Coarse Washed Aggregates – BoDean

Coarse washed aggregates are typically chosen when rock needs to be clean. Washing aggregates removes clay, dirt and debris from the rock. Once taken from the mountainside, the aggregate is taken to the BoDean Co. Wash Plant where it is cleaned with high powered jets and sorted into a variety of sizes for customers to select form.
