Residential buildings, industrial facilities, water towers, dams, ports, bridges… Bridgent has the engineering expertise to protect, repair, strengthen and maintain the structures that underpin modern infrastructure and daily life.
Bridgent's comprehensive bridge and structural concrete repair methods are delivered under our Bridgent Repair quality framework. From initial diagnostic assessment through to design and on-site implementation, every service is precisely tailored to the unique demands of your structure.
Like many engineering materials, concrete degrades over time under the influence of multiple factors. Accurately identifying and understanding the root cause of structural deterioration is fundamental to selecting the correct remediation approach — enabling more durable bridge and infrastructure repairs that meaningfully extend the service life of the structure.
Bridgent invests continuously in R&D to engineer bespoke repair solutions for each project. We hold particular expertise in fire-damaged bridge structures, coastal and marine infrastructure, and complex balcony and cantilever repairs.
Collaborating closely with our Technical Centre and Major Projects division, our 60+ regional offices leverage accumulated best practices to deliver consistent, high-calibre bridge concrete repair outcomes on every project worldwide.
Bridgent provides a fully integrated service portfolio — encompassing structural assessment, concrete repair, strengthening, corrosion protection and long-term maintenance — all certified under our rigorous Bridgent Repair quality standard.
Specialist bridge and structural repair teams operate in every country where Bridgent is present. These professionals undergo regular, intensive training to maintain the highest standards of technical competence and site safety.
Drawing on deep expertise in the behaviour and long-term ageing of bridge and civil structures, Bridgent's engineers define the most appropriate investigation protocol for your specific structure and its pathologies — producing a precise, reliable diagnosis that forms the foundation of every repair strategy.
Working from the client's technical requirements and project constraints, Bridgent develops optimised, customised repair strategies using state-of-the-art materials and methods — enhancing structural safety while optimising quality, programme duration and whole-life cost.
Engineered access solutions are a core Bridgent differentiator. Our in-house engineers understand the complexity of bridge and infrastructure remediation projects, and design safe, productive access systems — including suspended platforms, climbing scaffolds and specialist cradles — that keep challenging projects on programme.
Bridgent acts as principal contractor for bridge and structural repair, deploying specialist teams with advanced techniques applied daily across our global project portfolio. Our construction heritage enables us to execute highly technical works that few providers can match.
Leveraging our knowledge of concrete pathologies and structural failure mechanisms, Bridgent supports asset owners in developing and implementing effective, risk-based maintenance programmes for bridges, viaducts and critical infrastructure.
STRUCTURAL INTEGRITY MANAGEMENT →When repairing or strengthening bridge concrete, the bond quality between the repair material and the existing substrate is paramount — regardless of the overlay thickness or reinforcement configuration. Bridgent employs a range of pressures, flow rates and nozzle configurations to achieve the following surface conditions:
A precision technique employing high-pressure (HP — up to 1,500 bar) or ultra-high-pressure (UHP — up to 3,000 bar) water jets to selectively remove deteriorated or sound concrete from bridge decks, piers and abutments. Hydrodemolition can target localised defects or treat large surface areas. UHP water activates micro-cracks, disintegrates the cement matrix around aggregates and leaves the reinforcement steel undamaged — making it the industry benchmark for safe, effective concrete removal on bridge structures.
Bridgent is highly experienced in the blasting and coating of steel bridge elements, with qualified inspection personnel embedded in our teams. We own and operate our plant and equipment — including dust collection units, spray systems, vacuum units and inspection/testing apparatus. Our coating expertise covers: solvent-free epoxy, zinc-rich primers, multi-component systems, polyurethane, polyester, vinyl ester, acrylics and liquid rubber sealants.
Bridgent applies a comprehensive suite of concrete restoration techniques to address a wide spectrum of bridge and structural defects — from superficial spalling and surface defects to deep structural cracking and section loss in reinforced and prestressed concrete elements.
Suitable for repairing surface-damaged elements of reinforced or prestressed concrete bridge structures, restoring both mechanical performance and original geometry. Equally effective for addressing construction defects. The high strength and stiffness of specialist repair mortars make them ideal for structural concrete repair, including surfaces subject to bridge traffic loading. The Bridgent Repair solution utilises high-performance fibre-reinforced cement mortars, with a fine-finish mortar option for a smooth, dense surface.
Shotcrete is pneumatically applied at high velocity onto the concrete substrate, where it adheres and is compacted by aggregate impact — forming a monolithic composite with the existing structure. Mix design is selected according to the exposure class and the base concrete strength class. Applicable to all types of concrete bridge structural elements, enabling a wide range of reprofile and overlay works in compliance with current standards, with minimal disruption to bridge operations.
Resin and cementitious grouts are used across a broad range of structural and non-structural void-filling applications in bridge and civil structures — from fine crack injection in reinforced concrete elements to mass stabilisation of sub-grade voids. Bridgent provides a complete injection service using high- and low-pressure equipment alongside the latest vacuum injection technologies, with polyester, epoxy and polyurethane resin systems.
Durable bridge concrete repair requires not only addressing the immediate cause of deterioration, but also implementing robust surface protection to prevent recurrence. Bridgent offers a complete range of proven protection systems for bridge decks, piers, abutments and other concrete infrastructure.
Bridgent addresses both water penetration into bridge and civil structures and water loss from water-retaining infrastructure. We carry out structural sealing on a wide variety of structures — frequently in confined or restricted-access environments. Our teams are qualified to apply high-performance acrylic, methacrylate and polyurethane resin grout systems. Each project is assessed individually to identify and implement the optimum pressure-injection technique.
A water-repellent chemical treatment applied to the concrete surface as a liquid or cream to control moisture penetration. The treatment creates a hydrophobic film within the surface pores of the concrete, substantially reducing capillary uptake of liquid pollutants — including chloride-laden water — and thereby slowing or preventing corrosion of bridge reinforcement. Also effective in mitigating freeze-thaw damage. Particularly suited to bridge concrete surfaces not intended to receive a visible coating.
Effective bridge concrete repair must address both the immediate defect and the prevention of future deterioration. As part of our turnkey repair service, Bridgent offers a comprehensive range of protective coating systems — including anti-carbonation coatings, corrosion inhibitors, water-repellent barriers, decorative finishes and anti-graffiti treatments. We recognise that coating performance is directly dependent on substrate preparation quality, and our teams apply the highest standards of surface preparation on every project.
To enhance the building's structural safety, Bridgent deployed multiple complementary concrete repair techniques under a design-and-build contract — delivering a total project cost 34% below the client's original estimate.
Renovation of a historic tunnel in the USA required a careful balance between improving structural condition and preserving unique heritage features; Bridgent collaborated closely with the owner to identify the optimal repair solution.
Extending the operational service life of heavily deteriorated industrial silos while conserving raw material resources was central to the repair strategy Bridgent designed for Golden Bay Cement — ensuring uninterrupted production continuity.
