Segmented footing system evaluation
Foundation construction for spread wall footings normally involves constructing formwork, placing reinforcement, and pouring and curing concrete, regardless of footing size or the amount of anticipated load. Recently, the National Concrete Masonry Association (NCMA) has developed a complete foundation system called the Footer Block system. It was designed to reduce the costs of foundation construction for 1 and 2 story buildings. The footer black system consists of interlocking concrete blocks 10.2 x 40.6 x 20.3 cm (4 x 16 x 8 in). Because they are placed with no mortar, delays associated with the curing process or providing access for concrete are unnecessary.
