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 saw 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 tol 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 out.

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.
