The first of these is to build a stem wall of concrete blocks up to the desired slab level.
Stem wall concrete slab foundation.
This type of foundation is much more stable when fill dirt is required achieve the final build elevation.
There are several stages to the construction of a stem wall which begins with cinder blocks that are reinforced with steel rods and concrete.
Then the fill dirt is added and compacted.
Depending on the building the stem wall is usually built to the height of three cinder blocks.
The key difference in this build type is the use of stem walls.
The stem wall on a concrete foundation is essentially the supporting wall that joins the foundation of a building to the vertical walls of the structure that is constructed atop the foundation.
The stem wall transmits the load of the structure to the footing which distributes the structure weight over a wider area.
A trench is excavated around the foundation for the construction of the stem wall.
This process takes a bit longer than the monolithic slab but a more stable foundation will prevent other issues down the road that could arise with trusses or wall construction.
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.
Finally a slab is poured to the desired level.
