but i've seen as late as yesterday a builder placing the post in about a foot of concrete in the footer hole and then filling the remainder up with dirt. i've checked code in our area and while it doesn't recommend it, it does allow the posts to be buried as long as there's at least an 8' concrete base.
getting ready to build a deck digging the holes. still cant make up my mind between using concrete piers or burying the 4×4 posts 42 down. it will be a free standing deck about 35 off the ground approx 16x37 .
deck posts buried posts or concrete? dpbellus posted in construction techniques on may 9, 2009 10:12am i posted a question yesterday as to the best way to dig post holes for a deck i am building.
deck post attachment methods need to be accessible for installation and inspection. 3. pt wood rated for ground contact below grade can easily become immersed in water and prematurely fail below grade without means for visual inspection. this material at best is good for only 15 years. 4. the closest code details for wood foundation walls built
ground level is where rot takes place .on most posts. you can also coat the posts to above ground level. those brackets are little more than vertical compression stand-offs. i don't do gravel in the holes. putting a bit of crete in the bottom first and then you're good to go. then let's go waste some time talking about expanding epoxy post sets
re: deck posts: buried or on top of footing? allan, way it was explained to me is that with frost heave it will eventually loosen the connections at the house and deck location and could also loosen at the deck and stair connection. how long or how much it heaves is an unknown as far as i know but i have seen things like tom describes.
submitted 3 years ago by rbevans. i think we all know the 'deck post' and all probably cringe a little when a deck post is made. i'm looking to redo my deck and unsure if doing a buried post and footing similar to this deck and back fill with concrete once squared is acceptable or if tubing is recommended way.
one way is to pour concrete in the post hole, set the post on the concrete and backfill with gravel. to help prevent rotting, this deck will have wooden posts attached to concrete footers above ground.
1. an 8 thick by 12 diameter concrete base poured in the bottom of the hole. the post resting on top of the concrete and the rest of the hole backfilled with soil. with this idea id have about 30 of the post buried in the soil. this seems cheap and fairly easy, but the post would be in contact with soil. 2.
we have an entire hillside of buried posts of all types of lumber in concrete, out, different ph's and put under different conditions. the answer is simple and factual: keep the base of the post
just a note, this is for support posts only not fence posts. fence posts have pressure from the side and so need to be buried. i believe that fence posts should not be set in concrete either but instead set in compacted gravel.
you can protect cedar posts by soaking the ends in a bucket filled with copper napthenate jasco, copper green wood preservative and others . it takes time for the chemical to fully penetrate, but
the correct depth can be determined by checking with your local building code department or online resource. in warmer climates you may be able to use 10 posts, which would be buried 2 in the ground, and colder climates will most likely use 12 posts which would be buried 3-4 in the ground.
can deck posts be buried? yes, if they are rated for ground contact. this is dependant on local codes. some do not allow the burial of posts under any circumstances and they must be set on or physically attached to concrete footings. should i install a pressure treated wood deck with the boards 'bark up' or 'bark down'?
re: deck posts: buried or on top of footing? i see quite a bit of cedar used for stair treads and have seen a few time it being used for the framing. when i have seen it is on floor that you are going to see the entire frame of the deck. as in a 2nd floor deck with a seating area underneath it. and it all gets stained to look nice.
the advantage to burying your posts is little to no lateral bracing is needed and it is less work over all. the advantage of concrete piers is longevity and easier maintenance. it's a lot easier to replace a post that is not buried.
the buried post footing. the pressure treatment companies insist that these posts will last longer in the ground than the deck frame that is built above it and this practice is accepted by the irc code. the buried post method offers the advantage of reducing the amount of concrete work required for each footing and actually provides additional
for comparison, the rost line in kansas is 36 inches. in minnesota it can be over 5 feet. for a 10'x20' deck with posts along the perimeter, using 2x8 joists you should do 3 rows of posts each way.
plans call for the posts to be embedded in concrete, but it seems like when theyre installed this way in our area ontario, canada , they always rot just below grade. while this makes removing the old posts easythey just snap off at their baseid prefer that they last longer.
posts are notched and are supporting the rim joists, attached with nails; there are no other supporting posts or beams; deck extends about 8 feet out from the house; deck is about 4 feet off the ground for one section, and 2 feet off the ground for the other section; deck is located in texas, so snow is not a concern
should deck posts be buried in the ground? in my opinion, its not a great idea to bury the deck posts in the soil even if theyre resting on concrete piers. ive seen lumber thats treated for ground contact succumb to rot and insect infestation.
should deck posts sunk in concrete or above ground? what is a better way to go. i have to fix a friends 8x8 porch that is about has moved about two inches from the house. the 4'x4' posts supporting it are on a square slab of concrete maybe a foot deep into the ground. but on a buried concrete footing and then fill around the post
