Ground Penetrating Radar (GPR) Powerful, Non-Invasive Technology

• G.P.R. Survey
  • 
    The preferred geophysical survey method for utility investigations; It is used to locate buried lines, storage tanks, pipes and conduits as well as to determine the structural integrity of the ground underneath a road or runway.Click Above for More Info
• Subsurface Utility Engineering
  • 
    The Subsurface Utility Engineering (S.U.E.) Process: We provide QLA S.U.E with nondestructive air vacuum excavation and QLB S.U.E. with a array of geophysical instrumentation; survey grade mapping of data is also performed.Click Above for More Info
• Subsurface Utility Investigation
  • 
    Subsurface Utility Investigation; this non destructive investigation requires multiple types of geophysical survey to be performed, combined with existing drawings (if any) to produce a physical markup on the ground revealing all subsurface utility features in a given area.Click Above for More Info
• Concrete Imaging
  • 
    Concrete imaging is an application used to mark-out position or depth of anything embedded within a concrete structure; these targets include re bar, cables, conduits etc.Click Above for More Info
• Vacuum Excavating
  • 
    Physically exposing utilities with non destructive excavation for the most accurate investigations, Air (hydro also available) vacuum excavation provides QLA subsurface utility engineering (SUE) data; determining the precise vertical, horizontal, size and type of the utility for accurate planning and cross section of the object exposed.Click Above for More Info
• Investigations for H.D.D.
  • 
    Confirming the depth of cover on each crossing practically eliminates the risk of compromising a line. Exact trajectories and depths of installation pathway can be planned in advance.Click Above for More Info

Recognized as one of the most powerful remote sensing geophysical survey instruments available today, ground penetrating radar (GPR) is a safe, non-invasive geophysical investigation method for "looking" underground to image subsurface features. Operating GPR equipment and interpreting its results requires in-depth training and field experience.  Our GPRs are operated by well trained and certified technicians that have prior utility installation experience to boot.

The GPR works by emitting a series of FCC-approved high-frequency, high-amplitude electromagnetic pulses (radio waves) that reflect off of underground irregularities. The resulting digital GPR data is fed into a portable video display which provides a real-time “picture” of a slice of the subsurface area.

AEI's experienced GPR operators use this picture to pinpoint the precise location of subsurface features on the ground surface in real time.

GPR detects metallic and non-metallic, natural and man-made underground features, including: utilities, storage tanks, rebar, sinkholes, voids, water tables, buried artifacts, land mines, shallow ledge and graves which can be applied to a broad range of engineering and environmental applications, including:

• QLB Subsurface Utility Engineering (SUE) 
• Utility Locating and Mapping Subsurface Investigation
• Condition Assessment of Various Diameter Utilities/Drainage Features
• Subsurface Assessments/Encroachments
• Concrete Assessments (rebar spacing, thickness, voids)
• Examination of Structural Integrity
• Bedrock Surface Profiling
• Groundwater Table Mapping
• Conductive Contaminant Plume Mapping
• Shallow Foundation/Footer Locating
