How to Make Concrete Parking Bumpers

What You'll Need
Tape measure
Hack saw
Electric screwdriver
Exterior-grade plywood
Reinforcing bars
Prepackaged concrete mix
Wood glue

Concrete parking bumpers can be used for a lot of purposes. Whether you use them to stop the entry of vehicles into a certain area or just to warn a parking car that going any further would damage the car or the landscape, parking bumpers can be effectively used and are easily available. Making them yourself however is a slightly longer but cheaper process and can prove to be a fun activity too. You just need to first build a form that will shape your required parking bumper and then wait for the concrete to cure. The step-by-step guide below will further explain how the job should be done. 

Step 1 – Make the Form for the Parking Bumper 

Cut the plywood using the hacksaw according to the size you want your parking bumper to be. You need to cut the exterior-grade plywood sheet into various different sizes to make a 3D form that will hold the concrete. Cut pieces that will make the sides of the form and the bottom in a somewhat pointed pyramidal shape. That is, when the form is complete, is should look pyramidal when laid down. Exterior-grade plywood is used because it is water-resistant and appropriate for jobs like these. 

Use the electric screw driver to screw in and join together the different parts of the plywood to form the bumper’s form. 

Step 2 – Apply Glue to Form’s Edges 

Apply glue in and around the form’s edges and let the form sit for 23 hours. This will give super strength to the form and will make it withstand the weight of the concrete when poured into it. 

Step 3 – Prepare Concrete Mix 

After 24 hours, prepare the concrete mix according to the manufacturer’s instructions given on the ready concrete mix bag.

Step 4 – Pour the Concrete Mix into the Form 

Fill the wooden form halfway with the concrete mix. 

Step 5 – Add the Reinforcement Bar 

When you have filled the form halfway with the concrete mix, add the reinforcement bar to the form. Before you do this though, make sure you have cut the bar with a hacksaw according to the length of form and the bumper you wish to build. Otherwise the bar won’t obviously fit. 

Step 6 – Fill the Form and Let it Dry 

After adding the rebar, fill up the form with the concrete mix till the top and let it dry for 6 hours. After it has dried for 6 hours or until the surface is hard to touch, tip the form over and shake a little for the concrete parking bumper to slide it.  

Step 7 – Finishing the Job 

Allow the finished concrete parking bumper to cure for 48 hours. You can then take it out to your parking lot and fix it to the ground.
