Just finished up my weekend installing a 4' high galvanized chain link fence. I was able to install all of the posts and finished installing some of the top rails. Post holes were 6 inches in diameter and had a depth of 2 feet. I used 5000 PSI Quikrete Concrete mix that I mixed before adding it to the post hole. How long should I wait before I install the chain link mesh and tension it? Compressive strength, ASTM C39 1 day 1500 psi (10.3 MPa) 3 day 2500 psi (17.2 MPa) 7 days 3500 psi (24.1 MPa) 28 days 5000 psi (34.5 MPa) |

I just built a running yard for my dogs with 4" treated posts. 6ft high 2x4 welded wire fence and the posts are 2ft down. I used the same concrete mix and I put the fencing up 24-36 hours later. But with this fencing, I don't have to have it super tight. Someone's going to tell me I did it wrong for not using crushed rock/gravel at the bottom of the post holes. The previous running yard just had untreated landscape timbers as posts and they lasted nearly 30 years  |

How was the previous fence done? If you put the bottom of the posts in concrete you made a swimming pool to make sure the wood stays wet for prolonged periods. While immersed wood (like pilings in water below the surface) lasts very well wood with repeated non-saturation and then drying fails. |

He used untreated landscaping timbers. Initially 2 ft underground in concrete. I had a "fun" time digging it all out for the new fence as the wire had sunk about a foot under ground, along with the posts and concrete. The very bottom of the posts are not encased in concrete. Just in the dirt. |

Just in the dirt. The few inches of gravel is just to ensure the bottom of the post is not encased. I usually set therm in, plumb them, add a few inches of pea gravel, then concrete. Try to bevel the concrete at the top away from the post to shed water. |
