The method has been in use for more than 50 years in northern Europe. Concrete strength: 2,500 psi minimum, but up to 3,000 psi may be required. National Oceanic and Atmospheric Administration Builders should know the ABCs before beginning a FPSF: the minimum depth for a FPSF in that climate zone, the minimum insulation requirements, and whether the insulation will need to be only vertical on the face of the foundation and footing or vertical with horizontal extension from the perimeter (see Figure 2 below). Surface Observations All of this does increase the cost and complication of using the FPSF method, so you will run a cost comparison to see if it makes sense on your project.
