GoliathTech University: Tutorial 16

Is your home showing signs of sinking or settling? Are you starting to see cracks in the brick or concrete? If so, you may want to consider underpinning. This technique strengthens your foundation for better stability for a longer period of time. If you’ve noticed something off with your home, take the time to read this article. We may have the answers for you.


Signs that your house may be sinking include the following:

  • cracks around your basement windows
  • cracks in your brick
  • cracks in the drywall
  • a floor that is no longer level
  • recent water infiltration

If you've identified any of the above, your home is showing that it may have problems with settling or sinking. Depending on the severity, you’ll need to act quick. Underpinning a home is no small task!


If you have any suspicions, the first step is to consult the original plans of your house so that you can discuss them with an expert.

The structural engineer that will work with you will need them to determine the location and maximum loads for the helical (screw) piles. Once you have your plans in hand, you can contact your local GoliathTech certified installer.


With this information, a GoliathTech certified installer will be able to begin the process of excavating around your foundation all the way to your footing in the areas where the piles need to be installed. 

Once the footing is exposed, they will proceed to prepare the footing to receive the underpinning bracket. Our GoliathTech screw piles will then be installed as per the engineered drawing and the bracket will be secured under the foundation footing. Our installer then tensions the bracket with a hydraulic jack to make sure the footing is fully supported.


The final step will be to fill in the excavated areas and call the landscaper. This is the perfect opportunity for new flowers or plants. Keep in mind that the main purpose of the underpinning is to make sure there are no further settlements. Although lifting can sometimes be an option, many risks are associated with this method.

What does a helical pile installation cost for underpinning?

And now the question you are probably asking yourself: what is the cost of underpinning a foundation?

The price to stabilize a foundation depends on the total area needing to be supported, the condition of the soil, the size of your home, and how much it has settled. So don’t wait. The longer you wait after seeing those first signs, the more expensive it will get.
