GeoStabilization International is the temporary shoring contractor of choice for tight urban excavations, roadway cuts, and time-critical repairs. For more than 20 years, our teams have stabilized slopes, excavations, and adjacent structures across North America, keeping crews safe and projects on schedule and within budget. Using launched soil nails, SuperNail™ systems, and Soil Nail Launcher™ technology, we deliver rapid, low-disruption shoring that can be installed from the surface and accept load seconds after installation.
Compact equipment, rope access, and spider excavators minimize excavation and disruption in active or confined sites.
Our nationwide fleet allows fast deployment for both planned and emergency projects.
Launched soil nails and SuperNail™ systems outperform conventional shoring in speed, reach, and adaptability, making them ideal for restricted corridors and emergency work.
Value-engineered designs and top-down methods are often up to 30 percent more cost-effective than traditional shoring, with fewer interfaces and change orders.
Work-at-height procedures, traffic control expertise, and rigorous testing meet or exceed industry standards.
As a trusted temporary shoring contractor, GSI provides design-build excavation support and earth retention solutions nationwide:
Evaluate excavation geometry, surcharge loads, utilities, groundwater, and access constraints.
Define nail type, lengths, spacing, facing, and drainage to meet performance and durability goals.
Launch or drill nails from the surface; pressure grout as specified. Nails take load immediately, allowing concurrent excavation.
Install horizontal drains and weeps to manage inflow and improve stability.
Apply mesh or shotcrete facings, complete verification testing, and provide documentation for closeout.
During a historic theatre renovation, GSI installed limited-access, soil-nailed shoring to maintain public access and protect adjacent buildings. Top-down installation and launched drains allowed concurrent excavation, reduced traffic disruption, and kept the project on schedule.
Nails carry load immediately, allowing excavation to advance without delay.
Streamlined design-build delivery reduces trades, footprint, and overhead.
Local response supported by a national network of specialized crews.
Proven methods and quality management ensure safe, predictable outcomes.
