Roadway Repair Using GCS® Wall Supported by Micropiles

A state Department of Transportation (DOT) contracted GeoStabilization International® to stop an active landslide on a roadway, repair the damage, and stabilize the slope to prevent future road lane collapse.

Geosynthetically Confined Soil® Wall for Landslide Mitigation

After a no-cost, no-obligation visit to the site, GeoStabilization’s engineers offered to design and construct a Geosynthetically Confined Soil® (GSC®) wall to contain the landslide and prevent future ground movement. The fixed-cost proposal envisioned a 28-foot-tall GSC® wall supported on the company’s proprietary micropiles, plus final paving and guardrail enhancements.

As with any landslide mitigation emergency, GeoStabilization’s crews were on site installing the wall within 48 hours of the initial call. GeoStabilization completed the project in record time, allowing the DOT to reopen the road to traffic in just 30 days.

Upon construction, GeoStabilization International® issued a warranty covering not just the materials and installation but also the stability of the GSC® wall. No other company on the market can match this warranty guarantee.

Launched SuperMicropiles™ Underpinning for Superior Bearing Performance

Micropiles are high-strength soil nails used as load-bearing tendons to underpin structure foundations and other support systems. Micropiles are usually less than 12 inches in diameter and feature steel casing and/or a center bar for reinforcement. To install a micropile, GeoStabilization’s crews drill a borehole, insert the soil nail, and then add grouting to compact the ground.

Standard micropiles have many applications but are not suitable for remote areas and rugged terrains. Conventional equipment usually cannot reach limited-access sites. The lack of water and concrete batch plants and the unpredictable ground conditions further complicate the situation.

Unlike traditional micropiles, GeoStabilization’s proprietary Launched SuperMicropiles™ are specifically designed to contain slope movement and support a variety of retaining walls and structures in limited-access environments.

SuperMicropiles™ are suitable for all soil types and ground conditions. They cause minimal noise, vibration, and environmental disturbance. The installation of a SuperMicropiles™ soil nail wall is also faster and more economical than that of traditional GCS® walls.

GeoStabilization International®: A Leader in Slope Stabilization and Landslide Repair

GeoStabilization International® uses the most advanced landslide mitigation technology and methods available. The company combines cutting-edge software and innovative equipment, including a large fleet of limited-access vehicles and proprietary micropiles, to evaluate slope stability and implement the most appropriate remediation solutions.

Thanks to its industry-leading equipment and unrivaled experience, GeoStabilization can often contain landslides without fluids, drill cuttings, or excavations. Most roadway projects require the closure of just one traffic lane during slope stabilization works, resulting in less environmental disturbance, lower carbon footprint, and greater time and cost-savings compared to standard landslide mitigation methods.

Why Choose GeoStabilization International®?

GeoStabilization International® maintains 24/7 emergency response capability across the U.S. and Canada. The company’s representatives can be on-site within 24 to 48 hours of the initial call to evaluate the damage and offer a free, no-obligation, fixed-cost proposal.

No other company can match GeoStabilization’s track record of over 5,500 fixed landslides and rapid response time that makes it possible to reopen critical infrastructure in days, not months.
