Working within a tightly controlled Bank Holiday rail possession, our team delivered specialist ground improvement beneath 77 new platform foundation locations using our Teretek® engineered resin injection solution. The project was critical to supporting the installation of new GRP platform structures while meeting stringent bearing capacity requirements.

Key project highlights:

• Ground improvement across 77 foundation pads

• Minimum bearing capacity target of 75kPa achieved

• Delivery within restricted rail possession windows

• No excavation required, minimising disruption and coordination risk

• Real-time monitoring and comprehensive QA/QC data capture

• Post-treatment validation confirming improved ground strength

The Teretek® solution enabled precise, controlled treatment within a constrained rail environment, providing a fast and efficient alternative to traditional excavation and replacement methods. The approach also delivered significant sustainability benefits, including reduced plant usage, zero spoil generation, lower embodied carbon, and enhanced long-term asset performance.

As Raj Sharma, Contracts Manager at CML, commented:
"Mainmark provided a highly professional and technically capable service throughout the works at Tottenham Hale Station. Their design input, engineering expertise, and proactive weekend support were key to delivering a practical, cost-effective solution without compromising quality or programme."

Projects like this demonstrate how innovative ground engineering solutions can help the rail sector deliver critical upgrades safely, efficiently and sustainably.
