We have a project where they will build a sport court outdoor. The frost depth is 4 ft deep. The slab will be post tensioned slab on grade. I am just wondering what would be the best way to protect the slab from frost heave. They want this sport court to last for a long time. At first I thought they just wanted to do a typical outdoor slab on grade where movement does not really matter. The soil report suggested using 3 ft deep of structural fill. I was just wondering if I have other options perhaps using rigid foam or maybe concrete apron wall around the perimeter of the court that goes frost depth?
