Scanning Before the Saw

Modern concrete structures are rarely just concrete; they rely heavily on internal reinforced steel, most often present in the form of rebar or post-tension cables, which are used to strengthen and support the material in tension. Maintaining these components is critical when ensuring the structural integrity of a building.

To safeguard assets like these, Chesco utilizes Ground Penetrating Radar (GPR) as a mandatory diagnostic protocol before any invasive work begins. This technology operates by transmitting mid-range electromagnetic (EM) waves (400–1600 MHz) through the material and recording the return time of reflected signals, then translating them into accurate depths from the surface. 

Chesco’s advanced equipment can locate hidden embedded targets—including structural steel, conduits, voids, and existing utilities—at depths between 1-10 feet in concrete structures and slabs.

Striking these hazards blind can critically damage expensive diamond-bladed equipment and cause severe damage to the building’s underlying stability. To prevent this, our technicians deliver high-resolution information in real time, with post-processing capabilities that provide clear 2D and 3D perspectives of the subsurface landscape.

Where Speed Meets Precision

Once GPR scanning securely maps the internal layout of the slab, Chesco deploys advanced high-cycle electric and hydraulic powered equipment for the physical modifications. We use specialized diamond blades and bits to create exact openings in concrete floors and walls for building expansions, electrical conduits, HVAC installations, and utility infrastructure.

By pairing high-tech utility locating with high-performance cutting machinery, our technicians know precisely what lies inside the slab before the first cut is made. This allows our crews to slice through complex materials and mass concrete components of virtually unlimited thickness, including solid steel encasements and heavy rebar cages, without triggering dangerous structural strikes or unexpected work stoppages.

This calculated approach makes sure we have exact dimensions while minimizing operational downtime for the facility.

The ‘After-Action’ Promise

Accurate GPR scanning acts as the initial line of defense against job site messes so that crews don’t accidentally strike live water mains, gas lines, or electrical lines. 

During the subsequent cutting and grinding phases, Chesco enforces strict clean-site protocols. We use wet cutting techniques paired with industrial shop vacuums to immediately contain and collect water and the resulting concrete slurry. For sensitive indoor spaces, we implement dry cutting paired with specialized HEPA filter systems to capture hazardous silica dust at the source.

Once the concrete is separated, our Rigging & Removal service takes over. Our team manages the heavy extraction and hauling logistics to safely lift and clear the multi-ton payload from the area, leaving you with a clean, pristine, and work-ready environment.
