Grinding out the temporary rapid strength concrete in the Oroville Dam Spillway. The grinders and equipment had to be craned in and out over the spillway walls and tied off with 1,000’+ of 1.25”-1.5” wire cabling. Grinding concrete up to 3″ on a 25% slope down hill required specific engineering for grinder production and safety capabilities. This was a time critical job and Anrak delivered the job early and under budget with the great efforts of everyone involved. An historic job in the history of Anrak!!!
