Improperly built decks can shift or collapse, injuring people in the process and causing damage to houses and other structures. Building codes are in place to ensure safety, and virtually every state and municipality enforces codes for deck construction. Most jurisdictions follow the International Building Code, which devotes one section—R—to deck construction.

Some building departments also publish their own codes which may differ somewhat from the IRC. The first step in deck construction is to draw up a plan, and the second step is to submit that plan to the local building authority and obtain a building permit. After construction of the deck, you must get it inspected to ensure compliance with applicable codes. If you aren't working with a contractor familiar with the codes, it's a good idea to study section R of the IRC as well as the codes published by your local building department.

Some requirements may surprise you, and if you fail to follow them, your deck won't pass inspection. After you've laid out the perimeter of the deck, it's time to set the footings, which support the posts that in turn support the deck. Each footing must be capable of supporting 1, psi load pressure, and the code specifies minimum width and thickness depending on the beam and joist span.

You can size your footings by consulting Table R For example, if you're installing square footings, they will have to be at least 21 inches wide and 9 inches thick if your beam spacing is less than 8 feet and the joist span is between 14 and 18 feet. Circular footings, on the other hand, need to be 23 inches in diameter. The footing sizes also depend on the load-bearing capacity of the soil and the live load the deck must support. Footings need to be at least 12 inches below settled soil to prevent lateral movement.

In addition, they need to be dug below the frost linewhich varies according to climactic zone. In Florida, where frost seldom occurs, some local authorities may allow you to place your footings on grade, but in cold states such as Minnesota, you may have to dig down 48 inches or more. When setting footings on a slope, the rule of thumb is to dig them at least deep enough so that the horizontal distance from the bottom of the hole to ground level on the downward slope is at least 7 feet.

This depends on the soil characteristics, however. When in doubt, consult with a soil engineer before digging. Any wood incorporated into a deck structure that is in ground contact must be treated with a preservative to protect it from decay, and it must be labeled as such. Commercially available pressure-treated wood fulfills this requirement, and most builders use this type of lumber for the entire infrastructure of a deck. Posts must be attached to the footings with appropriate fasteners to prevent lateral movement as well as uplift.

You do not have to use fasteners, however, if the post itself is buried to a depth of at least 12 inches. If you set the posts on top of concrete footings, even precast ones, you must secure them with positive hardware connections. You can use 4 x 4 posts up to a maximum length of 10 feet and 6 x 6 posts up to a maximum length of 18 feet.

The IRC no longer allows the use of dimensioned 4 x 4 or 6 x 6 lumber for the beams or girders that rest on the posts and provide the support for the joists.

Instead, your beams or girders must use multiple layers of 2 x material. For instance, instead of using a 6 x 6 beam, you can fasten together three layers of 2 x 6 lumber. The size and span of the beam you need depend on the span of the joists they support.Summer is upon us and the outdoor living season is in full bloom.

In neighborhoods all across the country, people are using their backyard decks for grilling, sunbathing and entertaining, day and night. Start by conducting an annual visual inspection of the entire deck. Listed below are 10 common defects that can cause a deck to fail. When inspecting your deck, pay particular attention to these 10 areas. Then, if you find anything suspicious, you can either fix it yourself or hire a professional carpenter. However, if you notice any serious structural problems, cordon off the deck and call a licensed engineer to evaluate the situation and offer a solution.

The end of each floor joist is fastened to the ledger, usually by a metal hanger. Most catastrophic deck collapses occur because the ledger is either badly decayed or not properly fastened to the house.

To prevent water from seeping behind and rotting the ledger, there should be a continuous length of metal flashing running along the ledger. The flashing must extend up behind the house siding and overlap the top edge of the ledger. If the ledger on your deck has no flashing, you must install one, which is a relatively easy job if the decking runs parallel to the house.

Simply pry up one or two rows of decking, install the flashing and replace the deck boards. It should be fastened with lag screws or, better yet, carriage bolts. Check to be sure the lags or bolts are fastened into solid house framing, not just plywood sheathing.

If your ledger is attached with just nails or decking screws, install half-inch-diameter lag screws or carriage bolts, spaced 16 to 24 inches apart. If the ledger is badly split or cracked, replace it. Most elevated decks have vertical wood posts that rest on top of concrete piers or extend down into concrete-filled holes.

