If your property is located in an urban area you might need to know how to install a chain link fence over concrete. Fence post installation usually assumes that you will dig a straight hole in the ground and fill it with cement mix. If you already have a concrete slab in place, you can either cut through it or fasten the fence posts directly to the slab.

Step 1: Lay Out Fence

Determine where the corners, ends and gates will be located in the fence you are planning. These are the terminal posts and their positions determine where the line posts will go. Space out the line posts by referring to a chart or doing some simple division.

Step 2: Sink Fence Posts

To sink fence posts into dirt, dig a hole 18 to 36 inches deep by 8 inches wide. Mark the post at ground level with chalk and drop it into the hole. Pour in a concrete slurry mix and drive the post into it. Use a level to make sure the post is straight. To attach fence posts to concrete you have two options. The first is to cut through the concrete using a saw or core driller. The second option is to weld mounting brackets to the bottom of the posts. Then, sink anchors into the cement pad and screw the brackets into these anchors. Sink the terminal posts first and the line posts second, using the string to keep them in line. Allow any concrete you poured to harden before continuing.

Step 3: Attach Fittings

Slide tension bands onto the terminal posts, then add rail end bands and post caps. For line posts, install an “eye cap” or circular loop on top. Slide the top rail pipe through the eye caps and attach it to the end cap on the terminal post.

Step 4: Stretch Fabric

Unroll the chain link mesh on the ground in front of the fence posts. Slide a tension bar through the first row and fasten it to the tension bands of the terminal post. Tighten the fabric to the top rail using zip ties. It is not necessary to cut the fabric at any point; it can be modified by winding or unwinding the wire with pliers. Insert a tension bar 3 feet from the unattached end of the fabric. Fasten the fence stretcher between this tension bar and the terminal post. Stretch the fabric until it gives only slightly when squeezed. Now adjust the fabric to the exact length and connect the tension bar to the terminal post. Finally, tighten the nuts on all the brace and tension bands.

Step 5: Hang Gate

Apply the hinges to the gate posts with the pin of the top hinge pointing down and the hinge of the bottom pin pointing up. Hang the gate level with the top rail.
