    Mainmark at Tottenham Hale: resin-based platform upgrade lessons for engineers

    First reported on The Construction Index

    30 Second Briefing

    Ground engineer Mainmark UK has used its Teretek engineered resin injection system to improve ground conditions for 77 new foundation locations at Network Rail’s Tottenham Hale station, enabling replacement of deteriorating precast concrete platforms with glass‑reinforced polymer units. Working with tier one contractor CML over a single bank holiday weekend, the team completed the works in three shifts by injecting resin through small‑diameter access points to depths of around 2m, avoiding excavation. The solution densified variable made ground and granular soils, reducing programme risk and construction disruption for the live rail environment.

    Technical Brief

    • Teretek resin was injected via small-diameter access points, enabling precise treatment beneath each foundation location.
    • Ground improvement targeted approximately 2 m depth beneath every new platform foundation position.
    • Variable made ground and granular soils required in-situ densification rather than replacement or deep foundations.
    • Glass‑reinforced polymer platform units demand reliable, uniform support to control long‑term deflection and serviceability.
    • Avoiding excavation reduced interface risk with buried services and existing platform structural elements.
    • Resin injection provided measurable stiffness gain, supporting CML’s programme and quality requirements for the upgrade.

    Our Take

    Network Rail’s appearance across several recent pieces in our database – from the Reedham swing bridge repair to overhead line renewals between Bethnal Green and Cheshunt/Enfield Town – signals a sustained programme of asset life-extension where targeted geotechnical strengthening at stations like Tottenham Hale fits into a broader resilience push.

    Treating 77 discrete foundation locations at Tottenham Hale Station suggests a preference for localised ground improvement over wholesale reconstruction, a pattern seen in other UK rail works where operators aim to minimise passenger disruption and possession time while still addressing long-term settlement risk.

    Lovell pauses Charlton housing work after nearby partial collapse

    Lovell has paused construction on a nearby housing development in Charlton, south London, after three homes on Woodland Terrace suffered a partial collapse. Lovell took the decision to pause work while it works with the Royal Borough of Greenwich and other relevant parties to understand what happened. The cause of the incident has not been established. Lovell commissioned an independent structural engineer to carry out a visual survey of the properties.

    British Tunnelling Society chair: planning and risk lessons for UK tunnel engineers

    British Tunnelling Society chair and Jacobs tunnels director for Europe Alastair Smith calls for earlier geotechnical investigation and constructability input in UK tunnel planning to cut redesign and delay on major schemes. Drawing on five decades of work on large-bore metro, water and road tunnels worldwide, he points to fragmented client governance and late contractor involvement as key causes of cost escalation. Smith urges standardised design frameworks and clearer risk allocation for ground conditions to speed delivery of long linear assets.

    Network Rail £77.6m Wales & Western civils framework: key notes for geotechnical teams

    Network Rail has launched an Expression of Interest for a £77.6M multi-year framework to deliver geotechnical and civil engineering works across its Wales and Western regions, covering earthworks, structures and associated lineside assets. The framework is expected to package embankment and cutting stabilisation, retaining walls, culverts and bridge repairs into regional workbanks, with contractors providing design-and-build capability under railway possession and access constraints. Bidders will need proven experience in rail-adjacent geotechnics, temporary works and working under live traffic with tight blockade windows.
