Limitations of EM pipe & cable locators
• Only detects metallic targets
or utilities with installed tracer
wires
• Requires a direct connect or
induced current
• Locates a single utility in one
scan
• Accuracy can be compromised
when utilities are closely
spaced due to “bleeding” of
the signal

GPR complements EM technology
GPR detects traditionally non-
locatable subsurface features
including
• Metallic & non-metallic pipes
– PVC
– asbestos cement
– concrete storm and sewer
systems
• Utilities with broken or damaged
tracer wires
• Underground storage tanks
• Drainage tiles
• Non-utility structures
– Vaults
– Foundation walls
– Concrete pads

Additional advantages of GPR
• Can delineate close proximity
utilities
• Provides reliable depth
detection
• Allows for data visualization to
better map the subsurface
• Facilitates reporting and
archiving of results for future
reference

Example: Using GPR to find non-metallic
utilities
• A horizontal directional drilling crew accidentally struck a concrete
storm sewer that had been missed by locators when installing
conduit for fiber.

Example: Using GPR to find non-metallic
utilities
GPR effectively
pin-pointed the
location of the
sewer to prevent
another
expensive fix.

Example: GPR locates utilities in a busy
intersection
A busy intersection needed to be excavated. The number of utilities
made it difficult to get accurate readings from EM locators because of
bleed off.
GPR was used to collect a grid and map all utilities.
It took less than 3 hours to collect the data & get results on-site.

Example: GPR locates utilities in a busy
intersection
GPR mapped all
utilities, metallic and
non-metallic in the
intersection, allowing
for safe excavation.

Example: Locating Underground Storage
Tanks
• A gas station wanted to install additional monitoring wells but did
not have records of the exact perimeter of the underground fuel
storage tanks.
• They used GPR to map the tanks and other buried infrastructure to
ensure safe installation.

Example: Locating Underground Storage
Tanks
GPR successfully mapped the location and depth of underground
storage tanks and feed lines.

Use GPR to make Informed Decisions
• Confirm that you have located
all buried infrastructure
• Identify where it is safe to
excavate
• Document results for future
reference
• Expand your locating service
offerings and make more
money
• Reduce liability and risk with
more thorough locates
