STRUCTURAL

REBAR

Ground Penetrating Radar (GPR) can be used to safely identify metal in rebar slabs. By marking the center of the metal targets, Hard Rock Technologies can lay out multiple layers of patterned metal targets to minimize or completely prevent any compromise of the structural slab.

​GPR is also used on beams, columns, and footings in order to locate the amount of metal targets and layers, the spacing of metal targets, and the concrete coverage.   

DEPTH

Do you need to know if you can safely countersink, score, chip, cut, or anchor in a slab? Hard Rock Technologies can quickly identify the amount of coverage a particular metal target has, within ¼”, before work begins. Ground Penetrating Radar (GPR) allows you to use non-destructive testing methods to know the location and depth of a metal target.

​Hard Rock Technologies has multiple GPR antennas for different locating needs and depths, whether metal targets in slabs, beams, sub-grade, or exterior locations. After locating targets, our technicians can provide depths onsite.

ANOMALIES

Not knowing what's in a slab before cutting can lead to unforeseen conduit repairs and produce added costs and downtime on a jobsite. That's why Ground Penetrating Radar (GPR) is used to safely identify anomalies in and underneath a concrete slab. Hard Rock Technologies uses a variety of tools to identify depth and location of potential conduit to avoid these lurking issues.

After identifying the pattern of a slab, our technician can identify deviations in metal targets or slab construction. GPR allows you to make informed decisions on your project.

POST - TENSION

Do you need to trench in a post-tension slab? Is a sleeve not where it's supposed to be and must now be cut out? Hard Rock Technologies can identify metal in post-tension and pre-tension slabs. Our technicians analyze the spacing and change in depth of the metal, allowing you to safely core or cut without compromising the integrity of the slab.

Hard Rock Technologies has helped customers locate post-tension lines for repair.  In some circumstances the failed cable end has been located so that the customer can fix and re-tension the cable.

METAL - DECKING

There are many types of construction when it comes to metal deck floors. Whether it's Walkerduct or corrugated pan decking in a building, Ground Penetrating Radar (GPR) can be used to locate a safe spot for coring and cutting.

In addition to identifying the high and low troughs of a corrugated metal deck, as well as  anomalies running through the top of the pan, GPR can be used to locate Nelson studs/shear connectors.
