I helped a friend with a basement bathroom project and he needed a hand filling in the holes in the slab where the new plumbing had been installed. On the day of the pour, he was conveniently stuck working late. I decided to continue the pour myself since the Rapid Mixer works well with one or two people. I won't say the the last 4 bags were as easy as the first 5 but the whole job was completed in just over 30 minutes.
The video below is a time-lapse of the pour.
