Project Case Study
Project Title: Tilbury, Essex– Bridge Concrete Repairs & Corrosion Control
Location: Tilbury, Essex
Sector: Infrastructure (Highways / Rail Interface)
Project Overview
Concrete Repair Solutions were appointed to undertake targeted concrete repair and corrosion control works to Fort Road Bridge in Tilbury, Essex.
The scope focused on the North Abutment, where areas of deteriorated concrete and reinforcement corrosion required controlled removal, treatment, installation of galvanic protection, and reinstatement using spray-applied repair systems.
The works formed part of a durability-led intervention to reinstate structural integrity and mitigate ongoing corrosion risk within a live bridge environment.
What We Did
- Broke out defective concrete cover using hydro-demolition techniques
- Exposed and grit blasted reinforcement to remove corrosion products
- Installed PatchGuard galvanic anodes at 350mm centres
- Reinstated concrete cover using spray-applied repair mortar
- Delivered works in a controlled and sequenced manner appropriate to an operational bridge structure
Technical Overview
Fort Road Bridge is a two-span reinforced concrete road bridge spanning over the London, Tilbury and Southend railway line.
The structure comprises north and south abutments with a central reinforced concrete pier, cast in-situ. The deck slab is formed of reinforced concrete with a tarmac waterproofing detail applied to the deck surfaces. The deck is supported on five arched beams with cantilevered edges along the full span.
The repair methodology addressed localised deterioration to the North Abutment. Hydro-demolition was used to achieve controlled breakout and preserve sound substrate. Reinforcement was mechanically prepared prior to installation of galvanic anodes to provide ongoing corrosion mitigation at repair perimeters. Concrete cover was reinstated using a spray-applied repair system suitable for structural bridge environments.
Project Challenges
- Working within an infrastructure setting spanning an operational railway line
- Achieving controlled breakout without excessive removal
- Integrating galvanic corrosion control within localised repairs
- Sequencing works safely within access and operational constraints
Outcome
The completed works reinstated the structural integrity of the affected abutment areas and incorporated galvanic corrosion control to reduce the risk of future reinforcement deterioration.
Repairs were delivered using controlled preparation and spray-applied reinstatement, providing a durable and technically appropriate solution for a live bridge asset.
