What is a concrete footing pad?
FootingPad is a patented code-compliant post footer used to support decks, post-frame buildings (pole barns) and other post supported structures. Easy to handle and use. Eliminates hauling, mixing and waiting for concrete. Made in the USA of 100% recycled material. Replaces concrete footings of equal diameter.
How deep should a footer be for a concrete slab?
Depth of Footings Footings should extend to a minimum depth of 12 inches below previously undisturbed soil. Footings also must extend at least 12 inches below the frost line (the depth to which the ground freezes in winter) or must be frost-protected.
What is a precast footer?
Precast Footings These piers come in round and square and are made from 4000 psi concrete with a 1/2 inch captured bolt provision. embedded in each footing is a (1) 1/2 inch rebar. Precast concrete piers are designed to be installed directly in the ground and will resist frost heaving.
How deep should pad foundations be?
The depth of a pad foundations are typically between 600mm – 2000mm but once the pad becomes too deep, it may not be economical anymore, and it may be better to use pile foundations.
Can I use concrete deck blocks instead of footings?
The acceptability of deck pier blocks instead of footings depends on two things deck height and frost level. Pier blocks can be used instead of footings for a ground-level deck not requiring permits. Piers blocks can also be used if the frost level depth is less then the height of the pier block.
Can precast concrete be used for foundations?
Precast concrete walls and foundations are made in a factory with high-strength, 5,000+ psi concrete. The concrete mix is poured into re-usable molds that are adjusted according to the blueprint specifications.
How do I know what size pad footing I need?
To determine the size of the footing, a simple formula is used: Structural Load (lbs) / Soil Capacity (psf) = Footing Surface Area Required (sq. ft.)
What type of soil is suitable for pad foundation?
Chalk soils can be prone to erosion, so be wary of the possible presence of hollows or caves. Dry, compact gravel or gravel and sand subsoils are usually adequate for strip foundations. Generally a depth of 700mm is acceptable, as long as the ground has adequate bearing capacity.
How are pad foundations constructed?
Pad foundations are a form of spread foundation formed by rectangular, square, or sometimes circular concrete ‘pads’ that support localised single-point loads such as structural columns, groups of columns or framed structures. This load is then spread by the pad to the bearing layer of soil or rock below.
