Roadway & Pavement Lifting & Repair
Shenandoah is a geotechnical construction company that has over 40 years’ experience in roadway and pavement lifting and repair. Our team of highly trained technicians uses a process of deep injection industrial polymers to lift, level, repair and stabilize roadways, highways, bridge approaches, and departure slabs. Restoring these roads, highways and bridges to smooth and safe conditions would save commuters and citizens billions in time and money. This is not only the most cost effective, safe process for roadway and pavement lifting and repair, but also saves billions compared to traditional reconstruction methods. With safety as the highest priority, we have completed thousands of highly successful roadway and pavement lifting and repair projects. Shenandoah’s process is the industry’s fastest, most cost effective, safest, and longest-lasting solution for roadway and pavement lifting and repair.
Lift, Level, and Stabilize your roadways quickly, cost-effectively, and without excavation using our polyurethane injection application.
Common Reasons for Roadway and Pavement Repair
Both natural and man-made factors can lead to weak soils beneath roadway pavement, highways, and concrete slabs. Water flow from heavy rains, floods, storms, expansion and leaks from pipes, storm drains, drainage boxes, etc. compromise the soil 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), causing roadways and pavement to crack, settle, pothole, and sink.
Method for Roadway and Pavement Lifting, and Soil Stabilization Repair
Shenandoah is a licensed affiliate of Uretek. Uretek’s (UDI) 2 stage deep injection polymer process has led the industry since the 1980’s. Commonly known as chemical grouting, UDI’s two stage deep injection polymer process, is a form of compaction & permeation grouting and soil stabilization for structures and water/fluid control. We start each new project with DCP testing used to measure the comparative strength of base soils beneath roadway pavement, highways, and bridge approach slabs. Surface profiles identifying settlement and the testing results are used to identify exact locations and depth levels for the industrial polymer grouting material application. The industrial polymers are precisely injected into 5/8” diameter holes, drilled through the pavement into weak-eroded and voided soil areas. After injection, the polymer expands, densifying and compacting the soils, lifting the soils and pavement back to level grade, while forming a higher weight capacity base that is better than new. The industrial polymers displace any trapped subsurface water and seal the joints and cracks. As the water is repelled, it replaces wet soils with a stable long lasting geo-material subbase. The polymer injection process is repeated using a gridwork of hole locations until all voids are sufficiently treated, and the pavement is lifted back to level grade. As the roadway pavement or slab is lifted, it is precisely monitored using laser measuring devices. The industrial polymers reach 90% of their strength in 15 minutes and 100% of strength in 24 hours. This process keeps lanes of traffic flowing versus reconstruction which could take weeks.
