Jackson was highly commended in the ICE South East Awards for its work on the Gade Valley Expansion Joint Replacement Scheme on the M25.
The project involved the replacement of two expansion joints on the Gade Valley Viaduct, at Junction 20, which were skewed by more than 30 degrees.
Using temporary over-ramps which were originally developed for a previous Jackson project on the QEII Bridge, this innovative temporary works solution was successfully re-deployed following minimal modification, allowing the team to complete the project with very little disruption to traffic.
This ramp solution has the potential to be re-used at a further 26 locations across the M25 network, and they are currently being used on a similar project at New Haw Viaduct.
Whilst in-situ, 30.2 million vehicles drove over the ramps at Gade Valley, their drivers were largely unaware of their presence. Considering this number in the context of delays that could have been caused by the works, the benefits for this temporary works method are unquantifiable, and in that respect, this innovation has been a triumph for the industry.

Collaboration is currently our industry’s favourite buzzword, so here it is, in action, delivering rock solid results for the benefit of the UK’s road network.Working with our clients, Connect Plus & Connect Plus Services, Jackson carried out some trials of a new waterproofing agent, Matacryl on the M25 Mardyke Viaduct. The benefit of Matacryl is that it’s easier to apply, quicker to cure, and can be installed under far less stringent weather conditions than conventional waterproofing materials, which means far fewer delays to waterproofing works. Our Framework Director Paul Watson explains: “The initial trial was a great success however, we faced a real challenge in sourcing the material due to a lack of suppliers in the UK. To solve the problem, we worked with the manufacturer, RPM, and one of our supply chain partners Techjoint, who agreed to get involved. As a result, Matacryl is now being used widely across the UK’s road network, reducing delays to waterproofing works, and keeping the traffic flowing.” Mark Healy from Techjoint said: “As a result of the collaborative nature of our relationship with Jackson and Connect Plus, we were confident enough to invest in new plant, equipment, training and development of new products. The Jackson/CP team are always there at the end of the phone if we ever need any advice, even on competitor’s projects and this is something that is unique in our business.” The results from the initial trials have since been shared with other Framework suppliers through the Research and Development Forums, and the Collaboration Portal, and Matacryl is now widely used across the UK’s highways network. Furthermore, this relationship, a shining example of best practice collaboration with the supply chain, has led Jackson to be shortlisted for the NEC Contractor of the Year award, which has a particular emphasis on clause 10.1 – the obligation to act in a spirit of mutual trust. The winner will be announced at the NEC Annual Seminar at the end of this month.
