Found these videos and felt like sharing them here. They show some pretty good team work by these construction workers from other parts of the world. Really hard workers.
The techniques are pretty cool and could easily be used in earth construction methods as well if needed.
I remembered a friend that had years of experience in construction in Uruguay, telling me how he had this worker that could plaster a wall using a shovel! He’d pick up some concrete and throw it against the wall as if his shovel were a huge trowel, speeding up the process a lot. It must take a lot of muscle, technique and practice to achieve that, the trowel can be hard enough. I searched for a video of something like it, but didn’t find one.
