How do I thicken slab with 2″ of foam underneath?
I am building a house on a slab (with in-floor heat). There will be 2″ of blueboard underneath the entire slab. I need to thicken the concrete slab16″x8″x10 feet in the center. How do I do this and maintain the continuity of the insulation? Pour the pads first? Cut holes in the blueboard? Help, I start next week!
