Mixing concrete is hard work. Here Chris and Connor are hard at work.

First the gravel mix is shoveled into 5 gallon pails - five shovels worth. Then the bonding fibers are added to the pail. The pails are carried down the hill and dumped into the mixing stations. One rounded shovel of concrete per pail is then added to the mix in the station. A station will take 2-3 pails of mix, depending on the energy level of the mixer, since the more mix, the harder it is to mix it!

Once the sand, pebbles, concrete and bonding fiber is dry mixed together, the mixer calls for water. Water is carried around in a 5 gallon pail and is added till the mixture is like "oatmeal" - sometimes it's thicker, sometimes it's thinner.

Once the concrete is ready to pour you either dump your station or wheel barrow and start all over again. Once the concrete is dumped there is a person or two responsible for screeding and tamping the concrete into a reasonably smooth slab and placing wall anchors in the slab along the edges and in the corners.

At the end of the day, no matter what job you had (shoveling, concrete, water, mixing, screeding), your arms are ready to fall off! But you feel good looking at that smooth slab of concrete.
