HOW ARE THEY INSTALLED?

HOW ARE THEY INSTALLED?

The installation process is simple.

  1. 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.
  2. Next, a concrete cylinder is placed in the bottom of a hole and under the foundation.
  3. 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.
  4. 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!
  5. Once a cylinder is driven all the way into the ground, another cylinder is set on top of the first cylinder.
  6. The two steel bars are then cemented into place.
  7. The second cylinder is the pushed into the ground, driving the first cylinder before it.
  8. The process is repeated until no more cylinders can be driven.
  9. Finally, a cap is placed on the top of the column and two concrete cylinders are placed on top of the cap.
  10. When all of the cylinders are driven, hydraulic jacks are placed on the caps and are used to lift the foundation.
  11. Once the foundation is lifted, steel and concrete spacers are placed on the cap to support the foundation, and the hydraulic jacks are removed.
  12. The final step is to cover the pilings and clean up.
