Tunnel washing is another application for which DeAngelo Brothers, Inc., utilizes its high pressure (3,000 to 5,000 PSI) heated hot water wash systems. We are equipped to perform all phases of this work, starting with all the traffic control equipment and devices needed to set any types of lane closures. Next we use high pressure heated water and biodegradable detergents with or without mechanical scrubbing devices to clean wall and ceiling areas. When working in environmentally sensitive situations, we have the ability and equipment to seal off drains, and collect and recycle all washwater.
