Rolling Road Installation Case Study

National Gas Services was tasked with removing a 30" high-pressure block valve arrangement located adjacent to a Site of Special Scientific Interest (SSSI). The project required excavating two deep stopple pits, each 4 metres deep and 14 metres long, before installing grouted tees, safety bags, and an 8" steel bypass welded on-site.

However, the ground conditions posed a significant obstacle. The area was boggy and uneven, making it unsuitable for traditional temporary trackway systems—especially with the need to accommodate heavy machinery, including an 80-tonne crane. Complicating matters further, all access solutions needed to be safe for use over a live high-pressure gas main.

UIS responded rapidly with a tailored solution using the Rolling Road system, deploying a combination of Midi and predominantly Maxi boards. The heavy-duty Maxi boards, with their interlocking, modular design, provided a stable, high-performance platform capable of supporting substantial loads without compromising ground integrity.

Over the course of the seven-month project, 109 Rolling Road boards were installed, delivering safe, consistent access for all required plant and machinery. Thanks to its adaptability, strength, and low-impact footprint, Rolling Road not only met but exceeded the client's expectations—so much so that National Gas Services has since adopted UIS Rolling Road as their standard temporary trackway solution for future projects.
