View of one of the foundation wall cracks caused by settlement in the soils. This crack was behind the oil tank in the basement, which needed to be temporarily moved while repairs were completed.
The crew had to break through the concrete slab in the basement in order to get to the main foundation footing.
Before jack hammering out for the Push Pier brackets, a concrete drill bit is used to make several holes and weaken the concrete in the footing. This allows the jack hammer to take off uniform pieces, leaving stright edges for easier installation for the piers.
The brackets are put in place. The piers will slide through the bracket, be pushed into the soils, and once stable will be tied into the footing for complete stabilization.
While the piers are pushed to the necessary depths individually, when lifting the structural they are connected through hydraulics and lifted together.
Once the piers are installed and stabilization is completed, the piers are backfilled and well compacted. As this project was done from the interior, new concrete was poured over the holes to repair the slab.
Due to settlement at the foundation walls, the main support beam at the center of the home was also sagging at one end. Once the push piers were used to lift and stabilize the wall, a SmartJack column was then installed beneath the beam to stabilize it and provide additional support.
One side of this home in Woburn, MA was suffering from settlement issues due to poor soil conditions. The repair entailed 7 Push Piers, 1 Smart Jack, PolyLEVEL for sunked concrete, and a couple crack seals.
