Foundation footings are the structural members that transmit the concentrated loads of the structure to the soil. Foundation footings come in various shapes and sizes and are generally constructed of steel-reinforced concrete. The footings are generally a minimum of two to three times wider than the width of the foundation wall. The thickness of the foundation footing is a function of the weight of the structure above and the strength of the soil below the footer. A thicker foundation footing (10 -12") will be stronger than a thinner (6 - 8") foundation footing. The footer is usually installed immediately after excavation. The foundation is then constructed on top of the footer. Generally speaking, the foundation footing is constructed independently of the foundation.
Foundation footings act as the base of a house's foundation and transmit the superimposed load to the soil. The type and size of foundation footings should be suitable to the soil condition, and in cold climates the footings should be far enough below the ground level to be protected from frost action, this depth being established by local building codes. Poured concrete footings are more dependable than those of other materials and are recommended for use in house foundations.
is a three-in-one concrete foundation footing form system, foundation drainage system and sub-slab perimeter radon reduction system. Polyvinyl chloride (PVC) lineal sections are used in place of wood or aluminum to form the foundation footing and remain in place after the concrete is poured. This saves time and money as there is no need to return to the jobsite to strip, clean and transport footing forms for reuse. After installation, Form-A-Drain
collects groundwater through multiple side vents and transports it to a sump pit or a drainage pipe to divert water out of the home. Harmful radon gas is also collected and safely evacuated through a separate vent pipe.
