Similar to a poured concrete footing, a buried post footing will also require a hole to be dug below the frost line. But getting to the backyard can be tricky.īuried Post Footing Buried Post Deck Footings So expect most professionals to charge between $200 to $400 a footing.Ī specialized deck builder will often use a power auger attached to a skid steer (Bobcat), making the job much easier.

Putting material for a 4′ (1.2m) footing at just under $60.īut then we have the labour to dig the hole. Add $10 for the post saddle to anchor the post to the concrete a lift it out of any water that pools on the concrete. Material is roughly $12 a foot for sono (cardboard) tube plus bags of premixed concrete. The biggest cost here is labour, with the material cost being little compared to the time it will take to dig the hole and mix the concrete. It is attached to the column above with rebar. This wide footing sits below the frost line and supports the entire structure. ![]() If you are building a deck on extremely soft soil or your deck is extremely heavy, you may need to create a wider footing at the base of your concrete pillar. But most require a minimum of 10″ (250mm) concrete column. Ranging from 8″ (200mm) diameter column to 24″ x24″ (600mm x 600mm) concrete pad and column. Most local building also dictate how big the concrete column needs to be. Installing poured concrete footings is already an intensive process that becomes more labour-intensive as there is an increase in the depth to which the footings need to be poured. The deeper the frost line, the more labour-intensive the process of installing poured concrete footings becomes. In Canada the required depth for deck footings varies from 18″ to 96″ (0.48-2.44m) depending on the region. While the frost line is usually around 40″ deep, it can be as deep as 70″ in some regions of the US.
