Do deck posts need to be anchored?

Posts must rest on and be secured to concrete footings in order to appropriately resist varied degrees of weight. It is vital to remember that patios and pre-cast concrete piers do not qualify as appropriate deck footings. They may provide some support when loaded with equipment or furniture, but this type of loading does not give the post enough security to withstand the force of an earthquake or severe windstorm.

The best way to ensure proper resistance to earthquake and wind forces is to embed the posts at least 3 inches deep into a stable base of compacted gravel or soil. The posts should be securely tied to their footings, preferably by steel anchors embedded several more inches into the ground.

If you want your patio to be truly safe, you should reinforce it with ties to other parts of the house or install anchoring devices such as anchor bolts on exterior walls. This will prevent the posts from pulling out under heavy loadsa nd will make sure that they can withstand even the strongest winds.

The alternative to embedding posts into the ground is to use cement-based footings. These can be poured over an open trench or placed directly onto the floor of a building project and allowed to set up before any wood is placed on top. This method is very efficient because it uses less material than solid blocks and has a smooth surface ready to lay tile or stone on.

Why should deck posts not be set in concrete?

A deck post should always be put on top of the footing rather than inside the concrete, since this might cause it to break. The photo on the left shows a post fixed to the top of a footer in a bracket. When concrete is poured around a deck post in this manner, moisture in the soil causes the post to decay. This can lead to stress on the foundation wall and sometimes results in its failure.

The photo on the right shows how a post would be cast into the bottom of the footing. Here, too, there's a risk that the post will decay and have to be replaced. It's important to use pressure-treated wood for your deck posts because the chemicals used to treat the wood prevent any further decay. If you choose another type of post, such as aluminum or steel, then you will need to apply some kind of protective coating to it regularly. These days, many homeowners choose to have their deck posts coated with polyurethane instead of using pressure-treated lumber. This is because it looks good and doesn't require any maintenance other than cleaning off any dirt or debris that may collect around them.

Setting posts in concrete is the most common method for creating a stable base for a patio or deck. However, this isn't the only way possible; others may be able to provide more stability at less cost. For example, if you choose to use aluminum posts, you may want to invest in an aluminum railing that's designed to support its own weight.

Can I set deck posts without concrete?

Plastic piers necessitate digging, but unlike footings, no concrete is required. The pier is inserted into the hole and fastened to the post, providing you with your deck without the need to spend hours creating footings. These are easy to install and remove for any major renovations or repairs. They also cost less than footings.

The best option for shallow foundations is to use concrete piers. If you choose this option, make sure the ground is stable before you start building your deck. Piers should be at least 2 inches in diameter and deep enough to reach solid ground. Concrete is then poured around the pier to hold it up above ground level.

If you do not want to use concrete, metal pilings work well as long as the soil is not very wet. Dig a hole large enough to fit the piling, and then drop it in. It should be deep enough so that its top is at least 2 inches below ground level and contact with the tree root system should be avoided. You can then attach the deck to the piling by using screws or bolts. This is an inexpensive option that does not require time or effort from you. However, these may have to be replaced periodically due to corrosion.

Deck posts are available in a wide variety of sizes and types.
