Starting a concrete scanning business requires a GPR unit ($15,000–$40,000 for entry-level equipment like GSSI or Proceq), training or certification in subsurface imaging, general liability insurance, and a way to manage scheduling, quoting, and reporting from day one. Most operators start solo, running 3–5 scans per day from a single vehicle, and grow to a small crew within the first two years if they can build a reliable GC referral base.

Concrete scanning is one of the faster-growing niches in field service. Construction activity drives demand — every time a GC needs to core, cut, or anchor into an existing slab, they need someone to scan it first. Post-tension cables, embedded conduits, and rebar all create risk, and the cost of hitting one (structural damage, injury, project delays) makes the $300–$500 scan fee look like cheap insurance. The barrier to entry is moderate — the equipment is expensive, but the operating costs are low once you're set up.

Equipment you need (and what it costs)

GPR unit

This is your primary tool. Ground-penetrating radar sends radio waves into the concrete and reads the reflections to identify embedded objects. The two dominant brands in structural scanning are GSSI (StructureScan Mini XT, StructureScan Pro) and Proceq (GP8000, GP8800).

• Entry-level — GSSI StructureScan Mini XT: $15,000–$20,000. The workhorse of the industry. Single antenna, handheld, good for most clearance scanning and slab work. This is what most new operators start with.
• Mid-range — Proceq GP8000: $20,000–$30,000. Stepped-frequency radar with 3D imaging capability. Better target resolution than entry-level units.
• Full-featured — GSSI StructureScan Pro: $30,000–$40,000. Multi-antenna system for larger survey areas. Faster data collection on full-floor surveys.

Start with a single entry-level unit. You can add a second unit or upgrade to a multi-antenna system once you have steady revenue. Buying used equipment is an option — GPR units hold their value well, and a used GSSI Mini XT in good condition runs $8,000–$12,000.

Supporting equipment

• Marking supplies — paint sticks, marking paint, and caution tape. Budget $50–$100/month.
• Measuring tools — tape measures, laser distance meters, and a chalk line for marking scan grids.
• Tablet or phone — for report generation in the field. Any modern smartphone works.
• Vehicle — GPR equipment fits in any SUV, truck, or van. No special vehicle required.

Training and certifications

GPR isn't a tool you can pick up and start using productively without training. Interpreting radar data — distinguishing rebar from conduit, identifying post-tension cables, recognizing signal artifacts — takes practice and instruction.

• Manufacturer training — GSSI and Proceq both offer training courses (typically 2–3 days, $1,500–$3,000) that cover equipment operation and basic data interpretation. Start here.
• CFLHD/AASHTO certification — not required in most jurisdictions, but adds credibility. Some government and large commercial projects require certified operators.
• On-the-job experience — the most important training. After formal instruction, plan on 50–100 scans before you're consistently confident in your interpretations. Consider working for an established scanning company for 6–12 months before starting your own operation.

Insurance and licensing requirements

• General liability (GL) insurance — required. A minimum of $1 million per occurrence/$2 million aggregate is standard. Many GCs require $2 million per occurrence as a condition of working on their sites. Budget $1,500–$3,000/year for a solo operator.
• Professional errors and omissions (E&O) insurance — strongly recommended. This covers you if a scan result turns out to be wrong and causes damage. E&O premiums for concrete scanners run $2,000–$5,000/year.
• Business license — standard local business license. Requirements vary by municipality.
• Vehicle insurance — commercial auto if you're using a vehicle for business. Your personal auto policy likely doesn't cover commercial use.

How to get your first GC clients

Concrete scanning is a B2B business. Your clients are general contractors, structural engineers, coring companies, and occasionally property managers or building owners. You don't advertise on yard signs or door hangers. You build relationships with the people who need scans on a regular basis.

• Visit active job sites — drive to commercial construction sites, introduce yourself to the superintendent, and leave a card. GCs who are currently renovating existing buildings need scanning services regularly. The in-person approach works because scanning is a trust-based service — GCs want to know the person clearing their slabs.
• Partner with coring companies — coring contractors need scanning before every job. Many don't own GPR equipment. A partnership where you provide the scan and they provide the core is a natural fit and creates a recurring referral loop.
• Offer a free first scan — to demonstrate your turnaround speed and report quality. If the GC has been waiting two days for reports from their current scanner and you deliver same-day, you've won a client.
• Google Business Profile — set up and optimize your GBP with "concrete scanning" and "GPR scanning" as primary categories. Many GCs search Google when they need a scanner in a new area.

Setting up your scheduling and reporting workflow

From day one, you need a system for managing job requests, scheduling scans, delivering reports, and tracking payments. A spreadsheet works for the first month. After that, you'll need field service software.

Here's what your workflow looks like with Clevra:

• GC calls or emails with a scan request — you create a job with the project details, site address, and contact info. Quote goes out from your phone in under two minutes.
• Quote accepted — job moves from your sales pipeline to your schedule. You assign it to a time slot based on location — batch nearby jobs to minimize drive time.
• On site — you perform the scan, fill in findings on a mobile work form (scan area, depth readings, target types, recommendations), attach photos, and generate a branded PDF report.
• Report delivered — emailed to the GC before you leave the site. Same-day turnaround, every time.
• Invoice sent — invoice generated from the job record. GC pays online or by card. Payment syncs to your accounting software.

Clevra's free plan covers a solo operator's full workflow — scheduling, quoting, invoicing, and reporting — from day one. No software cost until you add crew.

FAQ

How much does it cost to start a concrete scanning business?

Plan for $20,000–$50,000 in startup costs. The biggest expense is GPR equipment ($15,000–$40,000). Add $3,000–$5,000 for insurance (GL + E&O), $1,500–$3,000 for training, and $500–$1,000 for marking supplies, measuring tools, and business setup. Many operators start with a used GPR unit to reduce the initial investment to under $20,000.

How much can a concrete scanner make per year?

A solo operator running 3–5 scans per day at an average of $400 per scan can gross $250,000–$500,000 per year. Net margins after equipment, insurance, fuel, and operating costs typically run 40–60% for a solo operator. Income scales with volume and with the addition of higher-value full-floor surveys ($1,000–$5,000+ per project).

Do I need certification to do concrete scanning?

In most US and Canadian jurisdictions, no formal certification is legally required. However, manufacturer training (GSSI or Proceq) is practically essential for accurate data interpretation. Some government and large commercial projects require certified operators. Getting trained and building a track record of accurate scans is more important than any certificate.

How do I find concrete scanning clients?

Visit active construction and renovation sites, introduce yourself to GC superintendents, partner with coring companies who need scan services, set up a Google Business Profile, and focus on same-day report delivery as your competitive advantage. Concrete scanning is a referral business — one happy GC leads to five more.

What's the best GPR unit for a startup?

The GSSI StructureScan Mini XT is the most popular entry-level choice at $15,000–$20,000. It's reliable, widely used in the industry, and has strong manufacturer support and training. Start with this unit, learn the trade, and upgrade to a multi-antenna system once you have steady revenue and want to take on full-floor survey projects.
