How to Install Parking Blocks, Wheel Stops and Rubber Parking Curbs

By Michael Coderre, Roadly, Edmonton. Last updated 13 November 2026.

A rubber parking curb (also called a wheel stop, parking block or curb stop) is fastened to the pavement through four recessed holes. The fasteners you use depend on the surface: concrete, asphalt or gravel. This guide covers the hardware for each surface, the tools you need, the steps, where to place the curb, and the questions that come up most.

The short version: which fasteners for which surface

Surface	Fasteners that work	Note
Concrete	Concrete screw anchors (such as Roadly's Torpedo Bolts), lag bolts and anchors, or wedge bolts	Wedge bolts are for concrete only
Asphalt	Steel spikes, concrete screw anchors (such as Roadly's Torpedo Bolts), or lag bolts with anchors	Use lag bolts and anchors if the curbs must come out for winter
Gravel	Steel spikes only	Lag bolts and wedge bolts need a solid base

Fasteners are sold separately from the curb.

How far from the curb or wall should a wheel stop go?

Set the curb 2 to 3 feet back from the curb or wall, which is the usual placement. That lets a vehicle's front wheels stop before the bumper overhangs whatever is behind it. Place it parallel to the curb or wall and centred on the stall, one 6 foot curb per stall, and leave a gap between curbs in a row so meltwater and grit drain.

Tools and hardware you will need

• Hammer drill with a masonry bit sized to your fasteners
• Sledge hammer (steel spikes and lag anchors)
• Impact wrench or ratchet with a socket (lag bolts, wedge bolts, screw anchors)
• Broom and dustpan, or compressed air, to clear the drilled holes
• Fasteners for your surface, four per curb

How do you install a rubber parking curb on asphalt or gravel with steel spikes?

Place the curb, drill four pilot holes through its recessed holes, lift it away and drill each hole to the depth of your bit, clean the holes, set the curb back, and drive a steel spike into each hole with a sledge until flush with the top of the curb. Use this method on asphalt and gravel.

Tools and hardware: steel spikes, sledge hammer, hammer drill with a masonry bit matching the spike size.

1. Decide where the curb goes. 2 to 3 feet back from the curb is average.
2. Set the curb on the surface, parallel to the curb.
3. Use the hammer drill to drill through the curb and make 4 pilot holes.
4. Remove the curb and drill the holes to the depth of your drill bit.
5. Sweep each hole and remove loose debris with a broom and dustpan.
6. Place the curb back over the holes and put a spike in each hole.
7. Tap each spike in with the sledge until it is flush with the top of the curb.

How do you secure a rubber wheel stop to concrete with lag bolts and anchors?

Drill four pilot holes through the curb, remove it, drill each hole 4 to 5 inches deep, clean out the dust, replace the curb, tap a lag anchor into each hole until flush, then thread in the lag bolts and tighten with an impact wrench or ratchet. This is the usual concrete method, and it also works on asphalt when the curbs need to come out for winter.

Tools and hardware: lag bolts and anchors, hammer, impact wrench, socket, hammer drill with a masonry bit.

1. Decide where the curb goes (2 to 3 feet back from the curb).
2. Set the curb parallel to the curb.
3. Drill 4 pilot holes through the curb.
4. Remove the curb and drill the holes 4 to 5 inches deep.
5. Clean each hole with a broom and dustpan.
6. Place the curb back over the holes.
7. Tap a lag anchor into each hole with a small sledge until flush with the surface.
8. Thread a lag bolt into each anchor, hand tighten, then finish with the impact wrench or ratchet.

How do you install a wheel stop on concrete with wedge bolts?

Drill four pilot holes through the curb, remove it, drill each hole 2 inches deep, clean the holes, set the curb back, insert a wedge bolt in each hole, and tighten until the curb is snug. Wedge bolts are for concrete only.

Tools and hardware: wedge bolts, impact wrench, socket, hammer drill with a masonry bit.

