Concrete footings will support greater loads than deck blocks due to the increased mass and wider bearing area. On the other hand, the cost of in-situ concrete and the associated cost of soil excavation makes concrete footing the more expensive option. Deck blocks are fairly cheap and do not require much labor to install.

This article will hopefully help educate you and explain how to build a shed foundation with deck blocks.

There a few different types of foundations, some will be referenced and described. How To Build A Shed Foundation With Deck BlocksĪ foundation is the most important aspect of your project since the whole project rests on it. This is one place in which too many is much better than too few. For a smaller shed that wont be stuffed with heavy motorized gadgets, you can go to a support every four to six feet. The average 12 x 12 shed, for instance, will use at least 18 blocks. That lawn tractor is heavy, and even a few cans of paint can add a surprising amount of weight.Ī good rule of thumb is to use one block support every three to four feet for a shed that will see normal use. Youre not done, though, because you still have to guess how much weight will eventually go into the shed. Its hard to know how much your shed will weigh, although if you buy a pre-built shed, you may be able to find out from the manufacturer. That may sound like a lot, but its tough to calculate how many you will need from that figure. what do you expert suggest? Thanks in advance.Solving Several Problems at Once – Titan Deck FootĪ single 12×12-inch deck block can hold up to 2,000 lbs. I was wondering instead of pouring new concrete - is it okay - if I clear the dirt off the existing footing and use concrete blocks (available in big box stores) directly on footing and cut post to rest directly on the blocks? Wouldn't it transfer all load to the existing footer in this manner? The height and the way the posts are located - seems like lateral loading may not be issue here. This seems like a major lift - essentially may have to remove all joists to access each post (6 posts total on 30 feet ). I may have to remove at least 3-4 joists (joists are at 12' OC and in some part 8-9 inches) around each posts. I know the proper way to fix this is to use tube and pour concrete on top of the existing footing (and attach using rebar) - but because how the beam and posts are located - there isn't much space available to do this. The beam that runs across the deck - which supports joists from ledger board to the end opposite of it - is about 8 feet from ledger board and 5-6 feet from the end of the deck. Deck is pretty low - beam is 16 inches from ground. I'm planning to replace deck boards with composite and during that process I found this issue. Even with this, deck is surprisingly stable and other parts of the deck framing is in very good condition. Deck posts are 6X6 treated wood and resting on cement footing - but cement footing is below ground surface (may be around 6-8 inches) and because of that many posts are rotting. Its connected to ledger board on the side of the house.

My 30x14 deck is almost 20 years old (located in Philadelphia suburbs).
