AI-Powered The Challenge
Erosion around a 130-foot-long culvert raised concerns about subsidence and surface deflection, especially with future construction planned above it.
The Solution
Utilized polymer injection at 3-foot intervals to stabilize and support the 130-foot culvert, ensuring it was ready for future construction.
The Impact
The project stabilized all 130 feet of the culvert in just 3 days, avoiding settlement and maintaining the stream’s flow to the customer’s satisfaction.

Erosion and shifting of a 130 ft culvert.
The 130-foot-long culvert, located 30 feet below grade, was facing significant erosion due to water intrusion around its perimeter from a nearby stream. This erosion weakened the surrounding soils, creating a concern for potential subsidence or shifting of the culvert, which could lead to deflection of the surface above. With future construction planned on top of the culvert, the risk of deflection became an urgent issue that required immediate attention to stabilize the structure and prevent further damage.

The Solution
Stabilize culvert with polymer injections in 3-foot intervals.
To address the erosion and stabilize the 130-foot culvert, Groundworks utilized a polymer injection process to fill the voids and strengthen the base soils. Injections were strategically placed at 3-foot intervals along the culvert to ensure full stabilization, providing the necessary support to prevent subsidence and surface deflection. This method effectively reinforced the structure, preparing it for future construction above.
The Impact
Polymer injections completed in 3 days.
The polymer injection process was completed efficiently in just three days, ensuring all 130 feet of the culvert were fully stabilized while maintaining the natural stream flow. The customer expressed great satisfaction with the outcome, as the stabilization successfully prevented any potential settlement or deflection of the culvert.
