Can you recommend the best method of building an insulated slab on grade suitable for the laurentian mountains in the event that bedrock prevents digging out a foundation? On your site, you discuss Frost Protected Shallow Foundation - or FPSF., 8 inches Rockwool rigid board under the exterior of the slab, Tpye III EPS foam under footings and a skirt of R8 insulation extending out 4 feet. ARe these suitable for such conditions. Have these materials been tested to see if they retain their insulating properties over time?? If not, the concrete slab will heave, crack, etc. Also, do you have a list of foundation contractors who have experience with building these slabs?
