Highway and Bridge Structures

The strategic road network is the backbone of national infrastructure, yet it faces a perfect storm of challenges. Decades of heavy traffic loading, freeze-thaw cycles and the aggressive use of de-icing salts have accelerated the deterioration of concrete and masonry assets.

 

Structural Repairs & Traffic Management

The strategic road network is the backbone of national infrastructure, yet it faces a perfect storm of challenges. Decades of heavy traffic loading, freeze-thaw cycles and the aggressive use of de-icing salts have accelerated the deterioration of concrete and masonry assets.

Structural Repairs provides specialist engineering support to Highway Authorities, Concessionaires and Tier 1 Contractors worldwide. From the routine maintenance of reinforced concrete bridges to complex emergency works following vehicle impact, our mission is simple: extend the life of the asset while minimising disruption to the road user.

We move fast to reduce your Traffic Management (TM) spend, utilising agile teams and rapid-setting technologies to complete critical repairs during tight engineering windows or overnight closures.

Innovation: Engineering the Solution

In the highways sector, “time is money” is literal—lane rental charges and TM costs often exceed the value of the repair itself. We innovate to reduce your time on site.

  • Rapid-Cure Deck Repairs: We utilise specialist fast-setting mortars and resins that achieve full structural strength in as little as two hours. This allows us to cut out, repair and reinstate a bridge deck within a single overnight shift, ensuring the road reopens for the morning rush hour without penalties.
  • Composite Impact Solutions: When bridges are struck by over-height vehicles, demolition is often the default fear. We have pioneered the use of high-modulus Carbon Fibre (CFRP) laminates to restore lost tensile strength to damaged beams. This solution is non-intrusive, adds negligible weight and can often be applied from mobile access platforms, avoiding long-term road closures.

Environmental Jeopardy & Carbon Efficiency

The Chloride Threat The greatest environmental jeopardy for highway structures is hidden. Years of winter de-icing have saturated thousands of bridges with chloride ions, triggering aggressive reinforcement corrosion. If left unchecked, this leads to structural deficiency and, ultimately, the need for carbon-intensive demolition.

The Low-Carbon Life Extension

A full bridge replacement is a carbon disaster, generating massive demolition waste and requiring the casting of hundreds of tonnes of new concrete. We offer a sustainable, “repair first” alternative that drastically reduces embodied carbon, aligning with the sustainability guidelines set by the Institution of Structural Engineers (IStructE).

Cathodic Protection (CP)

By installing a sacrificial anode system or an Impressed Current Cathodic Protection (ICCP) system, we can electrically halt the corrosion process. This saves the existing concrete and steel, extending the structure’s life by 25+ years for a fraction of the embodied carbon of replacement.

Hydro-Demolition

We use precision high-pressure water jetting to remove only the defective concrete, leaving the healthy structure and rebar intact. This minimises waste generation and eliminates the micro-cracking associated with mechanical jackhammering.

Concrete Bridges & Viaducts

Culverts & Retaining Walls

  • Culvert Strengthening: Installation of GRP liners or structural spray concrete to rehabilitate failing drainage structures without excavation.
  • Ground Anchoring: Stabilisation of wing walls and retaining structures using soil nails and ground anchors to permanently arrest ground movement.

Bridge Bearings & Joints

  • Bearing Replacement: Design and installation of temporary propping and hydraulic jacking systems to unload bridge decks, allowing for the replacement of seized or failed bearings.
  • Expansion Joint Remediation: Repair and replacement of buried and mechanical joints to prevent salt water leaking onto the substructure—a primary cause of pier corrosion.

Gantries & Signage Supports

  • Foundation Repair: Strengthening of concrete bases and plinths for overhead gantries.
  • Protective Coatings: Application of anti-carbonation coatings to extend the durability of exposed concrete elements.

Inspection, Survey & NDT

We provide the data you need to make informed Asset Management decisions.

  • Bridge Deck Inspections: Testing for chloride content, carbonation depth and half-cell potential mapping to predict remaining service life.
  • GPR Scanning: Non-destructive location of tendons, rebar and voids within post-tensioned structures.
  • Cover Meter Surveys: Verifying concrete cover depth to ensure compliance with design standards.
