Background A frost protected shallow foundation (FPSF) is a practical alternative to a deeper, more-costly foundation in cold regions with seasonal ground freezing and the potential for frost heave. Heat input to the ground from buildings effectively raises the frost depth at the perimeter of the foundation. Heave precautions are not required for proposed trees as the soil has not been desiccated and therefore heave cannot take place.
