For roof loads of 40 psf or greater, a professional engineer or registered architect must determine the maximum mating wall opening permitted without pier or other supports.ĥ. Place piers on both sides of mating wall openings that are 48 inches or greater in width. Piers are not required at openings in the mating wall that are less than 48 inches in width. Single stack concrete block pier loads must not exceed 8,000 lbs.Ĥ. in either direction along supported members to allow for plumbing electrical, mechanical equipment, crawlspaces, or other devices.ģ. Bottom of footings must be below the frost line depth, unless designed for placement above the frost line.
Pier support locations and spacing must be presented to be consistent with Figures A and B to § 3285.312, as applicable, unless alternative designs are provided by a professional engineer or registered architect in accordance with acceptable engineering practice.ġ. (c) Piers supporting the frame must be no more than 24 inches from both ends and not more than 120 inches center to center under the main rails. (b) Mate-line and column pier supports must be in accordance with this subpart and consistent with Figures A through C to this section, unless the pier support and footing configuration is designed by a registered professional engineer or registered architect. Immediately after leveling the surface, align and inset any deck hardware and then smooth the surface of the concrete.Īllow the concrete to cure for one day before constructing your deck or placing heavy weight on the footing (if standard concrete mix was used, wait about 3 days to begin construction).(a) The location and spacing of piers depends upon the dimensions of the home, the live and dead loads, the type of construction (single-or multi-section), I-beam size, soil bearing capacity, footing size, and such other factors as the location of doors or other openings.

It's important to realize that the little bit of concrete will be a wise investment as you only get one chance to install the footing. After half of the form is filled, consolidate the concrete with a piece of rebar or a shovel to eliminate voids and air pockets.Ĭontinue to add concrete until the form is overfilled slightly. A house footing should be no less than 12 inches wide. TIP: it is best to use the uncut end of the tube for the top of the footingĪdd the concrete mix to the form. Footings and foundations, unless otherwise specifically provided hereafter, shall be concrete and extend below the frost line which is hereby declared to be.
Place the QUIK-Tube into the hole and level the form. Measure and mark the QUIK-Tube for the hole depth and use a handsaw to cut the tube to length. Footings typically must extend below the frost line to prevent shifting during freeze-thaw cycles.ĭig footing holes about 6 inches deeper than required.įill the bottom of the hole with 6 inches of gravel and compact the gravel with a 2x4 or wood post. NOTE: it is important to check local building codes for construction requirements in your area these requirements will include minimum diameter and minimum depth of the footings. If a soils report is required the footing trench bottoms are to be excavated to the depth required by the report. Soft areas including fill must be excavated until suitable bearing soil is exposed. Decks and other permanent structures require deck supports and footings made from structural strength concrete mix. Footing trench bottoms shall be level and a minimum of 18 below grade (frost depth). When working with cement-based products, always wear eye protection and waterproof gloves.Įnsure a solid footing.
