GeoStabilization International uses ScourMicropiles™ to protect bridge foundations, culverts, open-bottom structures, and stream-adjacent infrastructure from scour and streambed erosion across Canada. Scour is one of the leading causes of foundation instability in waterways, especially in regions affected by spring runoff, high-flow events, freeze–thaw cycles, and changing hydrologic conditions.
ScourMicropiles™ offer an engineered, low-disturbance solution that reinforces vulnerable streambeds while supporting long-term infrastructure reliability and public safety.
ScourMicropiles™ are a specialized application of micropile technology designed specifically for scour mitigation. Traditional micropiles are small-diameter structural elements installed to transfer loads to deeper competent soils or bedrock. ScourMicropiles™ adapt that concept to stabilize eroded or erosion-prone streambeds around structural foundations and hydraulic crossings.
Scour occurs when flowing water removes sediment around abutments, piers, or other stream-adjacent structures. Over time, this can create voids and loss of support that leads to settlement, tilting, or structural distress. ScourMicropiles™ help reduce these risks by reinforcing the streambed with a structural framework that limits particle displacement during high-energy flow conditions.
Many Canadian waterways involve restricted access, regulated riparian zones, and the need to minimize environmental disturbance. ScourMicropiles™ can be installed using methods that reduce excavation and equipment footprint, which is especially valuable near streams, wetlands, and erosion-sensitive corridors.
In select applications, ScourMicropiles™ may be installed using GSI’s Soil Nail Launcher™, which allows rapid placement of steel elements with minimal disruption compared to conventional drilling operations. This approach can be useful for remote sites, confined crossings, and projects where limiting site disturbance and maintaining safer work zones are key priorities.
After ScourMicropiles™ are installed, properly graded alluvium or rock can be placed to rebuild scour holes, restore streambed profile, and support stable hydraulic function. Depending on sediment type and flow conditions:
ScourMicropiles™ can also be integrated with other stabilization systems, including Geosynthetically Confined Soil® (GCS®) Walls, when projects require combined slope and water-adjacent protection.
If your bridge, culvert, or stream crossing is showing signs of scour, erosion, or loss of support, GeoStabilization International can help. Our engineers and field teams deliver engineered ScourMicropiles™ solutions designed to protect foundations, restore stability, and improve long-term performance in Canadian waterways.
