Quick Answer
For uneven terrain, a gravel pad foundation works best, allowing for drainage and minimizing soil settling issues. This type of foundation can be created with a compacted gravel base, often 2-4 inches deep, topped with a sand layer for extra stability. A yurt's base should be level to ensure proper roof structure support.
Choosing the Right Gravel
When selecting a gravel for the pad, go for clean, angular stones with a mix of coarse and fine particles. A 3/4-inch to 1-inch crushed gravel is ideal, as it compacts well and provides adequate drainage. A 2-inch deep layer of compacted gravel is sufficient to support a yurt.
Preparing the Site
To prepare the site, first clear the area of any debris and vegetation. Then, mark out the yurt’s footprint using stakes and twine, allowing about 1 inch of clearance around the yurt’s base. Next, dig the area to the required depth, about 6-8 inches below the final pad height. This will help prevent soil settling issues.
Compact and Finish
Compact the gravel base using a plate compactor or hand tamper, ensuring it’s level and even. Add a 1/2-inch to 1-inch sand layer on top of the gravel for extra stability and drainage. Finally, smooth out the sand with a level and a rake, and your gravel pad is ready to support your yurt.
