How Do You Build A Stone Foundation?
• Dig a perimeter trench along the boundaries of your proposed building. The trench should be about 1.5′ wide, and deep enough so that it’s below the frostline. Use a pick/mattock to break up the soil, and a transfer shovel to shovel it out. The soil can be used as fill to build up the grade within the foundation, or outside it to slope the land down and away from the dwelling. When the trench depth is roughed out, use a square-ended shovel to scrape the bottom, so that the floor of the trench remains packed and undisturbed. • Set in the largest stones first. If you have boulders, or something like these hardened quickcrete bags to use, lay them in the bottom of the trench like this: • Continue to set in the largest stones you can lift and fit in the trench. The stone should get progressively smaller as you fill towards the top. • Pack it tight. Everything should fit like a puzzle – pound rocks in with a hammer where you need to. Urbanite can also be used, and torn up asphalt sections
