How do you make concrete fence posts?
In terms of the ratio to use for a concreting fence posts, the best mix is a mix of 1:2:4 (1 cement, 2 sand, 4 aggregate). Concrete is always best mixed using a cement mixer to ensure it’s even, but if you only need to mix a little, hand mixing is ok (see mixing concrete project above for tips on how to do this).
How deep should a concrete fence post be?
The width of the post hole should be 3 times the width of diameter of the post. For example, if you are erecting a 6 foot high fence using 4 inch fence posts, the posts need to be 6 feet above the ground. 6 divided by 3 is 2, therefore the depth of the hole required is 2 feet.
What concrete should I use for fence posts?
Fast-setting concrete is ideal for installing fence posts since it doesn’t need to be mixed in a bucket or a wheelbarrow. Once you’ve finished digging your post holes, add about three to four inches of gravel into the bottom and compact it using a post or a 2×4.
Should I use concrete or cement for fence posts?
Concrete is the most secure material for setting fence posts, especially if you have sandy soil. Gravel may be okay with dense, clay-heavy soil, but in looser soil, concrete is the only thing that will truly keep your fence posts stuck in place.
What’s the difference between Postcrete and concrete?
Concrete takes several hours or a day or two to set. Postcrete sets in a few minutes, several tens of seconds, even, so you don’t have to support the post for nearly as long as you do with concrete.
How do you keep fence posts from rotting in concrete?
Caulk Around the Fence Post Base Apply high-quality exterior acrylic latex caulk, or silicone specifically designed to adhere to concrete, at the base of the post.
Is 2 feet deep enough for fence posts?
Dig post hole so diameter of the hole is 3 times the width of the post (i.e., the hole for a 4” wood post should be about 12 inches wide). The depth of the hole should be 1/3-1/ 2 the post height above ground (i.e., a 6-foot tall fence would require a hole depth of at least 2 feet ).
How many bags of Postcrete do you need per post?
You’ll need to bury the posts at least 2ft In the ground. As for how many bags of postcrete you need per post, that’s purely dependant on how big you make the post holes. As a rule of thumb, when using standard post hole diggers, I average 1 bag per post. For larger holes I would allow 1.5 bags to 2 bags per hole.
How much concrete do I need for a post hole?
Remember, the depth of the post hole should be one-half of the above-ground post height. (Example: For a 6 feet above ground post, use a post with an overall height of 9 feet and place 3 feet in the ground). The calculator will indicate the number of 50 lb. bags of QUIKRETE® Fast-Setting Concrete you need.
Will concrete rot fence posts?
A: Actually, your point is well taken. Simply setting the posts in concrete does create a condition that will accelerate rot in the bottom of the posts. With pressure-treated posts, the rot will be slow. The concrete at the top should be sloped away from the post to grade level to avoid water pooling around the base.
Do you need gravel under concrete?
Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.
How many bags of concrete do I need for a 10×20 slab?
A 60-pound bag yields. 017 cubic yards, and an 80-pound bag yields. 022 cubic yards. For a 10 x 10 slab, you would need 77 60-pound bags or 60 80-pound bags.
Does filling a post with concrete make it stronger?
Filling with concrete is not as effective as increasing wall thickness or changing the shape, but it’s a proven technique.
How long will wooden posts last in concrete?
