At GeoStabilization International® (GSI), we don’t just build solutions—we protect lives, infrastructure, and communities from the dangers of geohazards. As the #1 design-build soil stabilization company in the United States and Canada, we specialize in tackling the toughest challenges, from emergency landslide repairs and retaining wall repairs to advanced cased drilling solutions.

Our team is driven by innovation, expertise, and a passion for problem-solving. With cutting-edge technology, specialized equipment, and strategic global partnerships, we can stabilize slopes, secure foundations, and restore critical infrastructure—no matter the geological conditions.

We are headquartered in Westminster, Colorado, but hire crew members from every state in the union for traveling work, and deliver projects across the country.
