Pressure check water supply lines for leakage as needed.
Dig top holes (approximately 3’x3’x3’) underneath
the perimeter grade beam of the structure at predetermined pier placement
sites. (pilings will be spaced from 5 and 8 feet apart).
Place all loose dirt neatly on plywood to ease in clean up, and to
minimize disturbance of lawn and landscaping.
Any shrubs in the way will be transplanted off to the side but their
survival cannot be guaranteed.
In paved areas, such as patios and driveways, we will remove the concrete.
At completion, we will re-pour the concrete we broke out.
Use hydraulic power unit to press pre-cast cement cylinders into ground
until jacked refusal has been met (solid strata). Insert steel bit between
cylinders to link pilings together. This allows greater strength and
alignment.
Place top (trapezoid) block on top of pier cylinders that have been
driven to solid strata.
Using the top of the trapezoid block, size, and place a pre-cast cement
cylinder beside a hydraulic jack.
Using a predetermined sectional approach, raise areas of structure
in small increments until structure’s natural position has been
attained.
Using steel shims to secure the lift of the structure, place steel
shims on top of cylinder that was placed in STEP 6 above.
Remove hydraulic jacks, then size and place another pre-cast cement
cylinder beside the cylinder placed in STEP 6, using steel shims to
secure cylinders in place.
Place soil in top hole surrounding pier cap. Use a mounding approach
to allow for soil subsidence.

To make your repairs, All-American Foundation
Repair must re-support your foundation on columns. We will install the columns
by hydraulically driving them beneath the foundation. Our columns, which
are called pilings, serve two purposes. First, the pilings serve as platforms
upon which we set jacks to raise the settled portions of the foundation.
Second, the pilings transfer the weight of the building from the unstable
surface soils to deeper, more stable layers. The process individually tests
the bearing capability of the soil and piling at each location.
The pilings will be spaced from five to eight feet apart around the section
of your house that has settled. At each piling location, we will hand-dig
a hole that is approximately two feet square. The dirt from the holes will
be put on plywood to protect your grass. Any shrubs in the way will be transplanted
off to the side but their survival cannot be guaranteed. In paved areas,
such as patios and driveways, we will remove the concrete. At completion,
we will repour the concrete we broke out. The patches are poured carefully
to match the texture of the original concrete as closely as possible, but
they may not match the color of the older concrete. A hairline crack will
show where the old material meets the new.
