Dig top holes (approximately 3'x3'x3') underneath the perimeter grade beam of the structure at pre-determined pier placement sites.
Place all loose dirt on plywood or plastic for ease in clean up, and to minimize disturbance of lawn and landscaping.
Use hydraulic power unit to press pre-cast concrete cylinders into ground until jacked refusal has been met (solid strata).
Place cap (trapezoid) block on top of pier cylinders that have been driven to solid strata.
Remove all loose mortar from the cracks in brick veneer.
Remove all old and deteriorating caulking from exterior doors and windows.
Using the top of the trapezoid block, size and place a pre-cast concrete cylinder beside a hydraulic jack.
Using a pre-determined 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 8 above.
Remove hydraulic jacks, then size and place another pre-cast concrete cylinder beside the cylinder placed in Step 8, using steel shims to secure cylinders in place.
Low pressure mud pump under slab area to fill voids left by raising structure. This is strongly required when lifting slab more than two inches.
Place soil in top hole surrounding pier cap. Use a mounding approach to allow for soil subsidence.
Remove excess soil from site.
Pressure-check water supply lines for leakage.
Discard plywood and rake areas free of debris.
