Structure notes

1. If you build on bedrock in frost area, frost is not an issue and you don't have to put footings down below the frost line.
2. If you build on gravel or coarse sand that is free-draining, and the water table it far enough down, frost isn't likely to be a problem.
3. It is important to understand that once you dig a hole and make a basement, you have got to keep the building heated. As long as we keep the inside of the building heated, frost can't get down under the basement floor.
4. An unheated house allows frost to penetrate the soil 3 to 4 feet under the basement floor. If there is adequate moisture in the soil, it will heave, picking the house up with it, or commonly, parts of the house.
