HOW TO INSTALL A McGREGOR DEER FENCE: MORE ABOUT CEMENT FOOTINGS
EARLY STEPS, CONTINUED
Cement Footings, continued
Plan on using a high-strength concrete mix (cement mixed with crushed rock) that should be available locally in 60 or 80 pound bags. Do not use the quick-setting type unless that is the only kind available. Mix cement and water to create a batch of cement with a jelly-like consistency. Use this soupy mixture to fill the hole to a few inches above the rocks if the hole is 3 feet deep, or to a depth of a few inches if the hole is 2 feet deep.
Then return the pipe to the hole and use moderate-size rocks to secure it firmly in place until it can stand on its own, keeping the post as close as possible to the center of the hole. Take a carpenter’s level and place it against the side of the post to make sure the post is straight up and down; adjust as necessary until the post is vertical. Then fill the hole to the top with the cement mixture and take another level measure to ensure that the post has not shifted. Let the cement set for 12-24 hours if the temperature is above 60º F, or for 24-48 hours if the temperature is below 60º F (it is not advisable to do this work if the temperature is below freezing).
