  • Circular saw

  • Electric screwdriver

  • 3/4-inch exterior-grade plywood

The inside surfaces of the wheel block form can be painted with a lightweight oil to make it easier to extract the cured concrete block and minimize saturation of the plywood.

Clean the plywood form with a wire brush and reuse it as needed for additional blocks.

Concrete wheel stops can be used in many ways. Whether you set them in a driveway to prevent encroachment into landscaping, in a garage to prevent accidental contact with interior walls or cabinets, or just use them to define the vehicle position in a parking space, building your own wheel stops can save you money and allow for custom shapes not found in standard manufactured stops. The method for fabricating a basic form can be adapted to different lengths or shapes by adjusting the dimensions to your specific needs.

The Form

Step 1

Cut two pieces of 3/4-inch plywood 5 inches wide by 6 3/4 inches long. These will be the end blocks of your concrete form.

Step 2

Mark two pieces of plywood to be cut 5 1/4 inches wide by 49 1/2 inches long. Cut one edge and both ends of these pieces with square cuts. Cut the remaining side at a 15-degree angle, keeping the 5 1/4 inches as the widest side. The opposite side should be about 5 inches wide. These two pieces will be the sides of the concrete form.

Step 3

Cut one piece of plywood 5 3/4 inches by 49 1/2 inches. This is the base of your concrete form.

Step 4

Mark the end pieces cut in Step 1 with a 15-degree angle from each side of the 6 3/4-inch width. This will create a trapezoid shape that is 6 3/4 inches on the widest side and approximately 4 inches on the opposite side. Cut these outside wedged pieces off.

Step 5

Attach the sides cut in Step 2 to the end pieces trimmed in Step 4, keeping the long point of the 15-degree cut against the end pieces (the inside of the form) and flush with the 4-inch side of the end pieces. Secure with a bead of wood glue and stitcher screws. The end of the side pieces should be flush with the face of the end pieces when assembled.

Step 6

Set the plywood form assembly on a flat surface, with the widest opening down, and attach the base plywood piece cut in Step 3 to the form, keeping the ends flush and the overlap of the side pieces equal--approximately 1/8 inch. Secure with a bead of wood glue over the perimeter of the form and stitcher screws about 6 inches apart. Let your wheel stop form sit for 24 hours so the glue can dry.

The Function

Step 1

Prepare the prepackaged concrete mix according to manufacturer's directions in a wheelbarrow or mortar box.

Step 2

Place the concrete form on a level surface and fill it halfway with concrete mix.

Step 3

Cut a piece of 1/2-inch (#4) reinforcing bar 44 inches long with a hacksaw. Lay the reinforcing bar on the concrete's surface, approximately centered.

Step 4

Fill the form with concrete mix to level with the top of the form. Use a straight piece of wood to scrape off the excess and smooth the top surface. Lightly tap the sides of the form a few times over the length with a hammer to help the wet concrete fill any minor voids. Let the concrete cure for 6 hours or until the surface is hard to the touch.

Step 5

Turn the form over and, lifting slightly on one end, gently shake the wheel stop out of the form. Use a wet sponge to smooth the surfaces. Allow your wheel stop block to cure for 48 hours.
