Step 1: Place the two corner Dek-Block® piers

Deckman's Comments

There is no such thing as a perfectly level yard. I get a lot of calls and e-mails from people who try not to use 4x4 posts. The best tip I can give anyone building a shed floor is to use 4x4 posts, even if you only have a very slight slope of the yard. Leveling every block to each other is very difficult and time consuming. If you need a 2-1/4" 4x4 post, cut a 2-1/4" 4x4 post. It takes about 90 seconds to measure and cut a 4x4 post, and the post only weighs a few pounds. Moving a block up or down to an exact measurement takes 4 to 10 minutes per block. Remember, these are 42 lb. blocks you're working with. Save your back for carrying the cooler onto the deck when you're done.

Don't spend a lot of time leveling the Deck-Block® piers. The block does not need to be perfect. The block can be leveled with only your eye. Position the block so that it looks level. If you place a level in the block, you are spending too much time. Any slight difference will be made up with the 4"x4" post. You also want to make sure the Dek-Block® piers are sitting FLAT. You don't want any rocking of the piers on the ground.
