03 Concrete, Block, Brick, & Stone – Preview
Type of foundation wall
For several decades in the middle of the 20th century, concrete block (CMU) foundation walls were very common. Since then, Poured Concrete has become more popular for new homes. Alternatives to Poured-in-Place Concrete foundation walls include both Insulated Concrete Forms (ICF) and Precast Concrete Systems. Advantages of these two alternatives include increased thermal and moisture resistance. Verify if there are local installers who have experience with either of these systems if you are interested. Also research the relative price well in advance of the construction phase.
Select your foundation wall:
__ CMU (Concrete Masonry Unit, often referred to as concrete block)
__ Poured-in-Place Concrete
__ Insulated Concrete Forms (ICF)
__ Precast Concrete System ( ie. Superior Walls)
The quality and precision of the foundation walls are critical to the rest of the project. Review the desired elevation of the top of the foundation wall, relative to ground and finished floor, with the contractor before work is begun
Temporary Measures & Protection of Existing Building
Backfill shall not be placed against the wall until the wall has sufficient strength and has been anchored to the floor above, or has been sufficiently braced to prevent damage from the backfill.
