A foundation support system and method of installing the foundation support system. The foundation support system includes a pier system for providing support beneath a foundation, a support member, and a heave plate attachable to a bottom surface of the foundation. The method includes driving a pier system using a ram, coupling a support member to the heave plate, and engaging the support member with the pier system.

Provided are a helical pile and a bracket module comprising the same. The helical pile includes a column body, at least a helical blade and a loading member. The column body has a fixing end, a loading end opposite to the fixing end, and a body section between the fixing end and the loading end. The helical blade is disposed on the column body between the fixing end and the loading end. The loading member is connected to the loading end of the column body and includes a flange. The ratio of the body diameter of the column body to the blade diameter of the helical blade ranges from 1:3 to 1:7. The helical pile features excellent compression bearing capacity and uplift bearing capacity due to its specific element-size ratio, and is applicable for installation in areas subject to harsh conditions or with peculiar geological features or soil conditions.

A support assembly for supporting a building structure, the support assembly comprising: a pile adapted to be buried into a ground surface, the pile having a longitudinal axis; a pile head adapted to be secured to a top end of a pile, the pile head including a mounting member engaging the pile and an extendable member movably mounted to the mounting member, the extendable member being movable relative to the mounting member, along the longitudinal axis, the extendable member including: a support platform adapted to receive the support beam of the manufactured home's support frame thereon; and at least one holding member adapted to engage the building structure and to prevent movement of the support beam relative to the support platform.

A pile is comprised of a pipe, i.e., a hollow tube or hollow cylinder, with a coextensive internal reinforcement comprised of a plurality of intersecting walls. The pile is comprised of a blend of a thermoplastic and 20 to 50% (pbw) pelletized chopped strand glass fibers. The outer surface includes a co-extruded cap stock that is relatively smooth and exhibits a relatively low coefficient of friction. The internal structures exhibit roughness, bumpiness and a relatively high coefficient of friction for an extruded plastic. A groove may be formed in the pile adjacent to an end for resistance to uplift.

A foundation pier bracket system provides attachment of a pier shaft with a building or structure foundation such that the system provides securement to competent strata or soil below. The system can include a reinforcing sleeve and a bracket assembly. The bracket assembly can include a shaft receiving portion and a seat portion. The shaft receiving portion can define an aperture that is sized and shaped to receive a portion of the reinforcing sleeve therein. The seat portion can include a plurality of protruding members that protrude upwardly therefrom. The plurality of protruding members can be arranged such that they restrain lateral movement of a beam along the seat portion in at least one axis. The reinforcing sleeve can include a locking wedge that secures the reinforcing sleeve to the bracket assembly. A method of supporting a foundation of a building is also provided.

A marine navigational aid for use with a piling. This marine navigational aid comprises a flexible wrap, at least one affixment mechanism coupled to the flexible wrap, and a plurality of alphanumeric characters disposed on an exterior side of the flexible wrap.

Disclosed embodiments include a suction pile vent plug having a cylindrically-shaped body having a sealing element, a plurality of coupling features, and a handle connected to the cylindrically-shaped body. The sealing element is configured to form a watertight seal with walls of a suction pile vent into which the vent plug is installed. The plurality of coupling features are configured to engage with corresponding coupling features of the suction pile vent. The movable handle is configured to be moved into one or more locked configurations. Disclosed embodiments further include a suction pile vent having a hollow cylindrically-shaped body having coupling features. The coupling features are configured to engage with corresponding coupling features of a suction pile vent plug to thereby mechanically couple the suction pile vent plug to the suction pile vent. Disclosed embodiments further include a fluidic port that fluidically couples a suction pile to a removable fluidic coupling.

Provided are a helical pile and a bracket module comprising the same. The helical pile includes a column body, at least a helical blade and a loading member. The column body has a fixing end, a loading end opposite to the fixing end, and a body section between the fixing end and the loading end. The helical blade is disposed on the column body between the fixing end and the loading end. The loading member is connected to the loading end of the column body and includes a flange. The ratio of the body diameter of the column body to the blade diameter of the helical blade ranges from 1:3 to 1:7. The helical pile features excellent compression bearing capacity and uplift bearing capacity due to its specific element-size ratio, and is applicable for installation in areas subject to harsh conditions or with peculiar geological features or soil conditions.

The vent cap system for a suction pile includes a top plate, a center stem assembly, a bottom plate, a flange assembly, and perimeter stem assemblies. The bottom plate moves between an opened position and a closed position. The center stem assembly is in direct threaded engagement with the top plate, and the perimeter stem assemblies and stem retainer cooperate to maintain alignment of the bottom plate. A pipe plug to test the sealing engagement is placed on the bottom plate, instead of the flange assembly. There is a closing lip of the bottom plate so that a sealing diameter can be the smallest diameter of the flange assembly, which reduces force on the bottom plate from under the bottom plate. There is a connection portion of the flange assembly to attach the system to the suction pile so that weld deformation does not affect the entire flange assembly.
