This Pipe Will Clog in 90 Minutes Without This

Concrete starts hardening the moment it's mixed, and if it solidifies inside a pump pipe, you're looking at a $10,000 repair bill. That's why workers use these massive sponge balls called "cleaning pigs" to blast through hundreds of feet of pipeline after every pour. The operator listens carefully, tapping the pipe with a hammer to confirm the cleaning pigs made it through safely. One skipped cleanup = one very expensive clogged pipe. #concretepump #construction #satisfying #concrete #heavyequipment #constructionfails #engineering #howthingswork #construction101 #didyouknow
