12" footings from Lowes???

I designed and purchased my deck from Lowes. On the spec sheet they have
12" post hole footings for the 4x6, but no concrete added.....are these pre-cast footings? Thanks!

My guess is that Lowes sells the same tubes as Home Depot. You need to fill them with concrete.

Since it comes from a big box store, the "footings" could be the 12" wide pyramid concrete "footings/pads" that are not accepted by most codes. - Not anywhere close to a proper Sonotube installation.

More details on the proposal from Lowes is necessary. If the soil is really bad 12" Sonotubes may not be enough.

I spoke with lowes, they said to just drop the footer in and backfill with dirt. No concrete needed as it will rot away.

They said all I need to do is dig the hole, place the 12" footer in with the post and backfill with dirt. So moisture won't get in and rot the 4x4.

Yep....odds are they are talking about Dekblocks or something similar. Need to talk to your inspectors office and find out if they are approved and what else might be needed.

Take a look here...bout 2/3 of the way down. Take note of the uplift protection requirements mentioned. http://www.deckmagazine.com/article/84.html

An air-borne deck is not a pretty site and can be very dangerous. A 50# "dek block" does not hold down much, especially when the deck is just sitting on it and is not attached to anything. If that is what it is, it is just a cheap DIY item and not something anyone qualified would use.

People with vests in a big box cannot be trusted with any advice, but they might even try to give advice on a medical prescription if they thought they were qualified. They will try to sell anything.

Pole buildings are pretty much built this way, however they are self standing structures.

IF the deck is not attached to a building you are fine with not digging footings. My Father and I built two decks next to his mobile home that was not attached and is free standing on cast piers. The frost will move the deck about 4-6" up in the fall and then back down in the spring. It has stayed level for the past 10 years.

If it is attached to the house you will need to dig and pour footings.
