Can you build on concrete slab in cold climates? Slabs for Colder Climates, Part 1: The How and Why of Frost-Protected Shallow Foundations. As energy savings and the conservation of resources increasingly drive decision-making for homebuilders, frost-protected shallow footings offer a good method for constructing slab-on-grade foundations.
Can you use a slab foundation in cold climates? In cold climates, a slab-on-grade can easily avoid frost heave with the simple addition of skirt insulation, which protects the perimeter of the footing so that it will never be subjected to the freeze/thaw cycle, and instead remain close to the relatively constant 8 -10 degrees Celsius temperatures of the earth.
Why can’t we build slab on ground foundation in the area with cold climate? But slab-on-grade foundations can be extremely vulnerable to frost damage. Clay soils (like those of northern New England) are typically saturated with ground water. When this trapped water freezes, the soil expands. If this expansion were uniform, it would pose no appreciable threat to a slab-on-grade foundation.
What foundation is best for cold climate? A frost protected shallow foundation is a practical alternative in cold regions with seasonal ground freezing and the potential for frost heave, saving customers time and money. Standard foundation footings are typically placed below the frost line, which is about 4-feet deep in the northern United States.

How to do concrete patio over grass?

Typically we like to limit the weight to about 40 lb/sqft on an unknown 4″ slab. In most cases you can go to 80 lb/sqft in isolated spots, but unless you know roughly what the soil bearing and reinforcing is for that slab you might be looking at cracking.
