Project description
The failure of three original mono-post piers caused the structural concrete basement floor in this residence to settle. Repair required installation of three transfer beams beneath the basement floor. As replacement tiles for the marble flooring in the basement were not available, the original floor was removed. Tunnels were then cut for access to required locations so that micro-piles and transfer beams could be installed

Project description
“Slope creep” caused movement of this eight-unit mountainside townhouse building. As a result, two uphill units were sheared off their foundation walls with extensive damage to interior framing and cosmetics. Palace excavated and exposed the foundation walls, removed all of the soils, shored the units and lifted them off their foundations. New foundation walls were poured and the units were returned to new foundations. Framing damages were repaired and cosmetic damage corrected, returning the units to a like-new condition.

Project description
Severe foundation movement required the removal of the existing wood structural floor and replacement with a new concrete-over-steel floor system. More than 105 cubic yards of dirt were removed from below the floor. Some 16 inches of soils beneath the foundation walls were excavated to create a new void space. To support the foundation, two counterforts and six pier haunches were removed and replaced, and 71 linear feet of new sister wall added. The structural beams were also replaced with larger beams to support the house further.

Project description
Numerous repairs were required to correct foundation problems at this multi-family project. Soils around three sides of one building were excavated to a depth of 11 feet, resulting in the removal and replacement of over 300 cubic yards of dirt. Over 90 lineal feet of new sister wall were installed. Six new counterforts were added to support the existing foundation, requiring over 46 yards of concrete. In addition to exterior remediation, 16,700 pounds of tube-steel lateral braces were added to the interior of the units to brace the foundation at the main floor land the basement crawl-space levels.

Project description
Severe movement of this house required a complete underpinning of the entire structure. The garage slab was removed, two feet of existing soils excavated and structural fill material placed. The basement structural floor was removed due to buckling caused by lateral pressures, with soils beneath excavated and regraded. The foundation walls were revoided and a new perimeter drain was installed. A total of 31 new concrete piers were installed around the foundation of both the house and garage, after which the house was releveled. Helical tiebacks were installed to further stabilize the foundation. The entire perimeter of the house was then regraded to establish positive drainage away from the home. All exterior concrete flatwork was removed and replaced.
