Quick Answer
For effective yurt foundations, consider using a gravel base, a pier and beam system, or a slab foundation, as they can provide stability, drainage, and durability.
Choosing the Right Foundation Type
When it comes to yurt foundations, there are several options to consider, each with its own set of benefits and requirements. A gravel base is a simple and cost-effective option, consisting of a layer of compacted gravel beneath the yurt. This type of foundation works well on level ground and can be built on a slope, but it may not be suitable for areas with high water tables or unstable soil.
Designing a Pier and Beam System
A pier and beam system is a more permanent and durable option for yurt foundations. This type of foundation consists of piers sunk into the ground, supporting a beam that spans the piers and provides a solid base for the yurt. The piers should be spaced 6-8 feet apart, depending on the size of the yurt and the load it will be carrying. For example, a 12-foot yurt might require piers spaced 8 feet apart, while a 24-foot yurt might require piers spaced 12 feet apart.
Building a Slab Foundation
A slab foundation is a solid, monolithic base made of concrete that provides a smooth and level surface for the yurt. This type of foundation is ideal for areas with high water tables or unstable soil, as it can help to prevent water damage and settlement issues. To build a slab foundation, start by excavating a trench around the perimeter of the yurt site, then pour a layer of compacted gravel to provide drainage. Next, pour the concrete slab, making sure to include rebar to add strength and durability to the foundation. The slab should be at least 4 inches thick, and the yurt should be centered on the slab to ensure proper weight distribution.
