Where do footings go in a basement?
Footings lie under the basement, crawlspace or stem wall and transfer structural loads from the building to the supporting soil. Footings are typically cast-in-place concrete, placed beneath the frost depth to prevent damage resulting from heaving caused by freezing of water in the soil.
What is a foundation pier?
Foundation piers (see Figure 7) are isolated structural elements used to support the building above. Structural design ensures the piers are sized and spaced to carry the necessary building loads. Piers typically are in enclosed crawlspaces, so recommendations for moisture and soil gas resistance for crawlspaces should be followed for piers as well. Building Code Requirements for Masonry Structures (ref. 7) requires a foundation pier to have a minimum nominal thickness of 8 in. (203 mm), with a nominal height not exceeding four times its nominal thickness and a nominal length not exceeding three times its nominal thickness. Note that the International Building Code, (ref. 8) allows foundation piers to have a nominal height up to ten times the nominal thickness if the pier is solidly grouted, or four times the nominal thickness if it is not solidly grouted.

BASEMENT WALLS. Basements are typically built as conditioned space so that they can be used for storage, work or living space . Because of this, water penetration resistance is of paramount importance to basement wall design and construction.
Where is the foundation drain located?
The drain should be placed below the top of the footing. The optional footing drain shown, such as 2 in. (51 mm) PVC pipe at 8 ft (2400 mm) on center, allows water on the interior to reach the foundation drain. Footing drains can either be cast into the footing or constructed using plastic pipes through the bottom of the first course of masonry, directly on top of the footing.
Do you need to waterproof a stemwall?
Because the wall is exposed to soil on both sides, waterproofing or dampproofing coatings are generally not required. Stemwalls are typically insulated on the exterior of the masonry. If insulated on the interior, it is important to place insulation in the joint between the slab edge and the foundation wall to avoid thermal bridging.
