Building A Floating Deck With Concrete Blocks

Using a mason s string level add or remove soil beneath the blocks until they are level from end to end.

Building a floating deck with concrete blocks.

If desired add one or more blocks in the center of the rectangle. Cap blocks on paver base will support the step section. It s a floating deck which means it simply rests on blocks at ground level and is not anchored deeply in the ground. Deck blocks are simple to use deck blocks level the places where the block will be placed.

While you can build one on concrete pavers or over an existing level patio perhaps the soundest way to support a floating deck is with pre made concrete deck blocks that have notched tops designed. The 2 inch by 6 inch joists will rest on top of the blocks. The required depth of your footing is determined by your local code. Floating deck plan and layout the plan for this deck is to use paver base and concrete deck blocks for the foundation.

The blocks should be spaced to make a 7 x 19 rectangle leaving about 6 inches from each block for deck boards to add another 8 x 20 rectangle. Arrange four concrete blocks in a rectangle so they are 12 feet apart along the long sides of the rectangle and 10 feet apart along the shorts sides measuring from the centers of the blocks. Be sure to pack the earth before replacing the block after each adjustment. The columns should measure 11 feet 10 1 2 inches from the center of the first pier to the center of the last pier with the piers.

Lay out the concrete pier blocks into six columns and three rows. This type of deck can only be made in areas that do not have a deep winter frost. If you are connecting the deck to the house you will more than likely need to pour concrete footings that will extend beyond the frost line to prevent the deck from heaving up with a frost.
