Subsurface intelligence for construction

See through concrete — before you dig, cut, or drill.

See Thru Concrete maps hidden infrastructure inside concrete, underground, and above ceilings so construction teams can understand existing conditions before work begins.

Existing conditions

Know what's there before you build.

Construction teams often make decisions based on incomplete or outdated information about what exists underground or inside a structure.

See Thru Concrete provides a way to understand those hidden conditions before crews dig, drill, cut, or renovate.

Applications

One scan. Multiple layers of information.

One pass over a slab, wall, or ceiling returns a structured record — what sits behind the surface, and what condition it is in.

Raw scan in. Live cross-section out.

The dashboard turns scan returns into a live cross-section, classifying rebar, conduit, pipes, voids, and moisture pockets — each with its own confidence score.

Process

From site scan to usable information.

01 — Scan

Capture the area being investigated — slab, wall, or ceiling — in a single pass.

02 — Detect

Identify hidden structures and objects behind the surface.

03 — Map

Convert the information into a structured 3D representation.

04 — Plan

Use the information to make better construction decisions.

Technology

Built on a different sensing approach.

Patented low-frequency coherent field sensing images below grade and inside concrete — detecting objects and structures up to 6 feet into the ground or through concrete with significantly lower power and simpler hardware than conventional ground-penetrating radar.

Measurement

Finding the steel is not the same as measuring it.

Radar can tell you a bar is there. It cannot tell you how thick it is. Diameter is what gives an engineer area of steel, and area of steel is the input every capacity calculation turns on.

On a corroded bar, the same measurement returns remaining section — how much steel is still carrying load. That is the number that decides whether a structure retains the capacity it was designed for, and today it is obtained only by breaking the concrete open.

Method Returns Where it stops
Ground-penetrating radar
ReturnsBar location, spacing and cover
Where it stopsCannot size the bar, so it cannot give area of steel or remaining section.
Half-cell potential
ReturnsThe probability that corrosion is active
Where it stopsA probability, not a quantity. It says corrosion is likely somewhere, not how much steel is left.
Polarisation resistance
ReturnsAn instantaneous corrosion rate
Where it stopsA spot reading of rate, not of the loss that has already accumulated.
Breaking out and measuring the bar
ReturnsRemaining section, definitively
Where it stopsDestructive, slow, samples a handful of locations and damages the element it measures.
See Thru Concrete
ReturnsBar geometry and remaining section, across the whole element
Where it stopsNot bar grade and not compressive strength. Those still need a sample.

We do not claim bar grade or concrete compressive strength. Neither is obtainable without a physical sample, and any method that says otherwise is worth questioning.

Why it matters

Better information before the work starts.

Retrofit instead of rebuild

Measure the reinforcement that is actually in the building, so an upgrade is designed against real capacity rather than a conservative assumption that pushes an owner toward demolition.

Inspect without closing

No lane closure, no ward decanted, no berth taken out of service, no facade dismantled. The scan fits the operating window you already have.

Every element, not a sample

Coring forces you to open a few and infer the rest. Full coverage changes what an inspection report is able to assert.

See the rate of loss

Because nothing is damaged, the same element can be rescanned next cycle. Two readings turn a condition report into a forecast.

Who it's for

Built for the people who own the risk, not the schedule.

01

Healthcare systems

California acute care buildings must be capable of staying operational after an earthquake by 2030, and the upgrade path depends on knowing what reinforcement is actually in the building. Measuring it rather than assuming it is often what makes a retrofit viable instead of a rebuild.

02

Airports and ports

Decks, aprons, wharves and piles that cannot be closed in order to be inspected, sitting in the chloride exposure that attacks them fastest. Scan inside the operating window you already have.

03

Bridges, highways and transit

Delamination and corroding reinforcement start inside the slab and reach the surface late. Find them without a lane closure or a track outage, across every element rather than the few you could afford to core.

04

Parking structures

The most chloride-loaded concrete anyone owns. Vehicles carry brine directly onto the deck where it ponds, and post-tension corrosion stays invisible until it is not.

05

Universities and campuses

Decades of deferred maintenance with no way to rank it except by what has become visible. Turn a backlog into a capital plan backed by measurements.

06

Structural and forensic engineers

You carry the liability and you write the inspection scope. Cut destructive openings from hundreds to a handful, and raise the knowledge factor your evaluation depends on.

Existing structures

Maintaining a structure means knowing what is actually inside it.

Bridges, hospitals, garages, and towers get inspected on a schedule and repaired on a budget. Both decisions rest on the condition of concrete poured decades ago, covered since, and never opened.

Scanning gives the owner that picture without taking the structure apart.

Section · deck slab, delamination01

Bridges and transport structures

Decks, piers, and abutments carry load through concrete that freezes, thaws, and takes de-icing salt every winter. Delamination and corroding reinforcement begin inside the slab and reach the surface late, well after a cheap repair stopped being an option.

Inspected today by

Chain drag and hammer sounding for hollow areas, cores pulled for testing, and a lane closure to do either.

Section · column, crack through cover02

Seismic upgrades and healthcare

When the reinforcement inside an existing building is unknown, the engineer has to assume conservatively. Conservative assumptions make a building calculate worse than it is, and a building that calculates badly gets recommended for replacement.

Measuring the steel that is actually there lets the retrofit be designed against real capacity. That is often the difference between upgrading a building and demolishing it.

Inspected today by

Selective demolition and destructive testing, scheduled around wards that cannot close.

Section · clad column, corrosion behind panel03

Buildings and facades

Owners carry a standing duty to keep columns, facades, and structure safe for as long as they hold the asset. Cladding and finishes cover the elements that fail, so deterioration gets found on a sample and the rest of the building is inferred.

Inspected today by

Removing panels, or drilling a small hole and feeding in a borescope, then reinstating the facade.

Nothing opened
No coring, no panel removal, no selective demolition, nothing to make good afterwards.
Nothing damaged
The element is left exactly as it was found. Nothing is weakened by the inspection itself.
No exclusion zone
A low-frequency field drawing a few hundred watts, so work carries on around the operator.
As built, not as drawn
Density, voids, and cracking in the element you actually have.
Every element
Not a cored sample and a statistical inference about the rest.
Trended over time
The same element rescanned each cycle, so you see the rate of change.
