Wild & Wonderful Dynamic Compaction

or How We're Using a Unique Solution in West Viriginia

How do you quickly and economically consolidate mine spoils deep in the scenic mountains of West Virginia for a new building site? Call Menard Group USA to mobilize their enormous crane on the remote site to perform dynamic compaction, of course! 

Along with general contractor Powell Construction and geotechnical engineers Geo-Mechanics, our crew recently completed a project at Kanawha Eagle River Mine in Winifrede, WV. We worked at the bottom of a deep excavation to provide dynamic compaction energy to mine spoils for densification. 

To keep to a very tight schedule, we also worked in close coordination with Powell to backfill craters created by the 12.5 ton weight dropped from our electronically-controlled Liebherr crane in three phases.

 


Now that our work is complete, the mine will be constructing a plate press building on the site where they'll be squeezing the moisture out of mine spoils before they deposit them on-site.

Is dynamic compaction an option for densifying soil on your next project? Let our experts assess the situation.

In case you need a refresher, Vibro Stone Columns are columns of compacted granular material installed in fine grained soils to increase the rate of consolidation but they are primarily used to improve the load bearing characteristic and stiffness of soft soils.

Our design Menerd, John Myers, got to work on a solution that allowed us to stiffen the soils and build the columns needed to limit the settlement for the warehouse. The Vibro Stone Columns generated significant schedule and budget savings over more costly augercast piles with large pile caps and thick structural slabs.
