Deck supplies
We ordered all our deck material from Morrisburg Building Centre and had it delivered on April 7. That weekend we went ahead and officially started building by starting with the concrete deck footings and sonotubes.
1. Dig the holes
Depending on your type of soil, there are several different options for digging your holes. You can use a post hole auger, which is probably the easiest if you have sandy soil. Our soil has a lot of rocks in it and the post hole auger wouldn’t have worked very well.
2. Frame the footings
On Saturday we built 2′ x 2′ frames for the footings using 2″ x 6″ pressure treated lumber. The holes had to be a little over 4 feet deep to make sure that no frost could get under the footings. We had to place the footings exactly centred where the 6 deck posts would go, and make sure they were perfectly level.
3. Pour the footings and add rebar
We also ordered the portland cement from Morrisburg Building Centre, and a load of gravel delivered for the concrete. Doing a big project likes this during a pandemic can make tool rental a little more difficult. Instead of renting a concrete mixer for this project, we were able to find a used mixed that we bought.
4. Pour the sonotubes
The next day once the footings were mostly dry, we put the cardboard sonotubes over the rebar, centred them in the footings and under the string lines, and made sure they were level. Then we also braced them in both directions using 2″ x 4″s. Then we mixed up the concrete and shoveled it into the sonotubes.
5. Backfill the sonotubes
After letting the concrete cure for about a day, Tony backfilled them using the mini excavator.

Why are sonotubes used?

Traditionally, that process was very labor-intensive and required the installation of specialized molds. These molds then had to be removed when the column dried, which further slowed down the construction process.

Once you have allowed your concrete column to dry fully (which may take more than 24 hours), you can begin the process of removing the cardboard tube. This is typically done using an electric saw, which should be well balanced to prevent the blade from contacting the concrete.

Once you’ve fully filled your Sonotube, you’ll want to even off its cap. This can be done with any piece of flat, level material, such as a piece of cardboard or wood. You can even use your hand, so long as you wash off excess concrete from said hand immediately.
