Marshalls Redi-Rock on Kier Highways M20/M23 Motorways

A bespoke retaining wall solution has helped Kier Highways to £16 million savings, or 5.6% of the total project budget, on its recent upgrade of stretches of two major UK motorways. Kier Highways’ managed motorway upgrades for the M20 (junctions 3 to 5) and the M23 (junctions 8 to 10) involved converting most of the hard shoulders into traffic lanes to create extra capacity and installing additional gantries with electronic information signs, signals and CCTV cameras to give information about road conditions and speed limits. The use of Marshalls Redi‐Rock walling system, which is UKCA marked for safety and performance, is an example of collaborative working as Kier had requested a custom solution to expedite installation through offsite construction. This included modifying the top block for walls over 1.5m to include a socket for guardrails that would allow safe access for inspections and maintenance. The guardrails were installed under factory‐controlled quality systems, providing additional time savings on site construction and enhancing the quality of the end result, which gave the texture of natural stone for enhanced aesthetics. The use of Redi‐Rock also helped Kier with its green credentials, for as well as eliminating the waste of onsite formwork and reducing excavation that disrupts habitat, the system was fabricated with 25% PFA materials and has a design life of 120 years.
