Where it is used

Different structures. Same question: what's inside?

Most concrete inspection challenges look different on the surface, but share the same underlying problem: you cannot see what is happening inside. Elop Insight addresses that across a wide range of asset types.

Concrete bridge structure

Bridges

Bridge decks are exposed to traffic loads, de-icing salt and weather year-round. Chloride penetration and reinforcement corrosion are the leading causes of deterioration, which is why periodic condition assessment is standard practice on most bridge maintenance programmes. While these are often limited to visual inspections, additional NDT approach will provide considerably more knowledge to act on.

Delamination
Tendon duct voids
Grouting defects
Thickness variation
Concrete tunnel

Tunnels

Tunnel linings carry significant load while holding back groundwater and earth pressure. Incomplete grouting, poor concrete consolidation during construction, and long-term water exposure are common causes of deterioration — making periodic condition assessment important even when the lining shows no visible signs of distress.

Voids behind lining
Debonding
Grouting defects
Layer separation
Parking garage

Parking

Vehicles track in de-icing salt throughout winter, and in an enclosed structure that chloride-laden moisture has limited opportunity to drain or evaporate. Chloride-induced corrosion is the dominant deterioration mechanism in parking structures, which is why regular condition monitoring and inspection is recommended regardless of the structure's age.

Industrial concrete floor

Buildings and floor slabs

Floor slabs in warehouses and industrial buildings carry heavy, repeated loads — forklifts, racking, stored goods. On new builds, that means verifying the slab was cast correctly before it's put into use. On older ones, years of traffic can cause cracking, wear and loss of subgrade support. Either way, the defects that matter most usually aren't visible from above.

Concrete dam

Dams and hydraulic structures

Concrete dams and hydraulic structures are subject to sustained water pressure, freeze-thaw cycling and decades of structural loading. Given the long service life and safety implications of these structures, systematic long-term inspection programmes including NDT allows for better condition assesment, maintenence planning and repairs for safe and productive operation.

Thickness assessment
Nuclear facility cooling tower

Nuclear and offshore facilities

Concrete containment structures and offshore platforms are designed and built to unusually tight tolerances, where even minor construction-related defects can be significant relative to the consequences involved. This is why inspection regimes for these structures tend to be among the most rigorous ones. Non-destructive methods are implemented on elements like tendon ducts where defects aren't visible from the surface.

Inspection workflow

Efficient quality control for large areas

Ultrasonic pulse velocity testing is a proven non-destructive method for evaluating concrete quality and strength, but traditional probes are slow and limited for large-area inspections. The Insight scanner improves this by enabling fast, quantitative rolling ultrasonic scans over large surfaces using multiple wave modes to map velocity and estimate strength-related properties like dynamic elastic modulus.

This allows rapid identification of low-quality zones, targeted follow-up with 3D tomography, and a major reduction in time, cost and the need for destructive core drilling.

Inspection workflow

Inspect for accurate concrete thickness

Is your concrete slab or wall built to the correct thickness? Even small deviations can compromise structural integrity and safety. Our Insight scanner provides a definitive answer without destructive coring.

While confirming thickness, the scan also maps embedded objects and internal voids, ensuring a complete quality assessment of the as-built structure.

What we detect

Multiple defect types.
One scan.

The same rolling pass that covers the surface captures data on all detectable defect types simultaneously, with no separate setup for each finding.

Delamination

A subsurface separation that occurs horizontally within the concrete slab, splitting the concrete into internal layers. Typically caused by corrosion of internal steel rebar.

Debonding

The separation of two different concrete placements or materials where they meet. This happens when a new concrete overlay or repair mortar fails to stick to the existing, hardened base concrete.

Honeycombing

Areas of the concrete where the fine mortar failed to fill the spaces between the coarse aggregate stones, leaving a cluster of empty air pockets.

Tendon ducts

Location and condition assessment of post-tensioning ducts in concrete structures.

Air pockets

Trapped air inclusions that reduce the compressive strength of the concrete. Large voids mean there is less solid mass to carry the weight.

Grouting defects

Incomplete grouting in tendon ducts - a leading cause of corrosion in post-tensioned structures.

Fiber reinforcement

Imaging and quality control of fiber-reinforced concrete elements and SFRC slabs.

Thickness and backwall

Accurate thickness measurement and backwall detection across the full scan area.

Common questions

Things people usually ask us.

Does it work on all concrete surfaces?

Elop Insight works on most horizontal and near-horizontal concrete surfaces. Very uneven or heavily textured surfaces may require assessment, so contact us to discuss the specific structure.

How deep can it detect defects?

At a 100 kHz centre frequency, Elop Insight can typically detect defects at depths between 50 mm and 1000 mm, depending on concrete quality and defect type. Under favorable conditions, thickness measurements, defects and anomalies may be detected at depths of up to 2000 mm.

Does the structure need to be taken out of service?

Not necessarily. Because the scanner requires no drilling, gel, or access to both sides of the structure, inspections can often be carried out while assets remain in partial or full operation.

Can I compare results from different inspection dates?

Yes. The Elop Insight Portal stores scan data from inspection sessions so teams can compare 3D results over time and track whether defects have grown, stabilised, or been repaired.

Do I need gel or liquid couplant to scan?

No. Elop Insight uses patented dry-coupled rolling transducers, so no gel, water, or other coupling agent is needed. This is a major practical advantage: less mess, no surface preparation with couplant, and continuous scanning without stopping to reapply.
