Please briefly elaborate on the hydro blasting (w/ blast media), by which you had reduced the dust generation and waste disposal, for our use.

Some typical methods for high pressure blasting include:
1. Hard and Soft Water Lancing: These are small diameter hoses or tubing with spray nozzles attached. They are used to clean small diameter orifices such as heat exchangers, bundles, and small pipes.
2. Shotgun Blasting: Shotguns are hand held and operated spray nozzle used for general cleaning, de-coating, structural cleaning, and tough concrete cleaning jobs.
3. Water Jetting: Water jetting uses larger diameter hoses and spray nozzles. The nozzles are self-propelled by aiming more of the water pressure backward and less forward
4. Abrasive Cutting: Abrasive cutting uses very high pressure water and an abrasive to cut through steel and concrete (including rebar). It is the slowest and most expensive method of cutting. It value is that it is spark free and can be used where flammable conditions exist.
Waterblasting was more expensive than sand blasting but, can save time and cleanup efforts.
