Underground Utilities Repair & Restoration

We use only the highest-grade materials designed to last decades if not longer

Common causes of Underground Utilities failures:

Both natural and man-made causes can lead to weak soils around, beneath, and above underground utilities & structures. Water flow and leaks from pipes, storm drains, drainage boxes, etc. compromise the soils and cause erosion. The original soil material and composition may not have been packed properly before construction, or nearby drilling, trenching, excavation, or heavy load bearing use and vibrations found on roadways and railroads, may result in compromised soil quality. Regardless of the cause, weak soils and subbase result in soil erosion, soil voids, pockets, and sink holes (subsidence). These problems are generally caused by the inflow & infiltration of groundwater from leaks, heavy rainy seasons, and flooding. All of which leads to the formation of voids in the base and subbase soil around the structure

Trenchless Underground Utilities Repair and Restoration Solution:

Shenandoah’s deep injection eco-friendly water-resistant expansive polymer is strategically injected into the foundation soils beneath, around and above the underground utilities and structures at various elevations and in a grid pattern to densify, compact, and stabilize loose and voided soils. The polymers are injected around joints to help stabilize soils and encase and seal leaking pipes, structures, and joints. The process lifts, aligns, and stabilizes the buried utilities.
