Concrete scanning

Non-destructive concrete scanning to locate reinforcement, measure concrete cover and support structural assessments.

Rebar location and concrete cover
Bar diameter and layout mapping
On-site scanning and marking
Scan reports and engineering interpretation

Newground Projects uses the Hilti PS 300 Ferroscan electromagnetic concrete scanner to locate reinforcement, measure concrete cover and estimate bar size for structural analysis. Scanning is non-destructive: no coring or breaking out is needed. The system uses no ionising radiation and can be used in occupied buildings.

Capabilities

Detection of steel objects up to 200 mm deep, with locating accuracy of 1% ±3 mm
Measuring concrete cover to reinforcement
Estimating reinforcing bar diameter
Mapping bar layout and spacing, including bars as close as 30 mm apart
On-screen plan and section views of the rebar layout for immediate analysis on site
Scanning large areas, with data recorded for documentation and structural analysis

Applications

Safe drilling, coring and anchor installation: confirming rebar-free zones before penetrations
Tenant fit-outs and alterations: checking reinforcement before fixings, openings or post-installed anchors
Concrete repair and durability work: checking cover across large areas and mapping low-cover zones linked to spalling and corrosion damage
Structural assessments: confirming reinforcement where drawings are missing, incomplete or unreliable
Quality control and as-built verification: building acceptance inspections and checking constructed work against design drawings

Services offered

On-site scanning, with reinforcement positions marked directly on the concrete
Scan reports with plan and section views, cover and bar-size data, and statistics
Interpretation by a chartered structural engineer in the context of the structure’s design and condition
Recommendations for further investigation where needed
Ongoing scanning agreements for property owners and facilities managers with recurring needs

What scanning can tell you

The scanner shows where steel is and how deep it sits. It cannot confirm corrosion, loss of steel section or the condition of pre-stressing. Where condition matters, scan results help target destructive investigation, such as break-outs or cores, so that it is focused, minimal and cost-effective.

Pricing

Pricing is project-specific. For ongoing requirements, rate schedule agreements offer fixed tiered rates over a multi-year term, reviewed annually.

Complexity: five scanning tiers based on access, reinforcement congestion, member type and site constraints
Site time: time spent scanning on site
Reporting: tiered fees according to the level of reporting and engineering interpretation required
Travel: charged for sites outside the East London area
