Our Operation  Rock Solid Rock recently added two monster machines to our growing equipment fleet.  In August 2006 we added a Volvo L120 Wheel Loader that has made the moving and loading of the processed shell three times faster than before.  In September we added a Volvo EC700 Excavator, the largest machine and only machine of this size in operation in the state of Florida. This excavator moves through the coquina rock shell without hesitation allowing us to increase our rock production as well as shell.
