⚒️ @ Work 2024 On The 417 Highway In Ottawa Fixing The Wall Chipping Off All The Rust 🪖

Concrete chipping is a process which requires trained chippers or a robotically-controlled machine with an ultra high pressure water source (20,000 psi) to enter the drums of ready-mix concrete trucks and central mixers to break away the dried concrete along the drums’ walls. Human teams use tools such as the handheld jackhammer and chisel to manually remove hardened material. [1] The robotically controlled machine removes the dried concrete by cutting the concrete with ultra high pressure water, causing the concrete to delaminate from the interior of the mixer drum. The robotically controlled machine is operated by a human outside of the ready-mix concrete drum. Human teams, with help from shovels, wheelbarrows and the like, then pile the discarded concrete on the ground, where it can either be hauled away to the landfill, turned into new building material through the process of concrete recycling or repurposed in some other way. Mike Rowe, host of Dirty Jobs on the Discovery Channel, once described concrete chipping as the toughest job he ever took on.
