Compared to traditional demolition and concrete removal methods for infrastructure repair and rehabilitation projects, hydrodemolition is much more capital intensive. Machines do the work of several workers, and mechanized, robotic units reduce labor and minimize injuries compared to chipping hammers.
Rampart Hydro Services has the capacity to rapidly design machines that remove concrete where humans would otherwise have difficulty. For example, on vertical and/or high surfaces where workers must hold and control heavy equipment, like jackhammers. Work in these conditions can be very dangerous for people to perform safely.
While hydrodemolition involves water, with proper control, it is not particularly messy, especially when Dry Hydrodemolition® methods are used. During Dry Hydrodemolition, the wastewater is vacuumed immediately after it demolishes the concrete. Dry Hydrodemolition® adds an additional layer of safety to bridge deck concrete removal because it keeps the water from running into live traffic lanes.
Because it is wet, hydrodemolition has an enormous health-related benefit: it eliminates dust and the potential for silicosis and other respiratory illnesses to workers. OSHA began enforcement of the new Respirable Crystalline Silica construction standard (OSHA 1926.1153) on September 23, 2017. The primary Engineering and Work Practice Control method specified by OSHA is the use of water to suppress the silica containing dust particles. Hydrodemolition already accomplishes this with no additional equipment needed.
Another major jobsite safety issue is shielding and protection. Proper shielding and protection is critical to jobsite safety and security. Flying debris can easily break windows, dent or damage passing vehicles, or injure individuals.