You should also measure the diameter of the piers. To provide proper support, each one should be about three times wider than the post. Take a flashlight and peek beneath the deck to confirm that none of the supports has shifted out of position, cracked or sunk into the ground. If necessary, jack up the deck, install temporary bracing and then replace any damaged supports.

Elevated decks are typically supported by tall vertical wooden posts. Check the base of the post for water damage by poking around with an awl. If the awl sinks deep into the wood or the wood fibers are soft and spongy, then the post is rotting. If a post shows any signs of decay or damage, replace it immediately. All but the tiniest decks have large horizontal beams resting on top of the support posts or piers. The beams, in turn, support all the floor joists. Therefore, the structural integrity of the entire deck is dependent upon the condition of the beams.

Check the beams for large cracks and water damage. Confirm that the beams are securely fastened to the tops of the posts or piers. If the beams are made of untreated lumber, they must be at least 12 in.Building a deck can require a large monetary investment.

repairing deck footings

A properly constructed deck should provide years, if not decades, of useful service. They sometimes can require repair, and a common repair -- especially in northern climates -- is removing and replacing the concrete footings.

If improperly mixed and poured, concrete can become brittle and crack due to frost and ground movement.

Crumbling footings causes decks to sag and sink. Footings can be replaced to restore your deck to a level -- and safe -- condition. Place some scrap lumber under a floor jack, then cut a post that will fit between the floor jack and the beam of the deck.

Remove the nails that attach the existing post to the post base and jack up the deck until it is level. Put scrap lumber down under the base of the post jack, then extend the post jack until it is touching the bottom of the deck beam. Lower the floor jack until the post jack is supporting the weight of the deck. Remove the nails securing the existing post to the beam and take out the beam.

The weight of the deck at this location is now supported by the post jack. Break up the old footing with a jackhammer and remove the pieces from the hole by hand and with a post-hole digger. Keep breaking up the concrete a little at a time and remove the concrete until all of the concrete is out of the footing hole. Put the new sonotube into the footing hole. Mix new concrete in the proportions specified on the bag and pour it into the sonotube, filling it to the top.

Let the concrete cure for at least one day. Recheck that the deck is level, then measure from the post base to the bottom of the deck beam where the new post will attach. Level the deck with the floor jack if necessary.

Cut a new deck post to the length you measured in the previous step. Install the post in the post base with 10D joist hanger nails, then attach the top of the post to the beam with a new galvanized post-to-beam bracket using 10D joist hanger nails.

You may need to jack up the beam slightly to get the post in, then let it down.

Code Requirements for Decks

Measure the depth and width of the footing hole when you dig out the old concrete to ensure that it meets building codes. If not, dig out the hole until it meets code requirements. Do not let anyone on or around the deck while this repair is under way. The post jack is only in place as a temporary support until the new concrete can cure and the new post installed. Emrah Oruc.

The deck footing can help the deck to be in the perfect place, and you can also replace the deck footings when you come to replace the deck with a new style. Fitting your deck footings close to the frost line can also cause them to become damaged.

Repairing or restoring your deck footings will give your decking a new lease of life, and so long as you have a few basic home improvement skills, you should be able to manage this task quickly and easily. The first step is a hard task, as it requires you to dig holes around the deck footings. You will need to have a large spade and be prepared to do a lot of shoveling, but you will also need to brace the front of your deck, either using jacks or specialist bracing equipment.

The bracing should hold enough of the decking upright to support the entire deck when you expose the footings. Before you start digging, you should also supply yourself with guidelines on footer depth for your area, which will tell you how deep the frost line is in your particular area.

You will also need planning permission to repair the deck footings, as the job will need to be done to code before you can consider yourself finished. Once you have exposed the deck footings, you can then begin to check them over. Look for evidence that there has been splitting, or for signs that they have developed problems. You should check for insect damage too, as this will weaken the footings and make then more likely to fall. Your footings may be made of wood, in which case you will have to perform a very quick repair, or they may be made of concrete, which will be easily replaced.

Take some additional lumber, and fit this around your wooden footings. The lumber should be screwed into place, and a layer of caulk or concrete applied over the top. This will allow the lumber to bind tightly with the original footing. Apply a layer of water-resistant varnish before you install the lumber, in order to protect it better against frost and moisture.

If you have concrete footings or want a better footing for your deck, then you should mix together some concrete and pour it around the footings that are already in place. This concrete should then be layered with a line of gravel or crushed stone, which will make it stronger. Once you are finished, you can then leave the concrete to dry before adding the soil back into the hole.
