Parking stops, otherwise known as wheel stops or parking blocks, are simple blocking mechanisms that are meant to stop a vehicle from rolling forward when parked in a certain area. Parking stops are similar to speed bumps in the way that they are made, but they are usually taller and they have steeper sides. Speed bumps are meant to be driven over, but wheel stops are meant to actually prevent a car from moving.

How Parking Blocks Are Made
Many older models were constructed from concrete, but recently manufacturers have tried to steer their efforts toward recycled materials. Rubber and recycled plastic blocks are now used frequently, and have proven themselves to be equally efficient. Additionally, these blocks are less likely to deteriorate over time. These materials are made into long blocks of varying sizes. The blocks are shaped like trapezoids, and they are usually made to be a few inches high. can be painted in color according to specific needs.
Types of Parking Blocks
There are three types of blocks produced by the Parking Block Store, which include the recycled rubber parking block, the industrial molded commercial parking block, and the injection molded commercial parking block. An overview of the parking block selection is as follows:
Recycled Rubber Block
This block is composed of 100% recycled tires equipped with reflective panels.
It comes in 3 lengths and corresponding weights: 6 ft/40 lbs, 4 ft/26 lbs, and 3 ft/20 lbs.
The recycled rubber blocks are are 6 inches wide, 4 inches tall and include inward sloping ends to minimize tripping hazards.
The block is compartmentalized, which means that it is molded with rubber compartments underneath of the block that transmit the weight of the car to the ground. The compartments spread across the bottom create a very strong and flexible block. If a parking space is not completely flat, the rubber block with mold itself to the pavement and naturally create a flat surface.
It is available in 3 color combinations: black with reflective yellow panels, black with reflective white panels, and handicapped blue with reflective white panels.
Rubber parking blocks contain mounted holes that are counter sunk. A counter sunk hole allows the head of a countersunk bolt or screw, when placed in the hole, to sit flush with or below the surface of the surrounding material. (Wikipedia) This method ensures the safety of tires as well as provides a clean, flush appearance to the parking block.
Injection Molded Commercial Parking Block
This block is 6 ft., includes 3 fasteners per block, and weighs approximately 16 lbs per block.
The blocks are ideal for most parking lots where the vehicles are cars, vans and light trucks.
The block is 100% recycled plastic, and is not solid, yet not hollow.
Like the recycled rubber block, it is compartmentalized. This means that it is molded with rubber compartments underneath of the block that transmit the weight of the car to the ground. The compartments spread across the bottom create a very strong and flexible block. If a parking space is not completely flat, the rubber block with mold itself to the pavement and naturally create a flat surface.
Industrial Parking Block
The block is 100% solid, recycled plastic.
The block comes in two lengths and corresponding weights: 6 ft. 30 lbs and 4ft. 20 lbs.
This is the strongest most durable block carried by the Parking Block Store, and comes with a lifetime warranty against breakage.
Installation Options and Instructions
There are three separate installation fasteners included with the purchase of a parking block. The options and installation instructions are as follows:
STEEL SPIKE METHOD
12 inch galvanized steel spikes are recommended for asphalt and gravel surfaces.
Requirements for installation:
A) Solid plastic parking block
B) 1/2” x 12” plated steel spike for each hole in the speed bump
C) Two 4” strips of butyl adhesive tape (a strong sealant tape, a trimming knife)
D) A high speed hammer drill with a 3/8” masonry bit and
E) A sledge hammer for driving spikes
Note: Butyl tape is a strong sealant. The main advantage of butyl tape is that it combines the adhesive power of tape with the sealing power of caulk and other sealing products.
Steps for installation include:
A) Position the parking block in its installation position and, and, using its pre-drilled holes as templates, mark the location of each hole on the roadways surface.
B) Remove the parking block. Using a high-speed hammer drill with a 3/8″ masonry bit, drill a hole through the roadway surface at each marked location to avoid fracturing the asphalt with the spike.
C) Make sure the substrate is thoroughly clean and dry. Reposition the parking block in it’s installation position. Drive the spike through the parking block and into the drilled hole until the spike is snug against the counter gored surface of the parking block pre-drilled hole. DO NOT drive the spike beyond snug. If driven too far, spikes may damage the parking block.
LAG ANCHOR METHOD
18 inch lag anchors are recommended for older asphalt and concrete surfaces at least 3 inches thick.
Requirements for installation: A.) solid plastic parking block, B.) one 1/2” x 8” lag bolt for each hole in the speed bump, C.) two 1/2” washers for each lag bolt, D.) 1/2” lag anchors for each lag bolt, E.) two 4” inch strips of butyl adhesive tape, F.) a trimming knife, G.) a high speed hammer drill with a 3/4” masonry bit, and H.) impact wrench or heavy ratchet
Steps for installation include:
A) Position the parking block in its installation position and, using its pre-drilled holes as templates, mark the location of each hole on the roadways surface
B) Remove the parking block. Using a high-speed hammer drill with a 3/4″ masonry bit, drill a hole at each marked location to a depth of 3-1/2″ below the parking surface
C) Insert a lag anchor into each hole (large anchor opening on top.) Tap the anchor into the holes with a hammer so that the anchors are set flush with the surface. Place a washer over each anchor hole. Make sure the substrate is thoroughly clean and dry. Re-position the parking block in it’s installation position. Apply firm hand pressure. Slip a washer onto a lag bolt, insert the bolt through a pre-drilled hole in the parking block and tighten the bolt about three quarters of the way with a 3/4″ socket. Repeat for each hole in the parking block. Finish tightening each bolt until just snug. DO NOT over-tighten. Excessive tightening may damage the parking block.
5 inch Large Diameter “TapCons” or LDTs are similar to self tapping screws, and are recommended for concrete.
