Set Posts in Concrete to Repair a Damaged Mailbox
According to the United States Postal Service, there are about 52 million curbside mailboxes in the U.S. Unfortunately, many of these mailboxes are often damaged by inclement weather, reckless driving or other unexpected incidents that ultimately inhibit the successful delivery of mail. While it’s unrealistic to think that all harmful accidents to mailboxes can be prevented, homeowners can minimize the time a damaged mailbox is out of commission if they set posts in concrete.
There are many fun and creative ways to spruce up a broken down mailbox with brick, stone, paint, stain and other artistic materials, but it all starts by securing the mailbox post firmly in the ground. Without a well-grounded post, a mailbox is vulnerable to another damaging accident. QUIKRETE Fast Setting Concrete Mix doesn’t require any mixing and reaches a strength of 400 pounds per square inch in two hours making it a popular material for setting a variety of posts including mailboxes, fence posts and basketball poles.
QUIKRETE made a quick and informative video to help you set posts in concrete. Whether you are working with mailboxes, fence posts, or basketball poles, this video shows you have to easily set posts in concrete.
Set Posts in Concrete Project Instructions
The following project instructions accompany the video and provide more detail on how to set posts in concrete. Remember, when working with cement-based products, always wear eye protection and waterproof gloves.
Step 1 – Dig post hole so diameter of the hole is three 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 to 1/2 the post height above ground (i.e., a six-foot tall fence would require a hole depth of at least two feet).
Step 2 – Add about six inches of QUIKRETE All-Purpose Gravel into the bottom of the hole. Then compact and level the gravel using a post or 2×4.
Step 3 – Set the post into the hole and attach 2×4 braces to adjacent sides of the post.
Step 4 – Use a level to position the post perfectly vertical.
Step 5 – Fill the hole with fast-setting concrete up to three to four inches below ground level.
Step 6 – Pour about a gallon of water per 50 lb. bag into the hole and allow the water to saturate the concrete mix. NOTE: Mix will set hard in 20 to 40 minutes
Step 7 – Wait about four hours to begin constructing your fence or applying heavy weight to your post.
