GPR rebar grid chalk markings on concrete slab - Nashville Yards
Concrete Scanning

Concrete Scan — Rebar Grid

Full rebar grid mapped across a large concrete slab at Nashville Yards. Black chalk marks show every rebar member — spacing, depth, and direction — giving the drill crew a precise guide before any penetrations were made.

Scope: Full-slab rebar grid scan

TRUSTED BY
NASHVILLE'S
BEST CREWS

01
99% Detection Accuracy

Our GPR equipment and interpretation protocols consistently identify rebar, conduits, and tension cables — even in thick or congested slabs.

02
Reports in 24 Hours

You get a full PDF drill guide or utility report delivered the next day — so your schedule doesn't slip waiting on data.

03
On-Site Chalk Markings

We mark every finding directly on the slab with color-coded chalk so your driller has clear guidance at the hole — not just on paper.

04
$500–$2,000 vs. $50,000+

A scan costs a fraction of what a hit cable, broken conduit, or cut rebar costs. One job saved pays for years of scanning.

AVERAGE DAMAGE COST BY TYPE
Hit Post-Tension Cable $40–$80K
Cut Electrical Conduit $15–$30K
Damaged Water Line $10–$25K
Rebar Breach + Delay $5–$15K
GRT Scan Cost $500–$2K

FREQUENTLY
ASKED

How much does GPR concrete scanning cost in Nashville?

Scanning starts at $500 and typically runs $500–$2,000 per project depending on the number of areas and site complexity. That's a fraction of the $10,000–$80,000 in damage costs if a post-tension cable, conduit, or rebar is struck during drilling.

How quickly do you deliver scan reports?

We deliver a full PDF drill guide or utility locating report within 24 hours of the on-site scan — so your schedule doesn't slip waiting on data.

Can GPR detect post-tension cables in concrete?

Yes. GPR is highly effective at locating post-tension cables, rebar, electrical conduits, and voids in concrete slabs. Our equipment achieves 99% detection accuracy and every finding is marked on-site with color-coded chalk.

What areas in Tennessee do you serve?

We serve the full greater Nashville metro — Downtown, Midtown/West End, Brentwood, Franklin, Murfreesboro, Hendersonville, and Antioch — as well as Chattanooga, TN. Out-of-market projects available; contact us for travel rates.

What is APWA color coding for utility locating?

APWA (American Public Works Association) color codes standardize how underground utilities are marked: Yellow = Gas, Red = Electric, Blue = Water, Orange = Telecom, Green = Sewer, Pink = Unknown. All GRT utility reports follow these standards.
