Disclosed is a comprehensive excavation process performed on an excavation site. The process includes installing wellpoints for lowering the groundwater level within the excavation site and stabilizing the boundary soil walls of the excavation site by an improved soil nailing method. The improved soil nailing method employs casing pipes that are part of the wellpoint system as reinforcing elements for the stabilization of the soil walls.

A cementitious composite for in-situ hydration includes a structure layer having a first side and an opposing second side, a cementitious material disposed within the structure layer, a sealing layer disposed along and coupled to the first side of the structure layer, and a containment layer disposed along the opposing second side of the structure layer. The structure layer has an intersection at the sealing layer and the containment layer that is at least partially fiberless. The cementitious material includes a plurality of cementitious particles. The containment layer is configured to prevent the plurality of cementitious particles from migrating out of the structure layer.

A pocket structure for receiving containerized plants is sloped and hung from a wire of a wire basket. The pocket structure includes hooks, an irrigation fitting and corresponding drip channel to transmit water toward the rear of the pocket, and slots in the walls. The mesh units include braces and are sized for shipping. An earth wall is formed of the mesh units and pockets, and includes irrigation tubing.

The present invention is directed to a Pre-cast Decorative Retaining Wall consisting of concrete walls constructed on a horizontal surface normally at a manufacturing facility, on rolling platforms, or preferably built on the construction site where after curing to 3000 psi the pre-fabricated walls can be shipped to and installed at a building site. In the flat state the panels can have a wide variety of decorative elements readily applied to both the upper and lower downside reflection surface. A unique feature is the buttress system that is added to the back of the wall system when elevated retention is required. By pouring the buttress portion on top of the footing pier or caisson, and tying into the pre-decorated wall with reinforcement, an eco-friendly, design optional retaining wall system is accomplished which can be rapidly and safely installed.

An adjustable auger assembly for a trencher including an auger housing and a position attachment assembly. The auger housing having a central auger tube having a first end and a discharge end opposite the first end. An auger shaft is positioned within the auger tube and is rotatable relative to the central auger tube. At least one material inlet is positioned one of at the first end and between the first end and the discharge end. The position attachment assembly has a first component member coupled to the trencher, and a second component member coupled to the auger housing. The first component member is movably positionable relative to the second component member, to, in turn, adjust the position of the auger housing relative to the trencher.

A security barrier for deployment in crowd control and/or containment, the security barrier being capable of adopting at least two configurations. In a first configuration the security barrier is erected for deployment and comprises a compartment bounded at its front by a front panel for providing a barricade, at its rear by a rear panel of lower height than the front panel, at its sides by respective side panels pivotally connecting the rear and front panels, and at its bottom by a bottom panel connected at least two of the front panel, the rear panel, and the respective side panels. In its second configuration the security barrier is collapsed for storage and/or transportation.

The embodiments herein provide a method, system and a kit for building a retaining wall and repairing an existing fence. The system comprises several wedge shaped wooden posts and wooden panels for constructing the retaining wall and repairing the fence, several V-shaped metal tip secured at the tip of a wedge shaped wooden post for enhancing a penetration of the wooden post into the ground, a channel guide for aligning several wooden panels vertically with respect to the ground, and a protective cover secured with a head of the wooden post for transferring the hammering force to the wooden posts and prevent splitting of the wooden posts.
