History & Philosophy

History

GeoStablization International began through the vision of founders Robert Barrett, P.G. and Al Ruckman, P.E..  Both had spent 30+ year careers in public sector transportation and became known internationally for their contributions and leadership in geotechnical research, design, construction, and maintenance.  Building on their broad experience and inspired by their research discovery, the Soil Nail Launcher, they formed Soil Nail Launcher, Inc. a landslide remediation company.  In 2008, sons Colby Barrett, P.E. and Tim Ruckman took over the company and have continued the philosophy of their fathers. Barrett and Ruckman continued to build from that foundation into today’s GeoStabilization International, the leading geohazard mitigation company in North America.

Philosophy

GeoStabilization International credits its success to the founding philosophy of serving the client with the newest technologies, the best solutions, and the fastest possible service.  Through many years of training, experience, and this founding philosophy, GSI engineers and constructors now stand as the most qualified and most experienced in the industry.

Environmental Benefits

GSI’s focus on bringing new technologies to the geohazard repair industry reduces project time, cost, and also minimizes environmental impact.  Our geotechnical engineering staff focuses on the most efficient use of component materials (for example, using steel and fiberglass in tensile applications rather than in bending or shear) while our field operations group focuses on creating purpose-built equipment to maximize installation speed while minimizing site disturbance. For example, our Soil Nail Launchers™ can install up to 250 20-foot long nails in a day, using an excavator mounted carrier that eliminates the need for access roads. Our fleet of purpose-built wagon drills, spider-excavator mounted drills, and  vertical access air-track drills can be utilized on slopes of any inclination to drill holes up to 6-inches in diameter up to 200-feet deep – again, with no need for access roads or significant site disturbance, making GSI’s approach ideal not only for difficult access sites, but also for environmentally sensitive areas and coastal/riparian sites.

ALBERT RUCKMAN, P.E. : Founder
ALBERT RUCKMAN, P.E., Founder

Al holds a B.S. in Civil Engineering from the University of Colorado and holds four patents in the area of rock and soil slope stabilization methods and innovations in soil nailing. Al worked at the Colorado Department of Highways from 1963 to 1982 in the area of materials engineering and geotechnical engineering. During this time he was involved in highway designs including slope stability, highway stability, structural inspections and material designs. Research performed during this time included soil collapse potential, swelling of bedded shales and clays, and soil reinforcement. Included in this work was the design and construction supervision of the Glenwood Canyon fabric walls with instrumentation for determining strain and deformation of the full height test walls.

In 1982 he began work for Corn Construction Company as the Materials and Quality Control Engineer. In this position he was responsible for locating and obtaining materials for highway construction projects in five western states. In 1986 he took over the materials laboratory of Sergent, Hauskins & Beckwith Consulting Engineers in Phoenix. In this position he was responsible for the instrumentation of structural foundation elements, including the installation and operation of load cells, inclinometers, strain gauges, piezometers, and supervision, training and operation of the 1000 ton load test frame. Among his projects was the design of fabric reinforced soil walls.

In 1994 Al returned to Denver to consult independently for soil nail shoring and reinforced soil design and construction in Colorado. He designed and supervised construction of geosynthetic confined soil walls as great as 93 feet in height. He designed and supervised construction of ground anchored and soil nail walls up to 110 feet in height. After consulting for Yenter Companies for several years, he joined Yenter as Chief Engineer and later became President of the company.

Al has design responsibility for hundreds of reinforced soil structures throughout the U. S. and internationally, valued at well over a 300 million dollars, and over 100 soil nail walls and landslide stabilization repairs using soil nails totaling over 100,000 square feet. He is one of the top geotechnical and structural researchers, innovators, designers and constructors in the world, and currently lives in Palisade, Colorado.

PETER BULLOCK, P.Eng., M.Eng. : Principal Engineer
PETER BULLOCK, P.Eng., M.Eng., Principal Engineer

Peter is a native of British Columbia, holds a Geological Engineering degree from the University of British Columbia with over 20 years of experience within the earth science and engineering fields.  His early days were spent primarily in the forest and mining sectors both within the corporate and consulting sectors.  Starting in 2006, Peter rounded out this experience with a 7 year stint as a Regional Geotechnical Engineer for the Ministry of Transportation in BC.

Through the years Peter has been involved with hundreds of projects that ranged from routine maintenance to multi million-dollar legacy and capital works projects.  Many of these projects were scattered across the globe and ranged from African deserts to the ice of Antarctica.  His earlier years focused on the natural hazard side of geotechnical engineering.  These hazards included landslides, slope stability and rock fall challenges.  As his career progressed, he became more interested in the structural side of engineering. This led him to complete his Masters of Engineering at the University of Saskatchewan, gained him the BC Premiers Award for Innovation and ultimately this role with GSI.  Peter now resides on Vancouver Island with his wife and 3 young boys.
