Pilings or structure - check for loose layers of concrete or hollow
spots by sounding with a hammer. A sharp ring noise indicates
sound concrete. A soft surface will be detected, not only by sound
change, but also by a change in the rebound, or feel of the hammer.
A thud or hollow sound indicates a delaminated layer of concrete,
most likely from corrosion of steel reinforcement.

Interior rot by sounding with hammer and probing suspect areas
with a sharp, thin, pointed object. If an area is in question, take a
small boring for laboratory analysis using an increment borer. Once
the core is extracted, seal the hole with a creosote treated plug to
prevent easy access of borers to the interior of the pile
