Strap footing is a cost-effective and efficient solution for designing a spread footing. It is a type of foundation system which uses a combination of two or more individual footings that intertwine and join together. This configuration of footings is especially useful for supporting large loads, such as those from a structure, due to its strength and stability. The footings are typically connected with steel straps, which act to transfer the load between the two footings, thereby creating a larger, more stable footing. It also allows for the use of smaller footings than what would otherwise be required, thus saving costs in terms of materials and labor. Additionally, strap footing can be used in areas with poor soil conditions, such as on sloping ground, as it provides a more even distribution of the load.

Strap footing is a type of foundation system used in building construction. It is also referred to as a strap beam foundation or a bent cap beam foundation. This foundation design consists of two walls of reinforced masonry or concrete blocks that are connected with a reinforced concrete beam. The walls, which may be 3 to 4 feet high and up to 4 feet thick, are connected to a concrete footing and the beam which is similarly reinforced. This creates a bridge, known as the strap footing, connecting the walls of the structure. The purpose of the strap footing is to provide stability for the walls of the structure, allowing for more efficient use of the ground space and allowing for the construction of taller structures.
