Non-Invasive Detection of Corkscrew Pilings Beneath Structure
Non-Invasive Detection of Corkscrew Pilings Beneath Structure
(OP)
Here is the situation:
A 3-story residential structure has been built adjacent to the bank of a river. The plans called for upwards of 80 corkscrew pilings to be driven into the ground to stabilize the foundation. There is a delivery invoice that exists which proves that the pilings were delivered to the property prior to starting construction. However, no documentation exists to 100% prove that these pilings were actually installed. The structure is 10 years old and only minor settling has occurred in this time.
Today, the property is in the process of being sold to a new owner and the question has been asked as to whether or not a non-invasive test exists that could determine if the pilings were truly installed beneath the structure. Can anyone help with this question?
Thanks for any direction you can give and please let me know if I can clarify any information further.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Some have run a dynamic test to estimate the length of pile penetration based on a shock wave and the velocity of that shock wave in the pile and seeing a return echo at the surfce.
