Hand-Installed Ground Protection Mats for a National Grid Substation in Waltham Abbey, Enfield
At a National Grid site in Waltham Abbey, Enfield, a substation maintenance company needed safe access for MEWPs and telehandlers across a loose gravel surface. The key constraint was unusually low overhead transmission lines, which ruled out cranes and heavy lifting equipment for mat installation due to health and safety risk. The requirement was a ground protection system that could be installed entirely by hand while still supporting heavy vehicles during a six-week hire period.
The Challenge: Low Overhead Clearance, Loose Gravel, and Heavy Plant Movements
The access route had to be stabilised for repeated movements from MEWPs and telehandlers, but the low overhead clearance prevented the use of conventional lifting methods. This made installation planning as important as product selection.
The site also needed to reduce the risk of vehicles shifting, sinking, or losing traction on loose gravel, while ensuring operations could proceed safely and efficiently within a restricted environment.
Our Solution: MaxiTrack Mats Installed Manually With No Lifting Equipment
GroundGuards recommended MaxiTrack heavy-duty trackway mats as the most suitable system for the constraints on site. Each mat weighs 40kg, allowing two operatives to carry and install them by hand. Despite being man-portable, MaxiTrack is designed to handle loads up to 130 tonnes, supported by its overlapping flange joints and durable plastic structure.
Hand-Laid Temporary Roadway for MEWPs and Telehandlers
Over several hours, the team laid MaxiTrack mats to create a stable temporary roadway across the work area. This provided a firm running surface for plant movements while protecting the underlying ground and improving day-to-day stability.
Safer Installation Under Overhead Lines
Because no cranes or mechanical lifting equipment were required, the installation approach reduced risk in the vicinity of low overhead transmission lines and allowed the work to be completed quickly within the site’s restrictions.
Results: Stable Access Delivered for the Full Six-Week Hire
The project ran smoothly throughout the six-week hire period. MaxiTrack provided the reliable surface needed for access and operations, helping keep equipment stable while protecting the ground below.
The client was pleased with the performance and is now considering MaxiTrack again for a future project site in Coventry.
Key Lessons for Ground Protection Under Low Overhead Restrictions
- Where overhead clearance is limited, specify man-portable mats to avoid craneage and reduce risk near live services.
- Stabilise loose gravel surfaces early to improve plant control and reduce the likelihood of slippage or uneven settlement.
- Use systems with secure joints that stay locked under turning and braking, particularly with MEWPs and telehandlers.
- Installation method is as critical as mat selection on restricted utility sites—plan handling and sequencing up front.
- A successful hire installation can provide a straightforward template for repeat use on future substations and utility sites.
