grout vessel body can be a single piece, molded body. The grout receiving portion can be filled with a high-strength, non-expanding grout or concrete.

A multilayer membrane may be suitable for construction, and/ir adapted to be installed between a wall of a seat obtained in the ground and a concrete structure. The multilayer membrane may include: a first layer including thermoplastic polymeric material, impermeable or substantially impermeable to water; a second layer including thermoplastic polymeric material, impermeable or substantially impermeable to methane gas and/or radon gas and/or volatile organic compounds (VOC), fixed to the first layer and adapted to be positioned, when the membrane is installed, between the first layer and a concrete structure.

A bracing assembly for a geosynthetic wrapped system is provided. The bracing assembly includes a standing brace bar, a bottom brace bar, and a cross brace bar having different configurations to facilitate both easy and mistake free assembly of the bracing assembly. Furthermore, the standing brace bar and the bottom brace bar include guide tips that are sized and shaped to direct insertion of the standing brace bar and the bottom brace bar respectively into a weave of a geotextile fabric material such that a first connector of the bottom brace bar and a first connection slot of the standing brace bar are aligned together and with a fold line of the geotextile fabric material.

The invention relates to a below grade, blind side, waterproofing sheet membrane with adhesive and high reflectivity granular particle layer, and having a top release liner, and a bottom release liner, enhancing bond strength between sheets, and be able to fully bond to concrete/shotcrete, and a method of making, and using same. The inventive waterproofing sheet membrane with adhesive, has at least one layer of high reflectivity granular particle layer that are fully or partly embedded into the adhesive layer, and where the average reflectivity of the exposed granular particles is between about 35 percent to 80 percent reflectivity on a standard reflectivity scale. The waterproofing sheet membrane has an adhesive layer having embedded therein high reflectivity granular particles is used in any building or wall construction, and can be placed under or around a foundation of a building or on its below grade blind side retaining walls, etc.

Geosynthetic reinforced wall panels including soil reinforcing members and retaining wall system formed therewith are disclosed. The geosynthetic reinforced wall panels include any type of wall panels, such as a precast concrete wall panels, that are supported by an arrangement of soil reinforcing members. Various configurations of soil reinforcing members may include end tabs and/or inner tabs that have strips arranged therebetween. Examples of soil reinforcing members include, but are not limited to narrow-width single-section reinforcing members, narrow-width multi-section reinforcing members, and wide-width reinforcing members. Further, a retaining wall system is provided that includes any arrangement of the one or more geosynthetic reinforced wall panels.

A rotomolded lid for a meter box and a method of making the same are provided. The lid is formed in a rotomold process that embeds a pair of rebars within a hollow lid product. Concrete is then poured into the hollow portion and allowed to cure. The end result is a reinforced meter box lid that is configured to handle loads of up to 16,000 lbs. In addition, the presence of the rebars, which are ferromagnetic, allows a metal detector to detect the presence of the lid should it ever be inadvertently covered over or otherwise obscured from view. Furthermore, the central lid portion may also include a passageway covered by a hinged door to permit access to the meter box without having to lift up the lid itself. Another passageway, along with an associated countersunk portion in an upper lid surface, permits a wireless transponder to be positioned therein and connected to meter equipment in the box.

A segmental wall block, soil reinforcing system, and method related thereto, wherein the wall block may be used for constructing retaining walls. In one embodiment, the segmental wall block may include: a front face; a rear face; a slot disposed along the rear face; a troughed top face; a bottom face; a first and second open core extending from the top face to the bottom face; a first side having a tongue; and an opposing second side having a groove, wherein the tongue is shaped to interlock with the groove. A soil system may include: a wall block component including a first configuration of interlocked segmented wall blocks as described, and a stabilizing component. A method of reinforcing soil may include the steps of: installing a leveling pad of concrete or gravel; and providing a soil stabilizing system.

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.
