Stable Access for Motorway Services Construction on Peat Ground
GroundGuards supported a new motorway services development in Warrington by providing temporary access across a peat bog site during early groundworks. The project required dependable routes for heavy plant, HGVs, and sheet piling operations, despite very poor ground stability. To keep the programme moving safely, GroundGuards supplied XtremeMat to create a stable access road and working platform across the site.
The Challenge
From the outset, the site presented difficult ground conditions. The whole area sat on peat, which meant low bearing capacity and an increased risk of rutting, movement, and localised ground failure under repeated traffic loads.
This created a practical problem for early works. Heavy equipment, materials, and vehicles needed to move consistently across the site, but unreliable ground could easily have restricted access, slowed progress, and affected safety.
The layout added another layer of complexity. Vehicles needed to navigate the site efficiently, particularly around corners, where tighter turns could reduce flow and increase strain on both the ground and the machines using it.
Our Solution
GroundGuards supplied 661 XtremeMats to form a robust temporary access network across the development. The mats were chosen for their high strength core, making them well suited to soft and unstable ground conditions such as peat.
The installation created a 6 metre wide access road, giving large vehicles the space needed to move safely and, where required, allowing for two way traffic. This helped support day to day site activity as construction works increased.
A key part of the layout was the way the mats were installed in turning areas. Instead of creating standard right angle corners, the team overlapped mats in selected sections to form sweeping bends. This improved manoeuvrability for plant and HGVs and helped maintain smoother vehicle movement across the site.
Alongside providing access, the mat system also created a stable working platform for sheet piling operations. This allowed heavy equipment to operate more safely without placing unnecessary stress on the already weak ground below.
Results & Outcome
Once installed, the mat system provided reliable access across terrain that would otherwise have been difficult to work on. Loads were distributed more effectively, which helped prevent ground disturbance and maintain a firm, usable surface throughout the works.
The wider road layout and improved corner design also made a noticeable difference to vehicle movement. Plant and HGVs were able to move around the site more smoothly, supporting safer operations and reducing delays.
With stable access and a dependable working platform in place, sheet piling works continued without interruption, helping the project stay on schedule. The scheme showed how careful planning and the right ground protection system can make challenging ground conditions manageable on live construction sites.
What This Means for Similar Projects
- Peat and other weak ground conditions need an access solution that spreads load effectively from the start.
- Temporary road width matters, especially where heavy vehicles and plant need to pass safely and keep site traffic moving.
- Corner design should not be overlooked, as smoother turning routes can improve vehicle flow and reduce pressure on the ground.
- A well planned mat layout can do more than provide access, it can also support critical operations such as piling and other heavy groundwork activities.
- Choosing a proven temporary access system early can help protect programme, safety, and ground conditions throughout the project.
