Scheduled a foundation repair? Below are the steps we take to install segmented pilings:
Access to the interior is necessary because we need to utilize three to four electrical outlets that are on separate circuits – used to power units that will be driving the pilings.
Concrete pilings are then pressed down with the ram using power units. The weight of the structure will be used to drive the pilings. As one piling is driven, another piling is placed on top of the driven piling.
This process is repeated until the required depth and resistance is reached. The depth of the pilings will be determined by the soil makeup at your residence. This depth can range from 12 feet to over 24 feet.
Remember, frictional resistance is the key factor in driving pilings; therefore depth is not as important as friction/resistance. After the pilings have been driven to the proper friction/resistance point, a piling cap is placed between the driven piling and the grade beam.
After all pilings have been driven and piling caps have been installed, we will begin raising the foundation in stages.
We will raise the lowest portion first and then work around the area to be repaired, and in most cases, we will then work back to the lowest area and raise it more.
Once the lifting supervisor has reached a satisfactory elevation, the tops of the piles will be shimmed under the grade beam. Then the holes will be back filled, concrete patches will be made, and plants will be replanted. A final walkthrough with the homeowner is desired at this time.
