Frequently Asked Questions

What is the frost line depth in Idaho?

In the Treasure Valley, building codes typically require footings to be dug to a minimum frost depth of 24 to 30 inches to prevent winter heaving.

What is the difference between a monolithic slab and a stem wall?

A monolithic slab pours the floor and footings all at once in a single pour. A stem wall foundation requires pouring footings first, building cinderblock or concrete walls, and then pouring the slab inside.

Do you handle the excavation for foundations?

Yes, we provide full-service foundation prep, including trenching for footings, grading the pad, and compacting the gravel base.

What PSI concrete do you use for foundations?

We typically use a minimum of 3,000 to 4,000 PSI concrete for residential foundations and garage slabs, depending on structural engineering requirements.

How long does a foundation need to cure before framing?

While concrete sets quickly, you should wait at least 7 to 10 days before beginning heavy framing, allowing it to reach sufficient compressive strength.

Do you pour foundations in the winter?

Yes, but it requires special precautions. We use ground heaters, thermal blankets, and specific concrete additives to ensure the foundation cures properly in freezing temperatures.
