Rebar

No other technology is as reliable, safe, accurate and affordable as Ground Penetrating Radar is for locating rebar inside concrete structures. GPR’s ability to accurately locate reinforcement inside concrete allows for easier concrete cutting and maintains the structural integrity of concrete floors, beams, columns and other concrete structures.

Conduit

The largest role Ground Penetrating Radar serves in the construction industry is its precise ability to locate conduits prior to cutting concrete. Conduits placed in suspended slabs and under concrete floors are present in buildings ranging from supermarkets, to hospitals, to industrial facilities. GPR’s ability to locate these conduits saves building owners tens of thousands of dollars every year.

Tension Cables

The original method of locating tension cables within a concrete deck involved radiography, or x-ray. X-ray is the slowest, most expensive and highest cause for health hazards on a site. Evacuation zones must be established before using radiation to locate cables. GPR has been proven for the past decade to be a faster, cheaper and hazard free way of locating tension cables prior to cutting.

Inspections

Ground Penetrating Radar is able to research a job for any underground unknowns. Able to determine depth of cover analysis for rebar, locate USTs during Phase II investigation or determine the rebar layout for an inspector after the concrete has been poured is all within GPR’s capabilities.

Utilities

Traditional methods of locating utilities involves using locators to “trace out” signals applied to a line. Because these locators are limited to materials that can conduct a signal many utilities cannot be located by traditional means. GPR is capable of locating unknown lines and non-conductive utilities such as clay tile, concrete and PVC lines.

Voids

Eroded soils, sinkholes, caves and underground tunnels are just some of the voids that GPR is capable of locating. Openings at the surface may not reveal what is truly beneath and scanning of the area to assure no other problems exist is becoming and industry standard of safety.

Water Leaks

Radar is commonly known for its ability to track storms as water is a great reflector of radar energy. Ground Penetrating Radar is equally effective in tracking water underground. With an aging infrastructure GPR is frequently called upon to locate leaks underground when not evident on the surface.

Transportation

Both roadways and railways are seeing the benefits that GPR add to the transportation industry. Bridges and roadways benefit from the deterioration and thickness analysis that GPR provides. Railways are able to determine ballast fouling along tracks to identify areas ballast needs to be cleaned.

USTs

Phase II investigations primarily rely upon Ground Penetrating Radar to locate abandoned or unknown Underground Storage Tanks on former gas station sites. Poor record keeping of the past may lead to building owners unaware of the presence of a UST on their site, possibly leaking hazardous petroleum products.

Graves

Unfortunately many graves sites have not been well maintained or old records on paper may have been lost or destroyed. GPR’s ability to look underground is helping thousands of gravesites be re-established throughout the country. The non-invasive method of locating the graves is preferred and deemed more reliable than older techniques such as dowsing.

Geophysical

Looking 100 feet into the ground is a possibility with GPR. Using the lower band frequencies GPR is able to trace out deep subsurface targets such as soil strata, groundwater, bathymetry (underwater sediments) and karst mapping (sinkholes).
