Out of Service Doesn't Mean Out of Mind
Culverts move stormwater beneath roads, but they’re only as strong as the soil supporting them.
When pipes are decommissioned, they remain underground as hollow voids waiting to collapse. Over time, pipe walls deteriorate, structures cave in, and voids form beneath roads, buildings, and foundations. Left unfilled, abandoned pipes create sinkholes, trigger settlement, and allow residual contents to leach into soil and groundwater. Our approach fills pipes completely, stabilizes surrounding soil, and eliminates risks without excavation or surface disruption.
From Removal to Permanent Filling
Before: Excavating Pipes That Can’t Be Reached
Traditional pipe removal means digging trenches to expose abandoned infrastructure, cutting out sections, backfilling, and repaving — often impossible beneath buildings, active roads, or utilities. Extended timelines, high costs, and disruption make removal unfeasible for most abandoned systems.
After: Fill Voids, Stabilize Soil, Close Liability
Shenandoah uses pressure grouting to fill abandoned pipes from access points. Specialized grout flows through pipes, fills voids, and penetrates surrounding soil. Material hardens to restore ground integrity, prevent collapse, and encapsulate residual contents. The result? Permanent abandonment without excavation, verified through post-grouting inspection.
From Loose Ends to Case Closed
Pressure grouting permanently fills abandoned pipes, eliminating voids that cause settlement and structural damage.
Collapsed pipes create underground voids that trigger sinkholes, pavement failure, and structural settlement. Pressure grouting fills voids completely, restoring soil integrity and preventing ground failures that close roads, undermine foundations, and trigger emergency responses.
Buildings, roads, and infrastructure over abandoned pipes are at risk when those pipes collapse. Settlement cracks foundations and shifts structures. Pressure grouting eliminates collapse risk by filling voids and stabilizing soil, protecting structures before damage occurs.
Pressure grouting accesses abandoned pipes through manholes, cleanouts, or small boreholes—no trenching, no excavation, no surface disruption. This allows abandonment beneath roads and active infrastructure without undermining adjacent systems.
