What is a Slab Foundation? Pros and Cons of Slab

A slab foundation is a large,thick slab of concrete that is typically 4-6 thick in the center and poured directly on the ground all at one time.The edges of the slab are thicker (as wide as 24) in order to allow for extra strength around the perimeter.User rating 5/5People also askHow are slab foundations constructed?How are slab foundations constructed?First,a definition is in order A slabfoundation is created by digging about a foot or so into the ground where the house is to be located,pouring concrete into the hole and reinforcing it with steel bars.The house is then constructedon top of this concrete foundation.The Pros and Cons of Buying a House on a SlabTanks - Michigangravel foundation with retaining ring.Concrete slab foundation costs an additional $5.00 to $6.75 per cubic foot.Add wood cover,joists,and ladders to basic tank cost as necessary.GALVANIZED STEEL TANKS Costs are averages of 13- to 20-gauge,coated,corrugated steel tanks,installed or erected on the buyers foundation.Prices include
