Case Study: A Temporary Roadway Over Soft Ground
2026-01-30 · SIGMA Technical Team
How a contractor built a temporary roadway over soft ground with linked HDPE panels and kept deliveries moving through the rain.
The challenge
A waterlogged access route was rutting badly and stranding delivery vehicles, threatening the programme. The contractor needed a temporary roadway over soft ground fast, and reusable temp road mats rather than stone — importing stone was slow and costly, and the ground had to be reinstated at handover, so a buried stone road meant a second bill to dig it out.
Why not stone
Stone meant excavation, haulage, compaction, and curing time the schedule did not have, plus removal and disposal at the end. On leased ground with a reinstatement clause, a permanent-feeling solution for a temporary problem was the wrong economics from the start.
The solution
The crew laid a run of linked HDPE panels over the worst sections to form a continuous, shift-resistant roadway. A temporary roadway panel covers ground fast with few joints; on the tighter sections an interlocking access mat locked the run together. It went down by hand and forklift in a single shift, with no excavation.
The result
Vehicles crossed reliably through further rain, the rutting stopped — the whole point of preventing rutting and site damage — and the sub-grade underneath stayed intact, cutting the reinstatement work at handover. The road that solved the access problem also removed the remediation bill that the old rutted route had been building up.
Reused afterward
When the route was no longer needed, the panels were lifted, cleaned, and moved to the next phase — a quick run through cleaning and maintaining HDPE ground mats. Spreading the cost of a reusable surface across several uses is what made the matted road cheaper than stone over the life of the project, not just on day one.
