How Much Does GPR Scanning Cost?
The Scenario
You’ve got a crew ready to core through a slab.
The drill rig is staged. Layout is marked. Everyone is waiting.
But nobody can confirm what’s inside the concrete.
It could be post-tension cable, conduit, rebar, or unknown utilities. One bad core can shut the job down.
That is when GPR scanning needs to happen.
Before you drill. Before coring starts. Before the crew takes the risk.
What Does GPR Scanning Cost?
Most GPR scanning jobs before drilling or coring typically run:
- $995-$1,200 for a half-day mobilization
- $1,800+ for full-day projects
- $200/hr with a 2-hour minimum for quick-hit verification work
- Same-day or next-day mobilization is often available.
Most jobs take:
- 2-6 hours onsite
- with results marked immediately on the slab
What Affects the Price?
Pricing depends on:
- Scan area size
- Slab conditions
- Number of core locations
- Congestion inside the slab
- Site accessibility
- Mobilization urgency
A few cores in an open slab is very different from scanning:
- tight mechanical rooms
- post-tension slabs
- congested conduit zones
- active construction areas with crews waiting
Urgent mobilization can also affect pricing.
What You’re Actually Paying For
You are paying for answers before the drill bit hits concrete.
GPR scanning helps identify:
- Safe drill zones
- Post-tension cables
- Conduit
- Rebar congestion
- Unknown underground targets
You are not paying for a report.
You are paying to avoid:
- damaged PT cable
- conduit strikes
- shutdowns
- delays
- expensive repairs
- injured crews
- rework
811 does not cover this work.
811 does not mark:
- inside slabs
- private interior work
- high-risk drill locations
SiteTwin works where 811 is incomplete or where field verification is still needed before drilling starts.
What Happens On Site
A technician scans the slab live with GPR equipment.
Results are marked directly on the concrete so crews can immediately see what is safe and what needs to move.
You may see:
- paint marks
- drill clearances
- PT cable markings
- conduit identification
- adjusted core locations
Scanning happens live onsite with immediate field markings so crews can make decisions in real time.
Core locations can be verified or moved before drilling begins.
Typical Scheduling
Same-day or next-day mobilization is available in most cases.
Most jobs take 2-6 hours onsite.
Results are marked immediately onsite.
No waiting on a report before the crew can move forward.
When You Need GPR Scanning
You need GPR scanning:
- before drilling
- before coring start
- before anchoring
- before saw cutting
You also need it on: - post-tension slabs
- remodel projects
- interior work
- slab edges
- mechanical rooms
- congested utility areas
GPR scanning is also critical when:
- plans do not match field conditions
- 811 marks do not line up
- work is taking place on private property
- crews are drilling blind into unknown concrete
Don’t Drill Blind
If the crew is ready and anything is unknown, get it scanned before the first hole goes in.
Don’t guess through concrete.
Send the address and scope and get it scheduled.
Keep The Job Moving
Jobsite pressure is real when crews are staged and production is waiting.
But guessing through concrete can shut the job down faster than making the call.
Get the slab scanned, marked, and cleared so the crew can keep moving.
