Yurt platform on grade versus sunken piers

[Bob Rowlands]

Look around the building site that should tell you. If there is evidence of frost heaving where you are siting the yurt, and you want a level platform for the long term, then placing piers below frost level would be a wise option.

If not, then block piers will be fine. Be sure to install rebar pins in the core mud. Definitely fill the cores with mud. Don't skip that step to save a few bucks.

To my way of thinking, yurts are transitory structures. That's one of the beauties of the design. Considering such, I wouldn't go to thousands of extra in expenses, unless the ground heaved every winter. Good luck.
