Prepping A Basement Slab For Inspection

The new house we’re building is absolutely flying. We’re almost ready to pour the basement- here’s everything I need to do to get the slab inspection. First, we’re required to put 4’ x 8’ sheets of 2” foam around the walkout section of the basement. Because this part of the basement will be above ground- this foam is required for insulation. The top of the foam is level with the gravel, so there’s room for the 4” concrete slab. Next, the plans called for a thickened slab under all the load bearing walls. We dug out extra gravel in these areas so the slab will be 8” instead of 4”. Time for the vapor barrier- We’re using 10 mil poly. Code requires a 6” overlap. I like to go at least a foot and tape down the edges. Finally, I put rebar in the thickened slab areas. I cut up slab bolsters to use for chairs. They have a plastic coating on the feet, so rust won’t spread from the ground up into the rebar. The plans call for 2 pieces of ½” rebar under each load bearing wall. I throw a few scoops of gravel on top, so the wind won’t blow up the poly. We’re planning to show the basement pour, like and subscribe so you don’t miss it. @hausplans #build #howto #construction #diy #contractor #basement #concrete #slab
