HOW ARE THEY INSTALLED?

The installation process is simple.
- In each location where a piling is going to be installed, a hole is dug next to the foundation. Each hole is about the size of a doormat. The holes go down 2 feet below the bottom of your foundation.
- Next, a concrete cylinder is placed in the bottom of a hole and under the foundation.
- A high power hydraulic ram is then placed on top of the cylinder. The ram sits on the cylinder and the top of the ram touches
the bottom of the foundation. - The ram is activated and used to push the cylinder down into the soil. The pressure applied to the cylinder will often exceed 50,000 pound!
- Once a cylinder is driven all the way into the ground, another cylinder is set on top of the first cylinder.
- The two steel bars are then cemented into place.
- The second cylinder is the pushed into the ground, driving the first cylinder before it.
- The process is repeated until no more cylinders can be driven.
- Finally, a cap is placed on the top of the column and two concrete cylinders are placed on top of the cap.
- When all of the cylinders are driven, hydraulic jacks are placed on the caps and are used to lift the foundation.
- Once the foundation is lifted, steel and concrete spacers are placed on the cap to support the foundation, and the hydraulic jacks are removed.
- The final step is to cover the pilings and clean up.
