Provided are a concrete foundation structure capable of firmly fixing a precast concrete foundation to a ground, and a method for constructing the concrete foundation structure. A concrete foundation structure 10 includes a precast concrete foundation 16 having a projecting portion 30 embedded in a ground G. An anchor plate 20 is placed inside an excavation hole 18 formed in the ground G, and the precast concrete foundation 16 and the anchor plate 20 are connected by a connecting member 22. In the excavation hole 18, a backfill portion 24 is formed of a backfill material 94 including a solidifying material and soil. A filler layer 26 is formed of a filler 96 containing a solidifying material between the precast concrete foundation 16 and the backfill portion 24. The precast concrete foundation 16 has a through-hole 42 through which the connecting member 22 is inserted, and the filler 96 forming the filler layer 26 is filled through the through-hole 42.

A system for retaining a flowable and curable building material to form a portion of a foundation includes side walls disposed in a predetermined configuration having a first side wall and a second side wall, and at least one component having an interior cavity disposed in one of the side walls. A bracket assembly includes an outwardly bounding reinforcement post for each of the side walls, a separator bar having a plurality of apertures sized to receive and retain each of the reinforcement posts at locations corresponding to nominal widths of the at least one component. A barrier is disposed between the outwardly bounding posts. The barrier and the component in the side wall is retained in the foundation after the building material cures. The barrier prevents backfill from filling a volume between the outwardly bounding posts.

A cement form includes a single piece, unitary body member having a solid, continuous construction and a wedge-shaped cross-section. The body member includes a first surface arranged vertically and configured to support a volume of cement, a second surface arranged horizontally and configured to contact a ground support surface, a foam material, an elongate construction with a greater length dimension in a horizontal direction than a height dimension in a vertical direction, and a notch formed at an intersection of the first and second surfaces, the notch being receptive of a portion of a foam sheet or other foam extension member.

Embodiments of the present disclosure relate to a system for reinforcing compressible soil strata. The system comprises at least one helical rigid-inclusion comprising a elongate body, a top member secured to one end of the elongate body, and at least one lower helically-formed member secured to the end of the elongate body opposite to the top member, and a load transfer platform configured to transfer at least a portion of a load from an overlying surface to the helical rigid-inclusion. Embodiments of the present disclosure also relate to methods of installing the system for reinforcing compressible soil.

A cement form includes a unitary body portion having a first surface arranged vertically and configured to support a volume of cement, a second surface arranged horizontally and configured to contact a ground support surface, a foam material, and a detachable portion. The cement form may include a connector groove formed in the weight bearing surface and extending along at least a portion of a length of the body portion. The connector groove is configured to receive a connecting member that extends between adjacent positioned cement forms. The detachable portion may be positioned adjacent to the connector groove.
