Waterproofing Solution for a Masonry Barrelled Viaduct
In railway infrastructure, preventing water ingress is critical for maintaining safety and operational efficiency. This project in Cambridgeshire involved Total Specialist Maintenance (TSM) providing an effective waterproofing solution for a rail contractor facing significant challenges with water ingress in a masonry barrelled viaduct.
The Challenge
The client required a waterproofing solution for a masonry barrelled viaduct to stop water ingress without lifting the track. This was essential to minimise disruption to rail services and ensure passenger safety. Key concerns included:
- Maintaining Operational Integrity: Ensuring the integrity of the structure while maintaining ongoing railway operations was paramount, as any disruption could affect service schedules and passenger safety.
- Preventing Water Damage: The existing water ingress posed risks to the viaduct’s structural integrity, necessitating a swift and effective solution to prevent further deterioration.
The Solution
TSM implemented a comprehensive waterproofing strategy that included several critical steps:
- Drilling: The first step involved accessing the back of the extrados of the masonry barrelled arch. This drilling was essential to facilitate the waterproofing process without disrupting the existing rail infrastructure.
- Injecting Waterproof Resin: TSM applied a specialised waterproof injection resin to the back of the structure. This resin was designed to effectively halt water ingress, creating a durable barrier against moisture penetration.
- Installing Drainage Relief Pipes: To manage water flow and prevent future issues, TSM implemented positive drainage relief pipes. These pipes directed any potential water away from the structure, further enhancing the waterproofing system’s effectiveness.
- Testing: After completion of the waterproofing system, thorough testing was conducted to verify its effectiveness. This included monitoring for any residual water ingress and ensuring that the integrity of the waterproofing solution was intact.
Project Management Excellence
TSM’s project management team played a vital role in ensuring the successful execution of the waterproofing project. By coordinating closely with the rail contractor and adhering to strict timelines, TSM minimised disruptions to rail services. Regular updates and communication with all stakeholders kept everyone informed throughout the process, ensuring alignment on project goals.
Safety Considerations
Safety was a top priority throughout the project. TSM implemented rigorous safety protocols to protect both workers and rail services during the waterproofing process. All operatives were trained in safety procedures specific to working in railway environments, ensuring compliance with industry standards.
Environmental Considerations
The waterproofing materials used were environmentally friendly, posing no risk to the surrounding ecosystem. TSM’s commitment to sustainable practices ensured that the project aligned with best practices for environmental safety.
