66” Culvert Failure 20 Feet Deep | Massive Void Repaired with CCCP Trenchless Technology

A 66-inch corrugated metal culvert, buried 20 feet below a commercial center, suffered a complete invert failure. The invert had buckled upward into a compacted mass of corroded metal, causing major soil migration and creating a massive underground void. The asphalt above was beginning to collapse, but open-cut replacement was not possible. This video shows how Utility Asset Management rebuilt the entire system from the inside using a staged trenchless approach: Phase 1 — Structural Stabilization • Installed 54” tunnel liner plates • 146 rings assembled in confined-space conditions • Grouted a large void requiring nine cement trucks • Restored ground support beneath the pavement Phase 2 — Structural Lining (CCCP) • Applied a centrifugally cast concrete pipe structural liner • Spin casting formed a smooth, reinforced concrete pipe • Expected 75–100 year service life Phase 3 — Soil Reinforcement • Final grout injection until refusal • Re-established soil bearing capacity • Stopped ongoing surface settlement The entire rehabilitation was performed without excavation, without shutting down businesses, and without compromising public safety. If your municipality, engineering firm, or public works department is evaluating aging culverts, settlement, or sinkhole risk, Utility Asset Management can help. 📞 Contact UAM: 478-847-2301 🌐 Website: www.UAMonline.com #UtilityAssetManagement #CulvertRehab #Stormwater #Infrastructure #CCCP #TrenchlessTechnology #CivilEngineering #PublicWorks #StormwaterManagement #CulvertFailure #SinkholePrevention #EngineeringCaseStudy #TunnelLinerPlates #DOT
