We can see into concrete before drilling, cutting or coring: Rebar placement, depth, position, Rebar inspection, Slab thickness, Inspect walls, floors, decks, slabs, tunnels, balconies and garages, Post tension mapping, Concrete, asphalt, masonry block, grouted cells, ICF foam.

Locate longitude and transverse rebar for angled 48` core locations for epoxy rehab. Locate Vertical Steel within girder walls for core locations. Beam strengthening, access holes, drainage locations. Mapping Interior/Exterior faces of curtain walls, box girders, beams, hanches, hammer-heads for retrofits.

GPR DATA INC. provides bridge deck condition assessment and analysis, bridge deck inspection and bridge testing using various combinations of Ground Penetrating Radar (GPR) air-coupled or ground-coupled antennas, and/or Infrared (IR) cameras, even at highway speeds. Lane closures are rarely required, traffic isn’t interrupted, and personnel aren’t exposed to hazards.

Detailed investigation of any available records, plans, and maps, Field staking of the exact location of the proposed features in possible conflict with existing utilities, Location of existing buried utilities or any other structures, Non-destructive excavation test hole to expose the utility at all points of possible conflict, Restoration of the test hole and marking of the location utilitizing established utility designating color codes and ASCE Standards of Practice, Formal Report and Inventory, detailing all ground proofs, subsurface features, and utilities found, Station survey of the test hole locations for CADD mapping of project site.

GPR Data Inc. pioneered the use of ground penetrating radar to create As Built documentation for existing construction.

GPR DATA INC. provides non-destructive evaluations of pipelines, aqueducts, drainage pipes, chemical process piping, closed loop systems, and other buried product feed or product return pipelines. GPR DATA INC. can identify areas in need of repair with technologies including Ground microwave Penetrating Radar (GPR), Infrared Thermography (IR), and Impact-echo (IE). Our services are not limited to depth of concrete, depth of burial, or pipeline composition. Our state of the art technologies provide high resolution information on piping composed of concrete, HDPE, transite, steel, ductile iron, PVC, and cast iron, in nature.

GPR Data Inc. was called in to investigate this sinkhole in December 2007, but what we discovered was not what anyone expected. The sinkhole had been completely attributed to raw volume of water traveling through a drainage pipe. However, upon investigation with ground penetrating radar, we determined that three underground storage tanks had been buried and forgotten, in close poximity to the sinkhole. At least one of the tank walls had been destroyed by electrolysis, creating an open void which allowed sub-surface evacuation of the subgrade structure.
