    We’re in the business of support. How can we help?

    At GIE, relationships are the foundation of all we do. That’s why, as former geotechnical consulting engineers ourselves, you’ll find we’re always the first to the geotech’s side. And why you’ll work with the same engineer throughout the entirety of your project. That’s why we station people who are well-versed in your local geology in your local market. And why every last design is either done, or reviewed, by one of our owners. Because, at the end of the day, ground improvement really does come down to one simple thing. Giving you total confidence in your footing.

    Please contact the geotechnical/structural engineer conveniently located near you.
