Underground measurement without excavation

For one of our projects, we need to measure the size of several existing underground foundations and piles without excavation. If anybody knows any measurement technique such as using Ultrasonic Wave of any similar technique that can help us, please contact me or send me the contact information: bardiae@SITE-Blauvelt.com


Thanks,

Bardia

Re: Underground measurement without excavation Bardia,
Are the pile heads (or shaft near head) and foundation surface accessible?
if yes:
- piles: low strain pile integrity testing for length, if high accuracy is needed, use parallel seismics.
- slabs: ultrasonics. Special equipment needed, we use Russian shear wave point contact devices.

if no: no way.

Supply details, if more information needed. Questions welcome.

Best regards, Ernst
