Super Insulated Slab Foundation

Alternatively we ve used a 11 2 inch layer of flowable fill a thin aerated concrete mix with sand aggregate to true the surface.

Super insulated slab foundations a thick layer of foam on a bed of compacted gravel supports the building prevents frost damage and keeps the heat inside by alan gibson. In colder climates achieving the necessary r value below a slab floor requires between 8 and 10 inches of expensive extruded polystyrene or high density expanded. This material is a dimpled 24 mil high density polyethylene that provides wall and under slab moisture control for all types of foundations and isolates living spaces from floors that otherwise can become damp. Slab on grade floors tend to have fewer air leaks than wood frame floors although plumbing penetrations must be sealed.

It s better to block out crawl space vents in the foundation wall where they will not interfere with insulation. To prevent voids under neath the foam which might cause it to deflect we take extra care to level the compacted gravel.
