Ground Penetrating Radar Applications
Water, Gas, buried Electric, Sewer? What's under here?
The more that you know
about the subsurface of your project
the safer it will be to excavate.
While not everything can
be identified by GPR (some soils can obscure
features), we can usually define the trench
where they are buried. Some
applications are presented here.
Directional drilling - guiding the drilling bit, in real-time, for ledge avoidance.
Scanning the subsurface of a brook.
Directional
drilling. This project required that we locate a path through wetlands
and directly under a brook. Conservation restrictions prevented wetlands
excavation.
A GSSI 400Mhz antenna, configured to scan under the brook, was
able to
locate a path that would allow the drill bit to cross under the
brook at
the required depth of 4 feet.
Where's the buried tank?
A concrete pad needed
to be installed for an emergency generator
at this Public Works building.
They knew that there was a buried
holding tank under the pavement, but
where? GPR scans revealed
not one but two buried tanks.
