Stem Wall Concrete Slab

This type of foundation has special requirements for horizontal and vertical dowels or bars.

Stem wall concrete slab.

The structures require three components for their construction a poured slab a foundation. Stem wall slabs are constructed in a multi part process where a footer is poured at virgin ground level then blocks are laid forming a wall up to the finished slab elevation. A built wooden wall will protect the exterior side of the stem wall. Stem walls are structures that are used to connect the foundation of a building to its walls.

Depending on the building the stem wall is usually built to the height of three cinder blocks. The slab subfloor must be several inches thick. This is done at the same time as the concrete slab that tops the foundation. Each row of cinder blocks is laid in turn before the concrete is poured.

They are made from rows of concrete blocks sometimes from bricks and are reinforced with steel components and works together with the foundational slab. If extra footings are required add 6 53 per square foot to the cost. Stem walls are supporting structures that are used as a means of joining the foundation of a building with the vertical walls constructed on the foundation. Predominantly constructed concrete footings with masonry walls they rise above the ground level to provide a raised platform for placing the building slab.

A monotlithic slab foundation also known as a slab on grade foundation combines the footing stem wall and a concrete slab subfloor in a single pour. The total cost depends on the size condition of the soil location and whether it s a monolithic slab stem wall slab or a raft foundation. This type of foundation is much more stable when fill dirt is required achieve the final build elevation. The wall is often constructed with the use of concrete and steel and works with the foundational slab to create a solid basis for the building.

The average cost to build a 1 350 square foot concrete slab foundation for a one story home is 8 600.
