Houston-based Campbell Concrete & Materials LLC is the premier North American user of the DrumBlaster Daily Washout System. Developed in Australia, the equipment combines a narrow, elevated booth from which mixer truck drivers or station operators activate a telescoping 8- or 10-meter boom, tipped with multiple jets directing water at 300 psi to blast residual concrete from drum wall and fins. In typical plant operations, the boom is set for two three-minute passes.
