Extensible shells and related methods for constructing a support pier are disclosed. An extensible shell can define an interior for holding granular construction material and define a first opening at a first end for receiving the granular construction material into the interior and a second opening at a second end. The extensible shell can be flexible such that the shell expands when granular construction material is compacted in the interior of the shell. A method may include positioning the extensible shell in the ground and filling at least a portion of the interior of the shell with the granular construction material. The granular construction material may be compacted in the interior of the extensible shell to form a support pier.

The present disclosure includes systems, devices, and methods for correcting foundation heave. Some systems may include a compressed air source configured to propel air having a relative humidity that is less than or equal to 30 percent and one or more air injection devices each configured to be disposed within an earth formation to deliver the air. Some air injection devices include an elongated body having: a length that is greater than or equal to 3 feet, a sidewall that defines a conduit extending along a longitudinal axis of the elongated body, the conduit being configured to be in fluid communication with the compressed air source, and a plurality of perforations, each extending through the sidewall and in fluid communication with the conduit.

A blindside waterproofed building foundation system and method of forming the same are provided. The system includes a lagging wall, a monolithic waterproof layer adjacent to the lagging wall, and a foundation layer adjacent to the monolithic waterproof layer. The system and method provide a monolithic waterproofing layer that can remain adhered to a foundation surface even if the materials used to construct the lagging wall deteriorates, decomposes, or moves over time.

The invention relates to a manhole element (a shaft element) (1) for forming at least a portion of a manhole structure (a shaft structure) (2), which manhole element is comprised of a base body (3) delimiting a hollow space; wherein at least one detection device (4), which is designed to detect and determine at least one detection variable, as well as an associated transmission device (5), which is designed to transmit the detection variables acquired by the detection device (4) to at least one communication partner, are integrated into the base body (3).

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 components may be formed into a palletized kit.

System and means soil stabilization and moisture control for building foundations including methods and systems for stabilization moisture in a site for building foundation by applying soil moisture stabilization material in various forms, a preferred stabilization material being a mixture of aluninosilicate Pozzolan mineral and granular material such as sand.

Seal arrangement for a joint of two joint elements, in particular realized as a monopile and a transition piece, of an offshore structure, preferably an offshore wind energy installation, in particular a substructure thereof, in which, for the purpose of producing a stable joint, an upper joint element and a lower joint element are inserted into each other in a clamping manner by means of at least one seal unit, comprising one of the joint elements and the at least one seal unit fixed to the joint element, in such a manner that the seal unit, in a joining position, is arranged between an inner joint surface of one joint element and an outer joint surface of the other joint element, at least one seal unit having at least one elastic sealing element, which extends in the circumferential direction around the entire circumference and the thickness (D) of which is greater than the thickness (D) of an adjoining seal unit region and method for producing a seal arrangement.

This invention discloses a method for treating sand or sandy soil in desert or desertified land, comprising spreading water and a solid organic substance in any order or by directly spreading an adhesive and cohesive solution containing the solid organic substance onto the surface of desert or desertified land, and then stirring the solution containing the solid organic substance or mixing water and the solid organic substance with sand on the surface of desert or desertified land in a uniform way by a stirring device to finally form a modified sand material. This sand treatment method can be directly implemented on the surface of desert or desertified land without transporting and discharging the mixture onto the surface of desert or desertified land, and thus saving cost and time.

Elements, methods, and systems are presented for facilitating construction of a tiered wall of elements most or all of which are oriented along the wall. Such elements may each have a front, for example, that extends between opposite sides of the wall. Such walls may include localized widening or graduated element weights, for example, engineered to allow advantageous pressure distributions over those of conventional retaining walls. Alternatively or additionally such elements may include frontal projections that stabilize a curvilinear wall by allowing an element to penetrate an adjacent element of the same tier in one or two dimensions.
