Q:Can helical pilings be attached to my existing foundation
A: The answer is yes, of course your existing foundation must be sound and not failing. Helical piles can be attached to the existing footing which is located at the bottom of your foundation.The helical piles are attached to the footing whenever possible. If the footing is compromised than the helical piles will be attached directly to the foundation. In reality the footing is being replaced with helical piles that are permanently attached to the foundation wall at the footing level.If any leveling of the foundation needs to be done hydrolic jacks are inserted into a specially designed foundation plate that has been secured to the foundation and hydrolic pressure is used to level the foundation permanently.
