Does the ground have to be 100% level?
Rinks can be built on uneven ground. The instructions with the 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, the more preparation will be needed. Backyard rinks can have a maximum 10″ drop from the high to low side – “municipal” rinks can handle an 8″ drop. We HIGHLY recommend that before you do anything, you carefully measure the slope (slant, tilt, grade or drop) of your yard to make sure that you select the most level site.
