Unstable Soil Could Be Affecting the Accuracy of Your Truck Weigh Station

This May, spring rains caused significant amount of subsurface erosion at a Calgary truck weigh station. This erosion weakened the soil that supported the weigh station. With heavy trucks sitting on the weigh scale day after day, the concrete piles under the scale began to shift and sink in the unstable ground.

Calgary-based contractors Concrete Specialists were called into action with Martech (now infrStruct) and Prime Resins to fix the unstable weigh scale and stop it from sinking into the ground.

Soil stabilization diagram: 1) Surface water infiltrating the soil and eroding away supporting material from below weigh station’s concrete piles. 2) Prime Resins “Prime Flex 920” grout injected 24” below the base of the pile. 3) Grout expands and fills underground voids then hardens with the soil to form a new base for the concrete pile. The foam-fortified soil reestablishes the necessary frictional forces around the pile for long-term stabilization.
