Abstract: A pile cap of homogeneous material is disclosed that includes a top member part having a relatively large top area and a base member part having a correspondingly smaller bottom area. The sides of at least the bottom member part are thereby tapered. The bottom area preferably includes a recess for accommodating the top of a cylindrical pile. The shape distributes even an unbalanced load having an off-center moment of force to the top of the pile without creating potentially damaging shear stresses along the sides of the pile cap.

Abstract: A self-piloting compressible piling is provided comprising a plurality of pre-formed pile sections having bores therethrough and adapted to be arranged in end-to-end relation such that the bores are concentrically collinear. An auger plate is positioned beneath the lowest of the sections and has an upper face and lower face. The lower face of the plate has a plurality of curved blades extending therefrom. The plate further has a flared bore concentrically collinear with the bores of the piling sections through its center such that the diameter of the hole is greater on the upper face than on the lower face. A tension-bearing cable having a collapsible lock-jaw mechanism secured to one end thereof is provided which is extendable from above the highest of the piling sections through the bores of the sections and the bore of the plate and engageable with the lower face of the plate for loading the sections and the plate in compression.

Abstract: A foundation support apparatus having at least one concrete piling having a plurality of vertical piling sections surrounded by a sleeve having a plurality of vertical sleeve sections is provided. The vertical piling sections extend from the foundation to below the subsurface water table. The sleeve sections form a continuous sleeve capable of protecting the piling from uplifting soil pressure occurring in the zone of moisture change.

Abstract: A hanging jack clamp for hanging a jack upside down in a vertical orientation comprised of a bottom component, a top component, and threaded-rod-and-coacting-cylinder combination connected therebetween. The bottom component includes a base with an outer upright and an inner upright which encompass a portion of the grade beam or similar part of the foundation. Additional securement by threaded clamps can be used to more securely position the clamp if desired. A pad for distributing load forces is spread on the upper surface of the base of the bottom component where it contacts the grade beam. The top component has a member with horizontal holes through which rods are inserted. These holes are aligned with predrilled holes in the mortar between the first row of bricks and the foundation so that the rods are inserted through the holes in the horizontal member and into the holes in the mortar.
