Quarry Development/Contract Mining

Allied Rock can offer quarry owners and contractors technical services for quarry and mine planning and development.  Our skilled team will listen to your needs and then guide and advise the most cost-effective option for your site. 

Once a plan has been developed our experienced field crews will then execute that development plan.  Our vertically integrated operations allow us to perform all facets of development, in-house, with MSHA Part 46 trained employees, including; timber felling, clearing & grubbing, overburden removal, dumpsite preparation, contract mining, and more.

ODOT Testing Lab

Allied Rock maintains a fully equipped and ODOT certified aggregate testing lab.  We perform all testing in-house with our on staff CAgT technician.  This allows us to quickly and efficiently calibrate our crushing plants to produce rock which meets contract specifications.  Test results are available for the variety of products we make.
