Causes of sinking railroad tracks & railroad crossings:

Both man-made and natural causes can lead to weak soils beneath railroad tracks. Base soils can be weakened by extreme loads, vibration, and constant movement. 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 railroad track beds to fail and cause derailment.

Soil Subsidence is a Frequent Problem in Florida

The stability of any structure, such as railroad tracks or concrete slabs, is based primarily 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.

What are the Benefits of the Shenandoah Railroad Track Lifting, Leveling & Soil Stabilization Process?

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.
