Which would you rather have at your next project?

GPRS was asked to locate rebar at Long Beach City College. Dowel rods were going to be drilled into existing concrete walls in order to further reinforce the buildings
prior to renovations and modifications.
A well-known testing company had first performed the work with subpar results, then GPRS was hired to redo the project. We used Ground Penetrating Radar to accurately locate both mats of rebar throughout the concrete walls. GPRS marks rebar grids and locations clearly so that you are never left guessing or trying to interpret our markings. We can also use GPR to perform non-destructive testing to locate underground utilities, conduit, post tensioned cables, UST’s, and voids.
