It’s up to you when it comes to choosing material for our yurt base. There is not any proven correlation between expensive material and long lasting products as some of our customers used second hand material or even left over materials.
Mostly people used OSB or plywood (more OSB than plywood). Kingspan board is usually used as an insulation which goes in-between the OSB. You can finish up installing laminate flooring or carpet or even coir mat which you should do after assembling your yurt up.
Factors To Consider
Make a circular platform that is the same size as your yurt’s diameter then attach the bender board. We use plywood (5.5 mm) for the bender board. The outside of the bender board needs to extend down to completely cover all the layers and should be coated with weather treatment!
The base should be a few centimeters (more than 20cm) above the ground. It gives protection from strong wind, draft and rainwater.
To position your yurt to have as much sunlight as possible.
To position the yurt’s door facing away from strong wind exposures.
If you are building on blocks, make sure you are on a solid level ground, every block leveled evenly & securely.
Also, you need to consider how long your yurt will be kept up for before planning the base.
If your yurt is kept up for long periods, it is important to make a strong and flat base which raises your yurt above ground level, preventing any damp problems by allowing air to circulate beneath the yurt, helping rain water to easily run off.
If you use your yurt only for temporary usage, consider making a portable base which can be dismantled and kept in the storage.
In either way, your choice of materials and designs are up to you, depending on your budget.
