Expansion joints maintenance

As a dedicated specialist in bridge structural component maintenance, Bridgent supports infrastructure owners in systematically inspecting, evaluating, and rehabilitating deteriorated roadway expansion joints. Our interventions restore full traffic safety for highway and motorway operators while minimising service disruption

Scheduled or emergency maintenance of expansion joints becomes necessary in a range of scenarios:

●Planned maintenance activities carried out under long-term asset management agreements

●Rapid-response emergency repairs to promptly reinstate carriageway safety

●Combined interventions coordinated alongside other road works, such as pavement resurfacing programmes
—KEY CONSIDERATIONS
Expansion joints challenges
A deteriorated roadway expansion joint creates hazardous conditions for road users and demands prompt preventive action. Bridgent recommends systematic periodic inspections and immediate remediation whenever a defective element is detected. Exposed to heavy goods vehicles, high traffic volumes, extreme weather cycles and historically inadequate maintenance regimes, the degradation rate of expansion joints varies considerably between structures and is inherently difficult to forecast.
Rapidly repairing and replacing loose or defective elements

When expansion joint components are cracked, displaced, or their anchoring fasteners are missing or compromised, immediate repair or replacement is essential to halt progressive deterioration of both the joint assembly and the underlying substructure.

Repairing carriageway surfacing around the joint

Deterioration of the pavement interface adjacent to the joint leads to water ingress and accelerated structural decay. Bridgent restores the carriageway surfacing to its original profile, ensuring a smooth, watertight transition and preventing further damage to the joint housing.

Replacing the entire expansion joint

Where cumulative wear or structural damage renders partial repair uneconomical, Bridgent undertakes full expansion joint replacement. Our in-house design and manufacturing capability ensures precise dimensional compatibility and long-term performance.

Upgrading joints with integrated water collection systems

Upgrading joints with integrated water collection systems

Bridgent can retrofit existing expansion joints with purpose-designed drainage and water collection systems, significantly reducing the risk of chloride-laden water reaching bridge bearings and substructure elements below.

Preventive maintenance programmes

Bridgent develops tailored preventive maintenance schedules for asset managers, combining regular condition monitoring with pre-planned intervention windows to maximise joint service life and avoid costly emergency call-outs.

Assessment
Bridgent is routinely engaged to conduct preliminary structural inspections and detailed condition assessments across all bridge components. Where standard visual surveys are insufficient to characterise the extent of deterioration, our engineers deploy a comprehensive suite of advanced non-destructive testing methods for thorough diagnostic investigation.

Planning and preparation
With dedicated specialist teams focused on structural fitting maintenance, Bridgent is equipped to mobilise rapidly for urgent single-element securing operations or to execute large-scale joint replacement programmes on a scheduled basis. Speed, precision and complete in-house delivery are the hallmarks of our project approach.

Execution
Bridgent fields specialist installation teams supported by activity-specific plant and equipment, together with a maintained inventory of components drawn from multiple joint system families. This enables us to deliver fully integrated, turnkey solutions — coordinating all ancillary trades and services required to achieve a flawless project outcome.

Why choose Bridgent for your project
01.
Swift compliance work to reinstate user safety
Rapid deployment is made possible by our dedicated, highly trained field teams and a rigorously managed inventory of spare components and repair materials, enabling prompt restoration of safe carriageway conditions.
02.
Maximising expansion joint service life
Systematic inspection regimes and proactive condition monitoring allow Bridgent to address emerging defects before they escalate, significantly extending the operational lifespan of each joint assembly.
03.
Reduced environmental footprint
By targeting only the degraded components for replacement rather than wholesale joint removal, Bridgent minimises material waste and the associated carbon impact of each maintenance intervention.
04.
Minimal disruption to traffic operations
Bridgent works closely with asset managers to schedule maintenance windows at the most operationally convenient times, reducing lane closures and limiting the impact on road users throughout the works.
05.
Accelerated response to emerging hazards
Our streamlined mobilisation procedures and close client collaboration enable Bridgent to deploy bespoke repair solutions quickly and efficiently, minimising the period of exposure to structural risk.
06.
Long-term durability of every repair
Bridgent designs and manufactures the expansion joint elements it installs, giving us full control over material specification, dimensional accuracy and quality assurance from procurement through to final handover.
