THWhy Workers Put a Sponge Ball Inside Concrete Pipes 🤯
You might be wondering why this worker is putting a sponge ball into a concrete pipe.
After concrete work is finished, leftover concrete often remains inside the pipe. Over time, it hardens, builds up layer by layer, and can eventually block the entire pipe. Removing hardened concrete later takes a lot of time and effort.
So a simple solution is used. A sponge ball is flexible, meaning it can expand or shrink based on the pipe’s size. After the work is done, water is poured into the pipe, the sponge ball is inserted, and compressed air is released from behind.
As the sponge ball travels through the pipe, it pushes out all the leftover concrete and dirt — cleaning the pipe completely.
Sometimes, the simplest solution works best.
