How do you prepare the ground under a deck?
To suppress the growth of unwanted vegetation underneath the deck, the area should be covered with landscaping fabric. First, add a layer of coarse sand for drainage. Then cover the sand with landscaping fabric. Bury the fabric under several inches of gravel.
How far down do you dig for deck posts?
Dig the holes six inches deeper than the required frost line depth for your area, and slightly wider than the concrete footer tubes you’ll be using.
Do deck blocks sink?
The deck blocks can sink if the soil under them erodes for some reason or the weight is unevenly distributed. That’s why it’s a good idea to use more than less.
Can I use 2×6 for deck joists?

How many footings do I need for a 12×16 deck?
four footingsA standard deck will need four footings parallel to the house, but they will need to be temporarily braced by 6 inch-by-6 inch posts.

How high should a deck be off the ground?
There is no standard height for a “grade-level” deck—the maximum measurement from grade to the deck surface could be 6 inches, 12 inches, 24 inches, or more. But generally speaking, I apply the term to decks that are up to 30 inches above grade, since guardrails are required for any decks that are higher than that.
Can pressure treated wood sit on the ground?
Pressure-treated wood is softwood lumber, typically southern yellow pine, that’s been chemically treated to resist rot, decay and termites. Lumber treated to “Ground Contact” has a high chemical retention level and can be placed directly on or in the ground with better protection against rot or decay.
Why deck posts should not be set in concrete?
