Registration

Come join us for a thought-provoking and entertaining evening based on great food, outstanding company, and stimulating conversation. Our speaker for the evening will be Mr. Mike Cowell, P.E., President of GeoStructures, who provides engineered earth structures and ground improvement technologies in the Mid-Atlantic region on a design/build basis. Mike holds an M.S. degree from Cornell University in Geotechnical Engineering and a B.S. degree in Civil Engineering from Clarkson College.  Prior to founding GeoStructures, Mike was Vice President at the Reinforced Earth Company, General Manager at the Tensar Corporation and a geotechnical consultant for Golder Associates and Law Engineering. 

Mike’s talk will address:

 

 

Ground Improvement - The Next Generation

While it has been over 15 years since the last major breakthrough in ground improvement – Geopier Intermediate Foundation Systems, - Geopier is now more than just an aggregate pier. The technology has advanced over the last 10 years to include:

 

         Displacement Aggregate Piers

         Grouted Aggregate Piers and Cement-Treated Aggregate Piers

         Geo Concrete Columns

         Armorpact – geosynthetic shell piers

         Densipact - insitu compaction of sands

         Soil Reinforcement Technology

 

And there is still a lot of R&D in the wings…..

   

The tried and true aggregate pier ground improvement technologies still have their place. However, ground improvement methods have had to change in order to keep up with larger structures, heavier loads, and greater seismic design requirements.

 

The talk will cover why the next generation of ground improvement technologies was developed, how they work, and how they have been applied through case studies involving projects ranging from ground improvement on transportation projects for support of MSE walls and highway embankments, to water treatment plant tanks, heavily-loaded industrial floor slabs, rail spurs, and commercial buildings with high column loads and adjacent footing stress overlap issues.
