In a location where soil instability could have resulted in ash flowing into a nearby river, Hayward Baker provided an innovative solution that improved soil conditions to prevent pollution during a seismic event.

Geo-Foundations, a subsidiary of Hayward Baker Canada Ltd., becomes the First Specialty Foundation and Ground Improvement Trade Contractor in North America to achieve the certification for the OHSAS 18001:2007 international standard for workplace health and safety.

Hayward Baker Inc., North America's leader in geotechnical construction, was recently awarded a contract for the New Atlanta Stadium project. The new stadium, expected to open in 2017, will be the Atlanta Falcons home and will also be hosting sports, entertainment and convention events. The project includes the design and construction of Vibro Piers to support isolated column foundations and load bearing continuous wall foundations. 

Hayward Baker has recently started a significant ground improvement project in the K-10 South Lawrence Trafficway (SLT), providing its expertise in the specific project,which is a top priority for the Kansas Department of Transportation (KDOT). The project involves the combined use of wick drains and stone columns for the acceleration of consolidation and the stabilization of specific embankment areas. 

Extensive ground improvement works on the Ohio River Bridges Project (Downtown Pursuit) along Interstates 65 and 64 in Downtown Louisville, are being executed since June 2013 by Hayward Baker. The project involves ground improvement for 42 retaining walls and embankment structures and is carried out for the Kentucky Transportation Cabinet and the Indiana Department of Transportation, which are joint owners of the transportation investment. 

Students from the University of Michigan who are taking this semester the graduate level course CEE 542 on “Soil and Site Characterization” have prepared their class projects on “Select topics in Ground Improvement” online. Instead of having students prepare a class project report to himself, Prof. Zekkos, the instructor of the course, asked students to work in teams and prepare a project on the Internet. The student deliverable is now available to be read, reviewed and edited by research experts and experienced professionals!

Mechanically-stabilized earth walls and earthen roadway embankments supported on improved ground are part of the new bridge and interchange modifications for I-65, I-64 and I-71. Hayward Baker has been performing ground improvement work on the Ohio River Bridges Project (Downtown Pursuit) along Interstates 65 and 64 in Downtown Louisville since June 2013.  The project is being performed for the Kentucky Transportation Cabinet and the Indiana Department of Transportation, which are joint owners of the roadway infrastructure.
