Wall scanning for
rebar and utilities

Often clients don’t want to compromise the structural integrity of a wall if a core hole or rectangle wall opening is needed. Ground Penetrating Radar can safely and quickly map out those targets so cutting through rebar can be avoided. We can clearly mark out the horizontal rebar and the vertical rebar on walls up to twenty four inches thick. Knowing where the rebar targets are gives you the information you need to make most informed decision on where to cut or core drill.

Post Tension Locating

There is a high probability to cut openings in a new construction build or a renovation construction project. Knowing where post tension cables are located is critical. Ground Penetrating Radar can pinpoint the location and depth of post tension targets. Cutting a post tension cable is very dangerous to anyone in or around the work area. There is a high probability the cable can shoot out the sides of the building or concrete slab and cause great harm to anyone in the path of the cable after it’s cut. These cables can be tension up to 30,000 lbs of tension. Safety first Scan before you cut.


We are able locate reinforcing steel  in concrete structures, parking structures, residential slabs on grade. Using Ground Penetrating Radar we can locate rebar targets and the specific depth of each target. Cutting through rebar unnecessarily can compromise the structural integrity of a structure. We will mark out steel targets and the direction they are running and leave those marked locations clearly marked on the floor for your evaluation.

Determine the
thickness of a concrete slab

Often clients want what’s known as a Concrete Assessment done on their project. We can determine the thickness of a concrete structure and if there are any voids or air gaps in the concrete. Also mapping out the steel spacing and the depths of the steel.
One example of a doing a concrete assessment; a customer wanted to install some hold downs in their post tension  concrete slab and wanted to make sure they didn’t hit any post tension cables. We determined that they were far enough away from any cables and that it was  ok in drilling small 5/8 diameter holes one and half inches deep. Another client wanted to make sure the contractor poured a consistent 6” thick slab on grade specified in his contract.

Conduit Locating

Often conduit is embedded inside concrete slabs and walls. GPR can locate conduit lines and determine the depth of the plastic PVC conduit. If the area looks to complicated with lots of targets,  we can do a 3D Scan to get a better idea of what’s going on below.
Basically the 3D Scan will slice down the concrete Slab in 1/2 increments and can then be viewed in greater detail.
