Install steel fence posts with a few tools and steps to ensure your fence lasts long and stays. Mix the cement and pour it into the remaining area in the holes.
Set the post into the hole and attach 2×4 braces to adjacent sides of the post. Use a level to position the post perfectly vertical. Fill the hole with Fast-Setting Concrete up to 3 to 4 inches below ground level. Pour about a gallon of water per 50 lb bag into the hole and allow the water to saturate the concrete mix.
If you decide to install your chain link fence without concrete, use a post-hole digger to make a hole deep enough to bury the posts at least two feet, or about 1/3rd of the height. Never pound the posts into the ground, especially if you have hard clay or rocky soil, because you'll bend the tops.
Dig the holes the same way as you would to set posts in concrete. When setting fence posts in gravel, you should bury at least one-third of the fence post. Use crushed gravel to set the posts. Pour 5 in.
