A modular foundation support system includes modular foundation support components including shafts provided with integrally formed coupler features on their respective distal ends. The coupler features are configured with a non-uniform wall thickness defining a plurality of sections of respectively different diameter to matingly couple the shafts to one another in a torque transmitting relationship. The coupler features may be integrally formed and fabricated on the distal end of each respective shaft.

A modular foundation assembly for building a modular foundation for a home includes a tarp that has a plurality of openings each strategically positioned on the tarp to facilitate the ground to be marked for a foundation. A plurality of concrete forms is provided which each has a trapezoidal shape. In this way each of the concrete forms can be lifted upwardly from a concrete member formed by the concrete forms when the concrete member has cured. Each of the concrete forms has a crenellated edge to form a series of slots into the concrete member. In this way the series of slots in the concrete member facilitate the concrete member to be lifted with a forklift.

An underpinning pile assembly for supporting a structure upon the earth has a plurality of pile segments, a cable extending through a continuous passageway of the plurality of pile segments, and an anchor assembly positioned at the top of the plurality of pile segments. Each of the plurality of pile segments is stacked one upon another. The cable has a lower end affixed to one of the plurality of pile segments. The anchor has an opening that receives a portion of the cable therein so as to fix a position of an upper end of the cable. The anchor assembly has at least one column extending upwardly from an upper surface thereof. An adjustable support is affixed to the column and has a surface opposite the column that is adapted to support the structure thereon.
