![]() The vertical concrete pier form might be one you made, or you’d purchase thick round cardboard forms that you cut to the height needed using a hand saw. Once the footing was smooth and level, you would install two extra pieces of vertical rebar steel to allow you to make a mechanical connection between the vertical concrete pier that you would install the next day. You’d also have to stop occasionally to carefully place short pieces of horizontal reinforcing steel and then add the rest of the concrete. Finishing would find you laying on your belly and reaching down into the hole to get this concrete smooth and level. You’d first have to dig the hole for the pier, usually 24 inches in diameter, then pour a concrete footing. It used to be that this required a multi-step process fraught with frustration. You’d probably be better off to consider using poured concrete piers that you construct on your job site. Don’t forget, the normal deck block has no way to mechanically attach to the wood deck posts other than friction. There are very few places in the USA that have this climate. Precast deck blocks are probably best suited for climates where the frost penetrates into the soil no more than 4 or 5 inches in the winter. Precast Deck Blocks vs Poured Concrete Footings or Piers All concrete used to support decks should have reinforcing steel. Concrete only has one-tenth the strength in tension as it does in compression.
