The JG Advantage

DEEP FOUNDATIONS | EARTH RETENTION | GROUND IMPROVEMENT | SLOPE STABILITY

From initial on-site analysis to final design and construction, JG offers design-build solutions for a variety of geotechnical & structural projects.

Led by a team of experts with decades of experience in deep foundations, earth retention, ground improvement, and slope stability, our Geotechnical & Structural Division is deeply committed to your project’s success. We take the time to understand each project’s unique conditions in order to create the most precise, efficient, and cost-effective solution.

From the bid phase through project completion, our Geotechnical & Structural engineers work directly with the owner, providing a consistent and reliable experience. By handling the entire process in-house, JG is able to estimate more accurately, design better solutions, and build with more precision than many of our competitors.

What Our Clients Say

Hear directly from those who’ve experienced the JG difference firsthand.

“Working with JG was a great experience from concept to completion. Deep subsurface caverns and a high water-table required and fully exhibited their expertise with concrete-encased micropiles, installing 40% additional material while still completing their work ahead of schedule. If you have deep foundation work, I highly recommend JG.”  
Alec S.

“My experiences with the entire JG team at the project development, design, and construction phases has been outstanding, time and again.  Their high level of professionalism, expertise, experience, attention to detail, workmanship, and flexibility are exhibited throughout the organization and they will continue to be a go-to resource and reference for me for many years to come.”
Stephen S.

“If you’re in search of a deep foundations contractor who delivers results on time and within budget you’ve come to the right place. Our 29 acre development recently completed its first Class A Office Building with JG  as our foundations partner. While our schedule had us installing Micropiles through the winter months, JG’s field crew led by their Geotechnical & Structural Division Manager, Fred Tarquinio didn’t miss a beat and actually finished their installation ahead of schedule. From the bid phase through award and finishing with the completion of their Scope of Work the entire JG organization was a pleasure to work. A trusted partner and true professionals who do what they say and do it right. Will certainly be working together on future buildings and developments.”
Vincent S.

“We have worked with JG on multiple geotechnical projects and they have provided valuable technical experience, honesty and have delivered high-quality work each time. We look forward to working with them again!”
John R.

“Our company has used JG for several projects over the years.  JG is a very reliable and trustworthy company to work with.  They always complete their work in a safe, efficient, and professional manner all at a reasonable cost and I would highly recommend them.”
