Concrete Block is Economical
Concrete block foundation systems offer the greatest long-term savings, even where first-cost investment is considered. Whereas cast-in-place concrete wall systems have additional reinforcement requirements and demand more detailing and on-site inspections, design and construction requirements for block foundations are minimal. Block masonry is constructed straight, square, plumb and level, making above-grade framing and interior and exterior finishes easier to complete.
In short, block is simple, convenient, and versatile to use. Together these factors help shorten building times and ultimately reduce construction costs.
