(Not if we can help it!)
To prevent frost heaving of uninsulated shallow foundations, building codes in many regions specify that foundations extend below the frost line, requiring additional excavation and concrete. Avoid this extra step - and meet code - by insulating the shallow foundation with STYROFOAMâ„¢ Brand Extruded Polystyrene Insulation. And save time and money while you're at it.
See ASCE Design & Construction of Frost-Protected Shallow Foundations. International Code Section R403.3. For more information, visit http://www.nahb.org.
