How low can a deck be to 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 I build a deck without digging holes?

Yes. It’s possible to build a deck without digging holes. This type of deck is called a floating deck, and it sits right on top of the ground without any posts or support areas that you’d dig down into the ground [to secure].

How do you support a deck without posts?

Instead of using footings, adding a level of gravel will give you the drainage aspect you are looking for. You can then add a frame of wood that anchors in concrete blocks that sit in the gravel, creating your new deck. Concrete blocks won’t rot, making them an ideal option for those who don’t want to use wood.

Will 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. Especially in loose soils or wet conditions which requires more weight distribution.

Can you put decking straight onto grass?

If you’re laying your deck straight onto the ground, cover the area with a layer of weed control fabric. Then add 40 mm to 50 mm of gravel on top. Lay the decking on the grass in your decided design and leave the right expansion gaps between boards (5 to 8 mm along the length of timber boards, and 3 mm along the ends).

Do I need to remove grass before decking?

If your decking hasn’t been laid yet, remove or kill the grass in the area that it will go on. By doing so, weeds are less likely to become established and spread. Also, you’re less likely to have grass growing through your decking.

What is a floating deck?

A floating deck is a deck that isn’t attached to a building and they “float” above the ground. Generally, floating decks are low to the ground and don’t require handrails or even staircases. They are sometimes called “grade-level” or “freestanding” decks because they’re built just above the ground level, or grade.

Should a deck be level or sloped?

What slope should a deck have? The answer is it depends if the deck is solid or not. A solid deck needs to be sloped between a 1/8″ (3mm) and ¼” (6mm) per foot to encourage water drainage. Decks with properly gapped decking boards require no slope as rain will naturally run off the boards even when level.
