Pipeline Landslide Repair


Pipeline Landslide Repair

A midstream transmission group asked GeoStabilization International® to design and construct a repair for a series of shallow landslides that had developed on a pipeline section traversing a steep, remote mountainside. Traditional repair techniques were not feasible due to the site’s difficult access and the surrounding environmentally sensitive wetlands, flood plain, and river. GeoStabilization’s engineering group designed a repair using SuperNails® installed with purpose-built limited access “wagon” drills. Due to the severity of the slope grade, GeoStabilization’s experienced crews worked from ropes and climbing harnesses to complete the work safely. The crews installed SuperNails® paired with high-tensile steel mesh along the approximately 14,000 square foot failure area to stabilize the existing material without significant site disturbance or any impact to the pipeline operations. Despite adverse weather conditions throughout the repair, the services were performed on budget and at a fraction of the cost of other more traditional repair methods.
