Utility Locating
|
Private utility locating, CAD-based
utility mapping, metallic and non-metallic
utility locating, ahead of construction, utility
route design, verify (correct) public utility
mark-outs.
|
|
UST Locating
|
Delineation of the location, size,
orientation, and depth of metallic or
non-metallic underground storage tanks, septic
tanks, chemical and/or water storage tanks. In
conjunction with Environmental Phase I or Phase
II Investigations, property sales, and
refinancing.
|
|
Soil
Boring & Monitoring Well Utility Clearance
|
Locate and field-mark subsurface
utilities prior to soil boring or monitoring well
creation. We pick up where "One Call"
leaves off!
|
|
Archeological
Projects
|
Non-intrusive delineation of building
foundations, trash pits, artifacts, graves and
burial plots. Historic cemetery mapping.
|
|
Expert
Witness Testimony
|
Geo-Graf is experienced in providing
expert witness testimony regarding subsurface
investigations and use of geophysical delineating
techinques. Utility right-of-way disputes,
excavating accidents, mis-marked or unlocated
utilities, tanks, etc.
|
|
Structural
Analysis
|
We'll use GPR to safely and effectively
scan concrete floors or walls to delineate
thicknesses, reinforcing position and frequency,
voids, gaps, or sub base settlements.
Post-tension cable locating, embeded conduit and
utility locating.
|
|
Sinkhole
Delineation
|
Map
the extent of subsidences, sinkholes, and voids.
Delineate sources or causes. Provide data for
remediative efforts. Annual inspection programs
for sinkhole prone sites.
|
|
| Geological
Feature Mapping |
We'll use GPR to determine
depth to near-surface consolidated rock, generate
actual continuous bedrock profiles without data
extrapolation. Ahead of construction or utility
installations |
|
| Pipeline
Leak Detection |
We'll use GPR to
locate water, natural gas, oil, or sewage leaks.
Also analyze subsoil impact of the discharge:
impacted subsoil boundary, resulting washouts or
void areas, plume field delineation. |
|
| Landfill
Surveys |
Delineate the
extent of buried metallic debris, buried drums,
trash ahead of construction or property sales.
Generate landfill capping thickness profiles. |
