Anchor Posts For A Wood Fence

Anchor Posts for a Wood Fence


Anchoring fence posts in the ground can be accomplished in two ways--by cementing or anchoring. Both methods require planning to make sure your posts are plumb and at the right angle in relation to other posts. Post anchoring in cement can save you a lot of money if you have a lot of posts to install, and cementing also tends to be a bit more secure. Does this Spark an idea?


Instructions


Cement Method


1. Make sure wood posts are either redwood or cedar.


Map out with wood stakes and construction string where all the posts are going. This allows you to plan for how much material you will need and also check the angles and lines.


2. Dig a 2-foot post hole with a post-hole digger or power auger. Insert the 4x4 red wood or cedar post into the hole. The post should be 25% taller than the size of the fence. For example, if you are building a 6-foot fence, your post needs to be 8 feet long to allow for 2 feet to be buried.


3. Fence post evenly spaced and in a nice line.


Throw crushed gravel into the hole with a round nose shovel until it fills the bottom 6 inches. This will help water drain away from the post.


4. A good wheelbarrow should suffice for a 2-foot deep hole.


Place one shovel full of Portland cement, two shovels of sand and three shovels of aggregate in the wheelbarrow and repeat until the wheelbarrow is full. Mix with the hoe, then add 5 gallons of water until you have a slurry solution of cement. The cement should be on the wet side so it will pour easily.


5. Brace your new fence post with 2x4s.


Pour the cement in the hole, around the post. Use a level to check that the post is plumb and level, then brace it with scrap 2x4 or rope and wood stakes. The cement will dry completely in one week, but can be worked on after it sets. Follow the directions on the bag.

7. Map out with wood stakes and construction string where all the posts are going. This allows you to plan for how much material you will need and also check the angles and lines.


8. Hammer post anchors into the ground with a sledgehammer. Place a 2x4 over the hardware so the sledgehammer does not cause damage. Use a 30-inch post anchor spike for a 6-foot post.


9. Insert a post into the anchor and secure the post by screwing in 2-inch wood screws with the power drill.
