AI-Powered Case Study: Stabilizing Charlotte, NC’s Concrete to Prevent Sinkholes
In Charlotte, NC, erosion caused by water intrusion was compromising underground stormwater systems, creating dangerous sinkholes and threatening nearby infrastructure.
To address the issue, DryPro, a Groundworks company, applied 125 units of PolyRenewal™ across three sites.
Their certified team worked safely in confined spaces to seal water entry points and stabilize soil.
The Challenge
- Persistent water intrusion washed soil into Charlotte’s stormwater system.
- This led to severe erosion, sinkholes, and compromised underground structures.
- Public safety, roads, sidewalks, and utilities were at risk without immediate action.
The Solution
- Applied 125 units of PolyRenewal™ across three key underground sites.
- Sealed active water entry points and stabilized soil around stormwater infrastructure.
- Crew followed confined space safety protocols to complete the work efficiently and safely.
The Impact
- The stormwater system is now sealed and reinforced, reducing future erosion.
- Sinkhole risk has been eliminated in the affected areas.
- City officials were pleased with the results and gained peace of mind knowing the system is secure.
Before Concrete Lifting:
Erosion in the Stormwater System
As shown in the underground structures, persistent water intrusion washed away the surrounding soil.
This erosion weakened the structural integrity of the stormwater system and left large voids in the soil—creating dangerous conditions that could lead to sinkholes.
Public Safety at Risk
As the soil continued to erode, the ground above became unstable. This instability put roads, sidewalks, and utilities in jeopardy, increasing the risk of sudden collapse. Without repairs, the situation posed serious threats to both city infrastructure and resident safety.
After Concrete Lifting:
Targeted PolyRenewal™ Injection
To stop active water intrusion and strengthen the surrounding soil, the team installed 125 units of Single Component PolyRenewal™ at three key underground locations.
This expansive polyurethane filled voids and sealed leaks, creating a watertight barrier that stabilized the compromised areas and stopped future erosion.
Specialized Confined Space Protocols
Because this project took place in narrow, underground environments, the crew followed confined space entry procedures for safety. Their advanced training ensured the repairs were completed efficiently and safely—even in low-oxygen, restricted-access areas—while minimizing disruption to the surrounding infrastructure.
Seeing the Positive Effects
The City of Charlotte can now rely on a stabilized stormwater system that is free from the threats of sinkholes and water intrusion.
The project’s success highlights the effectiveness of the materials and techniques used, demonstrating the team’s expertise in handling complex infrastructure challenges.
The PolyRenewal™not only sealed the problem areas but reinforced the soil, reducing the likelihood of future erosion.
City officials expressed satisfaction with the results, knowing these critical areas are now secure and protected from future issues.

I cannot say enough good things about this company and their staff. Our point-of-contact was Steve. He was an absolute top-notch professional. He exhibited top quality customer service and communication. He could explain the more technical parts in a way a layperson could easily understand. He was courteous, easy-going, and very conscientious inside and with home. If you think you might have structure issues, I highly recommend consulting with Grooundworks, and ask for Steve!
