Stabilizing a Highway Soft Spot Above a Culvert
The Challenge
A recurring low spot had developed on a highway near Lumsden. The issue was linked to soil failure around a culvert beneath the road, creating a soft spot and an ongoing risk of further settlement.
A conventional repair could have required significant excavation and a full road closure.
The Solution
ECO used Deep FoamJection to inject polyurethane foam between the highway and the existing culvert. The process stabilized the surrounding soil while simultaneously lifting and levelling the affected lane.
The Result
The highway was stabilized and the lane was restored with only a partial road closure, allowing traffic to continue using the other lane throughout the project.
