Mainmark at Tottenham Hale: resin-based platform upgrade lessons for engineers
Reviewed by Tom Sullivan

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.
