● This town home foundation was experiencing severe differential settlement due to soils consolidating and suspected improperly installed original piles
● Each of the individual unit’s foundations was so badly deflected that underpinning was the better option than lifting the reinforced grade beams
● Our team of engineers studied the original plans, soil reports and existing conditions and designed a combination deep foundation underpinning with a modified micro pile push pier
● A small rotary hammer drilling rig, modified to fit in the low overhead conditions, was deployed to drill pilot holes through the buried rubble to a depth averaging 30ft
● We proceeded to push a heavy duty 4.5” Magnum Push pier to the bedrock at an average depth of 80ft and reinforced it with grout
● The uplift resistance for the high capacity push pier ram was provided by securing the unit and our custom gantry to the 16 inch reinforced concrete slab to allow for high capacity
● Each 40t bearing load pile was capped with a custom bracket to support the grade beam per the engineer’s recommendations
● Our house lifting team then leveled the homes filling the gaps created under the now leveled walls at the slab.
● The deflected floors were brought back to within standard building codes for new construction after having been deflected up to 5 inches
