Abstract:
A method and system are provided for detecting a void in backfill material such as soil surrounding a buried conduit such as a pipeline. The void is detected by monitoring an acoustic response from the conduit in response to acoustic excitation of the interior of the conduit. An analysis of changes in the acoustic response is then related to the presence or absence of a void in the backfill material.
