How deep do you have to go down for a 6ft. fence?

Question

am putting up a privacy fence in my backyard- how deep do I need to go down for a six foot fence? do I have to cement in the 4x4's?

Answer 1

The 4x4 posts are typically 8 foot to allow you to bury 2 feet. Under normal circumstances you do not need to use concrete. BTW cement is the wrong term, concrete is the right term.

If the ground is very loose, like sand, you will need to go in further. Part of the strength is in the layout of the fence. If you have a right angle on it, it will make it much stronger. That goes into most designs well.

Answer 2

We have elk at home the post for that fence are 12 feet long and the are put in the ground 4 feet deep so its 8 feet overall. Little diffrent fence but strong and sturdy. 1/3 of the post is in the ground. A 6 foot fence 1/3 is 2 feet. Your not putting elk in there but if its windy where you live a lot of the fence strength comes from the ground. If you tamp your post in with a 2x4 or something they should stand up pretty nice and hold up well as well. Up here in minnesota we have to use treated lumber for ground contact and a stonger treated lumber for concrete contact. Just something to keep in mind. Treated lumber will hold up better underground.

What a cute combo bulldog and a husky:) I use to own a siberian husky, and he could jump a fence of 4 ft high from the ground at 2 yrs of age. And im sure u know by now that they love to dig many deep holes in the ground. And english bulldogs u should have no problem with them with the fencing, your husky is the main issue. U have the right idea about the fencing, but id do a 6 ft above ground chain length fence and 1 ft underground w/ 4 ft chicken wire above ground attached to the chain length fence, im sorry but im not sure of what kinds of chicken wire are made, just be sure the holes are small though. And if u like to try it, ive heard u can put a big sandbox in your yard to prevent lots of or more holes being dug in your yard! Good luck:)

Answer 4

if you are putting up a solid fence go down 1/2 the height. so in your case 9' posts. that covers you if the fence is in the open and wind could blow it over. if an open style fence, 1/3 of the height. as far as the base goes, use gravel. it provides drainage so the posts won't rot out. put down a 6" base before you drop the post in then fill around the post with more gravel. when the post is level and in position pack the gravel down with a 2x4 and a sledge hammer, adding more gravel until the hole is full. good fences make it so you don't have to see 'that' neighbor, right? good luck and have a happy!

Answer 5

You will have to have them 3 ft below grad (ground level) + 6ft fence height = 9 ft
Yes you will have to anchor them in concrete. A 4X4 post ( green treated or ceder ) your hole will have to be at least 8 inches around.

Answer 6

i'VE INSTALLED A 6' FENCE USING 9' 4 X 4'S SUNK 3' DEEP IN SANDY SOIL. Both the posts and fence material was 'pressure treated' meaning it was heavy wood. You can pour dry cement mix into the holes and the water content of the soil will harden the the mix.

Answer 7

I would call a fencing company and ask them for the correct footage. Or, you could call Home Depot or a similar store and ask someone in the fence department.

Answer 8

You should dig down an additional two feet for each posthole, therefore you'll be using 8 ft. 4x4's; you only REALLY need to cement your corner posts, but it doesn't hurt to do them all.

Answer 9

It is better if you cement the 4x4 in a 1 foot hole if you don't cement dig at least 2 feet.

Answer 10

go at lease 4 or 6 feet and put in to a cenment bucket to save it from going loose in the future.
