building a low profile frame is necessary. you will need to use a flush beam which is set at the same level as the joists as opposed to a cantilever beam. if the bottom of your deck frame is less than 6' above the ground or partially buried you should use pressure treated wood that is rated for ground contact.
establish the highest and lowest points with a string and string level to get a rough idea of how deep to dig and how much gravel to put in to make the ground level deck footings blocks level figure a . tamp the dirt with a block to make a firm base, then spread the gravel.
where you may think twice about building an elevated deck with shallow footings, the safety risk from the frost-heaving that shallow footings may experience on a grade-level deck is very low. the main code provision for footings that applies to freestanding decks r403.1.4 calls for a minimum footing depth of 12 inches below undisturbed ground surface.
start with a plan. you can follow our platform deck plans or create your own. here are some things to keep in mind when building a ground level deck: a platform deck can be any shape, but basic rectangles are easiest. the fireplace notch in the corner of our deck made the whole structure a bit more complicated.
low profile deck footings for low level deck. by john stuart victoria, bc, canada i am building a low profile deck, have couple of questions about footings to keep the deck low to the grade. the deck is pressure treated 10'x20'. the substructure is 3 2x8 beams with joists mounted flush with top of beams to save height.
show how to fasten the stair frame to the deck frame. install blocking to firm up the edge of the deck and support posts for railings and benches. use a custom jig to position bench posts accurately. install blocking and furring to support skirt boards that will surround the deck.
this video includes a material list and step-by-step tutorial on how to build a deck. dig holes for piers, fill with concrete and let it set up. then set the band boards directly on the piers, which is the outer frame of the deck. next you'll install the floor joists and joist hangers. nail in the sattles, then lay down decking.
step 2. dig 8-inch-diameter holes to the frost depth in your region at each center point. with the holes dug, mix enough concrete to fill the five holes -- one in each corner and one in the middle of the deck. make the tops of the footings even with the ground at each hole project diagram, ding 2 .
then i proceeded to build out from there, attaching the ac2 pressure treated 2 x 8 joists on 16-inch centers with three 4-inch screws, and making sure everything stayed level across the entire framework of the deck.
low level decks do not require deep footings. you can use bolt on post shoes where appropriate and if you are going in ground you can use stumps into concrete footings which are very easy to set ground-hugging decks do not require as much support for joists and so the frame design and structure may be simplified, saving on materials, labour and time.
build a floating deck step 1: tools. you don't need a shop full of tools to build a deck. step 2: foundation blocks layout. the main area of my deck is just a little bigger step 3: set blocks. the area where i was laying out the blocks was mostly level, which was nice. step 4: build frame. the
