Making Zero Concrete Stone Foundation

Building stone/granite foundation for our wood workshop with the help of our friends. The ground/base layer was done by 7 men in one day from 9AM - 6PM. From digging out the trenches down to 1.5 meters deep (below freezing level). Then filling them with larger stones at the bottom and then layer with silica sand, and then another layer of stones, sand and water - to compress the sand and fill all the gaps between the stones until reaching the ground level. The top layer was masoned from split recycled stones (from an abandoned building) using traditional lime and rye flour mortar.
