A geogrid in the form of an integral, mesh structure includes molecularly orientated polymeric material, with the integral, mesh structure being formed of interconnecting mesh defining elements including elongate tensile elements. The molecular orientation of the integral, mesh structure is uniform throughout the extent thereof.

The present invention relates to a self-supporting, prefabricated, folding form structure or mechanism to be used in the construction industry. It is based on various types of geometries, providing enhanced strength and stability for the concrete and other building material casting process. The object of this invention is a foldable, prefabricated, self-supporting form and does not require a structure. It is configured in a variety of geometric shapes and is based on structural elements that have internal casting chambers or ducts interconnected between each other through perforated holes. This is done by means of internal assembly channels or cavities forming casting chambers. The casting chambers are interconnected with each other, through holes drilled in the structural elements. This way the form features an assembly between its walls through cracks or assembly cuts, creating an architecture of superior engineering that provides higher resistance and stability.

A seismic remediation device includes a body with a first half and a second half structured to be coupled to the first half around an interface between a pile and a pile cap in a pile-supported structure. Each half of the bracket includes a base with a hollow half cylinder shape and an upwardly facing U-shaped flange coupled to the base. The bases of the halves of the bracket are securable around at least a portion of circumference of a pile and the upwardly facing U-shaped flanges of the halves of the bracket cooperate to receive a longitudinal portion of the pile cap. The halves of the bracket being coupleable to each other proximate the interface between the pile and the pile cap.

A method is for supporting a retaining wall that includes a number of wall blocks positioned to retain material against a rear side of the plurality of wall blocks. The method includes attaching the rear side of at least one of the wall blocks to at least one ground-stabilizing base body supporting the wall blocks. Kits and systems are also disclosed.

Systems and methods to provide pressed aggregate-filled cavities for improving ground stiffness and uniformity are disclosed. According to an aspect, a method includes using a mechanism to press into a ground surface in a substantially downward direction to create a concavity. The method also includes substantially or completely filling the concavity with unstabilized or chemically stabilized aggregate, soil, or sand. Further, the method includes using the mechanism to press the aggregate within the concavity to achieve a desired ground stiffness.

A method for reinforcing an aggregate pier. The method includes inserting a conical-head pipe into the aggregate pier, injecting grout into the aggregate pier by injecting the grout into the inner chamber of the hollow rod, driving the conical-head pipe into a soil under the aggregate pier by driving a secondary pipe into the aggregate pier and pushing the conical-head pipe toward the soil under the aggregate pier by utilizing the secondary pipe, filling the secondary pipe with grout, and inserting a reinforcement bar into the secondary pipe and the hollow rod. This method reinforces an aggregate pier against excess tensional and compressional loads of a concrete foundation.

A foundation lifting method includes the steps of cutting an existing concrete pile below the building foundation, inserting two sleeve portions over ends of the cut pile, placing a lifting device, such as a jack, between the ends of the cut pile and jacking vertically within the cut out section, and then fixing the two sleeve portions to reinforce the cut area. The method can be performed simultaneously or consecutively on plural existing concrete piles below the building foundation. The sleeve portion couples the lower pile portion with the upper pile portion to resist vertical and transverse loads. A computerized interface can coordinate the actuation scheme for multiple piles.

Described and disclosed is a foundation structure of an offshore structure, in particular of a wind turbine, with a floating foundation, including at least one floating body for floating on the surface of the sea, at least one anchor for anchoring the at least one floating body the seafloor and at least one holding element for holding the at least one floating body to the at least one anchor. At least one transmission cable extends from the at least one anchor along the at least one holding element to the at least one floating body and/or back. To enable a reliable monitoring of the anchoring of the offshore structure, provision is made for the transmission cable to be guided in sections through at least one protection element provided between the holding element and the at least one anchor and/or the at least one floating body.

A soil stabilizer assembly may include a pipe with a first end, a second end, and a sidewall defining a hollow shaft extending between the first and second ends; a stabilizer connectable to the second end of the pipe with a hollow body and a plurality of extensions extending radially outward from the body; and a cap connectable to the first end of the pipe including a receiving portion for receiving the first end of the pipe and a plate extending across the receiving portion. The hollow body of the stabilizer may be configured to receive the second end at least a portion of the sidewall of the pipe therethrough. The receiving portion of the cap may be configured to receive the first end and at least a portion of the hollow shaft of the pipe therein. The hollow shaft, hollow body, and receiving portion may be coaxially arranged.
