This tutorial will guide you through the process digging the deck post holes and then mixing and pouring the concrete. Before the concrete completely sets, you will then position the precast concrete piers.
You should have a fairly comprehensive list of materials for this project. If you have a pickup truck you can begin hauling the materials, otherwise, most home improvement centers will deliver. Be sure to inquire about delivery charges, if your order is large enough, the delivery may be free.
Skill Level & Time
Time to complete this project depends on the size of the deck and the level of help available, the times listed here are for two people on a 10’x 30’ deck with the house defining two sides of the deck.
• Beginner - 7 to 9 hours
• Intermediate - 6 to 8 hours
• Advanced - 5 to 7 hours
Check your layout from the Marking & Layout tutorial. Check the string lines one more time to make sure they are in the right place.
Follow the mixing ratios of dry concrete mix and water, the final strength will be reduced if the ratios are off.
Order more concrete than you need, it is easier to have extra than go back for more.
Watch the weather, if it is going to rain or be below freezing, consider letting the sky clear and the ground warm up before pouring concrete.
If you have more than a cubic yard of concrete to pour (27 cubic feet), consider getting a concrete buggy. If you have two or three cubic yards, consider a concrete truck, as the cost can easily be balanced by the convenience. Note, concrete usually comes bagged in 60 and 90 pound bags, a 60 pound bag equals 1/3 cubic foot, and a 90 pound bag is 1/2 cubic foot.
