When should you deck a block?
If the block is NOT square it’s a no brainer, gotta deck it. If it is square and it passes a flat test using a straight edge and a feeler gauge there is no “normal” reason to deck it at all. If you want to get fancy and go for zero deck height (not a bad thing) or some other “race ready” reason, then deck it.
How high off the ground should a deck be?
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.
