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.

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.

A method for the reduction of liquefaction potential within soil of a stratum located a distance deep below a foundation of a structure through the injection of a two-part polyurethane liquid forming a polymer foam.

A post-tensioned tube foundation for supporting a structure subject to high upset forces is described herein. The post-tensioned tube foundation includes an outer CMP positioned within an excavated hole. A foundation plug is positioned within the cavity of the outer CMP and extends across the bottom of the excavated hole. An inner CMP is positioned within the cavity of the outer CMP such that an annular space is defined between the inner CMP and the outer CMP. A tubular concrete base is positioned within the gap defined between the inner CMP and the outer CMP. A void forming element is positioned within the gap defined between the inner CMP and adjacent the top surface of the foundation plug.

The present disclosure relates to a pole shield for extending around a pole structure. The pole shield comprises a sheet of composite material forming a hollow structure having an open first end and an opposed open second end. The sheet of composite material comprises from about 0% to about 80% by weight of a reinforcement impregnated with about 20% to about 50% of a polyurethane resin composition comprising a combination of a polyol component and a polyisocyanate component. Two or more pole shields may be stacked one on top of the other to form a pole shield structure which extends the height of protection of the pole structure. The pole shield can be used for protecting a pole structure from damage, such as from fire, rain, wind, sand, ice, pests, moisture or electrical. The pole shield may also be used to provide structural support to a pole structure.

The present invention is directed to an apparatus for mixing two or more materials underground. The apparatus comprises at least one hose in fluid communication with containers of the materials that are to be mixed. The apparatus further comprises a mixer in which the at least one hose is terminated. The mixer has at least one aperture for receiving the at least one hose. The mixer further defines a mixing chamber in fluid communication with the at least one aperture to receive the materials entering into each aperture through each hose for facilitating mixing thereof in the mixing chamber. The mixer further includes an outlet for discharging the mixture.

An edge stabilization assembly for inclined surfaces having a synthetic tuft assembly; a water-permeable polymer mesh connected on one side of the synthetic tuft assembly, and a tuft-free non-permeable woven polymer mat connected on the other side of the synthetic tuft assembly, and a plurality of fasteners.

Methods, and apparatuses used in those methods, of countersinking injection tubing below the surface of a structure, such as pavement, so that injection tubing will not extend above the surface of the structure even after movement of the soil, for example, due to frost heave or shrink-swell. Some embodiments employ an injection tube extension and/or an injection tube advancer to countersink the injection tubing within the soil beneath a structure.
