About Us

Who We Are

We founded R. Dorian Heavy Hydro in 2018 because we knew manual chipping wasn’t sustainable. It’s dangerous for the worker and a liability for the employer. OSHA’s new rule that sets the Personal Exposure Limit (PEL) to 50 µg/m3 means it’s time to explore other solutions for cleaning concrete mixer drums. Hydro blasting is a safe, cost-effective alternative to manual chipping.
