A stay-in-place footing form assembly includes a plurality of inner form boards serially aligned and joined by inner joining brackets, a plurality of outer form boards serially aligned and joined by outer joining brackets, a plurality of lower spacing rails, each disposed between and connecting base brackets in the inner and outer joining brackets aligned laterally, and a plurality of upper spacing rails, each disposed between and connecting top brackets in the inner and outer joining brackets aligned laterally. The lower spacing rails include first rebar receptacle(s) for seating horizontal rebars on the rails, and the upper spacing rails include second rebar receptacle(s) for holding vertical dowel rebars therein. The inner and outer form boards are insulation boards that have an ability of absorbing lateral forces of earthquakes exerted to a concrete footing formed in the stay-in-place footing form, and an ability of insulating the concrete footing from surrounding temperatures.

Embodiments described herein relate to construction of subsurface structural elements that are configured to redirect soil forces. For instance, a form may be used to construct a subsurface structural element such that the subsurface structural element redirects soil forces to vertically displace a foundation rather than have the soil forces crack or otherwise damage the foundation.

Disclosed herein is a support base for use in shuttering formwork. The support base includes an angle section member and a plurality of clamping brackets. The clamping brackets further include clamping members engageable with the clamping brackets to define a clamping portion aligned with openings on the angle section member. Also disclosed herein is a method of supporting shuttering formwork which uses the support base.

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 at least one inwardly bounding reinforcement post and at least one outwardly bounding reinforcement post, 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 and inwardly bounding posts. 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 and inwardly bounding posts.

The invention comprises a method of forming a slab on grade. The method comprises placing a first layer of insulating material horizontally on the ground and placing plastic concrete for a slab on grade on the first layer of insulating material. The plastic concrete is then formed into a desired shape having a top and sides. A second layer of insulating material is placed on the top of the plastic concrete and the first and second layers of insulating material are left in place until the concrete is at least partially cured. The second layer of insulating material is then removed. The product made by the method is also disclosed. A slab on grade is also disclosed.

A precision fabrication form system for preparing a poured-concrete (with upwardly projecting anchor bolts) footing for anchorably supporting the base of an elongate, upright, structural-frame column. The system includes a reversibly stackable plurality of independent, intercooperative, fabrication-form templatesgrade, pedestal, base-plate, anchor-bolt and centerlinereversibly assembleable in a predetermined stack order above a prepared ground excavation into which concrete pouring to be associated with such a footing is to occur, certain ones of these templates being infinitely adjustable relative to one another and to the ground in both pre-pour and post-pour conditions to accommodate staged, precision, X-axis, Y-axis, Z-axis, and pitch, roll and yaw axes dispositions for the concrete and anchor bolts in such a footing.
