Stoops in the south
Stoops in the south
(OP)
Hi,
In the north we design all of our exterior doors with stoops that have frostwalls and footings that extend 4'-0" below grade. We are preparing a design build proposal for a building in Oklahoma. How are stoops typically designed/built there? I am told that the frost depth is about 22" in the area we are looking at.
Thanks!!

What is a frost block? I would go for anything that is less expensive than a full blown stoop with frost walls. Thank you!!

The construction can be concrete, lean concrete or clean rock fill. Frost walls around the outside really only hold down any frozen soil in the "cube" underneath the slab, since the cold can still penetrate through the topping slab. Frost walls are effective and often used in my experience where frost depths get up to 4 ft or more (you know who you are North Dakota).
In Missouri we often use clean rock 30" deep and then pour our sidewalk over the top. The problem mostly comes in as a high cost where you have a spec retail center where you don't know where the doors are.
