Does the ground have to be 100% level?

Rinks can be built on uneven ground. The instructions in the Ice Rink Kit will show you how to level the border to compensate for the drop. It’s very easy to do – but the greater the drop from the high to the low side the more the preparation will be required. Backyard Rinks can have a maximum 10” drop from the high to the low point. We recommend that you measure the slope before you do anything. Check the slant, tilt, grade or drop of your yard to make sure that you selected the most level ground for your site.
