Insulated Slab Foundation Cost

Because they are easier to insulate slab foundations with stemwalls are preferable to monolithic slabs.

Insulated slab foundation cost.

A basement foundation is a minimum of eight feet above the footings and provides living and storage space. A floating slab for a mobile home runs 4 600 to 14 000 while a standard 24 x 24 2 car garage foundation costs 3 100 to 4 800. A basement foundation supports the entire structure. But in fact as foundations go it s quick and cost effective and provides an excellent base for the super insulated homes we build.

A typical 1 200 square foot house foundation costs 6 900 to 16 200 for a concrete slab or about 40 000 for a full basement unfinished. The added cost for additional floor insulation can be paid back in as little as a couple of years though energy savings. Increasing sub slab insulation to r15 or r20 or more will make floors much more comfortable and reduce heating costs. Slab foundation is the least expensive of the three foundations.

Labor for this foundation will cost about 7 000 for a total of 10 200. Two materials used to construct foundations are icf and poured concrete. In cold climates most slab on grade foundations include perimeter stemwalls or frost walls that extend 3 ft. Compared with a full foundation a frost protected slab can reduce construction costs in my market by about 20 000 for a house with 850 square feet on the first floor.
