Bridge Approach Slab Lifting & Leveling

Shenandoah is a geotechnical construction company that has decades of experience in bridge approach and departure slab lifting & leveling. Our team of highly trained professionals uses a process of deep injection industrial polymers to lift, level and stabilize bridge and roadway approaches and departure slabs returning them to a safe, level, and stable condition. Industrial polymers are extremely durable and will withstand heavy loads and vibrations nearly immediately. Unlike other repair methods, our process can be completed rapidly with very limited down time, keeping the traffic flowing. This is the most cost effective, safe process for bridge approach and departure slab lifting & leveling. With safety as the highest priority, Shenandoah has completed thousands of successful bridge & roadway transition lifting & leveling projects.

Our polyurethane injection application is a time-tested solution for stabilizing and realigning bridge approach and departure slabs.

Bridge Approach Slab Lifting & Leveling

Uneven Bridge Approach Slabs Can Lead to Accidents and Endanger Drivers & Passengers

Slab settlement at a bridge approach or departure will start out as a pronounced bump at the entrance or exit of the bridge. As the settlement continues to deteriorate, it can cause serious safety issues for drivers that are unprepared for the jolt and temporary loss of control. Without proper restoration and maintenance, additional damage to the bridge structure and bridge deck will occur.

Who would Utilize a Bridge Approach/Departure Slab Lifting & Leveling Contractor?


Government, state, county & city agencies, and managers & engineers


Transportation engineers, civil engineers, structural engineers, geotechnical engineers, and hydro engineers


Property managers, company operations mangers, industrial operations managers, manufacturing & warehouse managers, etc

Causes for sinking Bridge Approach/Departure Roadway Slabs

Both man-made and natural causes can lead to weak soils beneath roadways, bridges, and concrete transition slabs. Base soils can be weakened by extreme loads and vibration and constant movement. Failure or compromised (MSE) earth walls. The original soil material/composition may not have been packed properly before construction, or nearby drilling, trenching or excavation may result in compromised soil quality. Heavy rains, flooding, water intrusion and displacement of water can lead to erosion and soil failure. Regardless of the cause, weak soils and subsoils result in voids depressions, sinkholes (subsidence) and erosion. Any of these reasons can cause bridge and roadway beds to settle and cause accidents.

Soil Subsidence is a Frequent Problem in Florida

The stability of any structure like bridges, roadways or concrete slabs is based mostly on the soil properties it is built upon. Florida’s sandy, limestone soils and geological conditions can cause voids in soil underneath foundations, concrete slabs, roadways, structures, railroads, and more. Under overbearing weight, the supporting soils will become inadequate to support the structures built upon them. When settlement occurs, it can destroy the value of the assets and property and even render it unsafe. Learn More Here >

What are the Benefits of the Shenandoah Bridge Approach/Departure Slab Lifting, Leveling & Soil Stabilization Process?


Weight Bearing Capacity Restored or Increased


Material Reaches 90% of Strength in 15 Minutes, Assets can be Used Immediately


Precision Pavement Leveling Often up to 1/8” Tolerance with Rapid Polymer Expansion


Use of Small 5/8” Injection Holes, No Deconstruction Reconstruction


Low Pressure Injection of Polymer down to Base and Subbase Soils


One-Time Cost-Effective Method for Long Lasting Restoration.


100% Safe and Eco Friendly

The benefits of the Shenandoah process far outweigh the traditional mudjacking process. Although mudjacking is still used today for traditional foundation & slab lifting/leveling, the materials that are used with mudjacking often require a lengthy installation process and do not stabilize the underlying soil & subsoils as well as our polymer injection process. As a result, mudjacking restorations often have a much shorter life expectancy, which produce much higher costs down the road to resolve recurring problems. Other disadvantages to Mudjacking include the weight of the slurry grout, which can break up with vibration. Slurry grout pumped over distressed bases makes for a short life expectancy. Larger diameter drilling holes are needed, which can further compromise the current structure and mudjacking slurry grout can take up to 7 days to cure.