1. Decide where the curb goes (2 to 3 feet back from the curb).
2. Set the curb parallel to the curb.
3. Drill 4 pilot holes through the curb.
4. Remove the curb and drill the holes 2 inches deep.
5. Clean each hole.
6. Place the curb back over the holes.
7. Put a wedge bolt in each hole.
8. Tighten the bolts until the curb is snug.

How do you install a curb with concrete screw anchors on concrete or asphalt?

Drill each hole with a carbide bit the same diameter as the anchor, a little deeper than the anchor will go so the dust has room to settle, blow the hole clean, put the anchor through the curb and into the hole, then tighten until the washer head meets the curb. Roadly's Torpedo Bolts are set this way and work on both concrete and asphalt.

1. Drill the hole with a carbide drill bit (ANSI B212.15) the same diameter as the anchor, to the minimum overdrill depth in the table on the product page.
2. Blow the hole clean with compressed air.
3. Insert the anchor through the curb and into the hole.
4. Tighten until the hex washer head contacts the curb.

Watch for: use each screw anchor one time only, because reinstalling wears the threads and lowers holding strength. An oversized hole reduces how well the threads grip.

Rubber, concrete or plastic parking blocks: which should you choose?

Rubber suits most lots in a freeze and thaw climate because it flexes instead of cracking. Concrete blocks take on water, freeze and break apart from the inside, and snowplows catch their edges. A rubber curb is also far lighter to carry and fit. Recycled plastic blocks are a third option; Roadly sells rubber.

	Rubber (Roadly curb)	Precast concrete
Weight	35 lb (15.9 kg) for the 6 ft curb	145 kg (320 lb) for a 7 ft precast curb from a local supplier (Westcon 7SPC, per its spec sheet)
Cracking and chipping	Flexes and returns to shape	Chips, cracks and crumbles; rebar can be exposed
Visibility	Reflective stripes embedded in the rubber	Paint fades after a season or two
Handling	One person can carry and set it	Needs lifting equipment for a block this size

The weights compare a 6 ft rubber curb with a 7 ft concrete one, because that is the standard size the local precast supplier lists.

Pros and cons of rubber parking curbs

• Pro: flexes under a hit and returns to shape, so no cracking, spalling or exposed rebar.
• Pro: light enough to carry and fit: the 6 ft Roadly curb weighs 35 lb.
• Pro: embedded reflective stripes in yellow or blue that stay visible.
• Pro: made from 95% pre and post consumer recycled rubber plus 5% virgin SBR.
• Con: fasteners are not included, and you need the right ones for your surface.
• Con: on asphalt, driven spikes are harder to pull out, so choose lag bolts and anchors if the curbs must be removed for winter.

Common questions

How many bolts does a rubber parking curb need?

Four. The Roadly 6 ft curb has four reinforced, recessed bolt holes on a 1,660 mm (65.35 in) span, with the outer holes 510 mm (20.08 in) apart, so it takes one fastener per hole.

How many curbs do I need per stall?

One 6 foot curb per stall is standard, centred on the stall so both front wheels contact it. Count your stalls, add a few spares, and order in one go. Bulk pricing applies on 20 or more.

Can rubber parking curbs go on asphalt?

Yes. Use steel spikes, concrete screw anchors such as Torpedo Bolts, or lag bolts with anchors. Choose lag bolts and anchors if you will remove the curbs for winter snow clearing.

Can I remove the curbs for winter?

Yes, if you fasten them with lag bolts and anchors. Driven steel spikes are harder to pull out.

Are fasteners included with the curb?

No. Roadly sells the curb and the Torpedo Bolts concrete screw anchors separately, and the anchors work on both concrete and asphalt. For spikes, lag bolts or wedge bolts, use hardware that suits your surface.

What size is a rubber parking curb?

The Roadly standard curb is 1828 x 150 x 100 mm (72 x 5.91 x 3.94 in) with a 50 mm base thickness and 53 and 45 degree chamfers.
