Giles has provided Concrete Imaging Radar (CIR) services to clients on thousands of projects since 2000. We’ve worked for property owners and managers, structural engineers, general contractors, and mechanical, electrical and plumbing contractors. CIR can be used for:
- Locating embedded steel (rebar or mesh), post-tension (PT) cables, and utility conduits
- Detecting rebar patterns and spacing in cast-in-place slabs, beams, and columns
- Estimating concrete thickness and cover distance for embedded steel and PT cables
- Detecting location of PT cables and voids within precast concrete members
- Detecting voids underneath or within slabs
- Locating live electrical lines with the Live Electric Line Detection feature
- Detecting presence of grout and rebar within masonry structures
Whether being used to reduce the chance of cutting embedded items, or to efficiently estimate the depths and pattern of reinforcing steel, or to aid in structural evaluations and repairs — calling Giles for imaging radar services can save you time and money.
Detecting Embedded Obstructions
Build-outs for tenant turnovers are a recurring issue for mall retail and office building property owners, especially when having to relocate openings for new mechanical, electrical, and plumbing lines. Property owners have required installers to have Giles perform CIR to reduce the chance of locating proposed cores and saw cuts over embedded items such as reinforcing steel, post-tension cables, or existing utility lines.
Aging structures require engineers to evaluate conditions and design methods of rehabilitation. We perform CIR to provide critical information regarding the location and spacing of in-place reinforcement, thickness of concrete members, and, depending on site conditions, can detect significant internal delamination. We’ve also performed CIR to aid in evaluating the structural integrity of fire-damaged concrete beams, girders, and elevated deck.
Detecting Voids Under Slabs
A large national retailer’s building suffered a water main break below the slab-on-grade for the sales floor. CIR was used to detect the location and extent of the void caused by the break. Knowing the limits of the affected area allowed the store to quickly perform repairs in a surgical manner, greatly reducing the amount of lost time and allowing the store to re-open far earlier than had been anticipated.
Our experienced technicians can interpret Line Scans to quickly cover large areas.
Grid Scans can provide two-dimensional depth slice images that are similar to those obtained by x-ray method.
