Wheel stop installation takes 25 to 45 minutes per unit on existing asphalt and 35 to 60 minutes per unit on existing concrete. The procedure: mark the layout 30 inches off the front wall or curb, drill the anchor hole through the unit and into the substrate, set the anchor (sleeved spike on asphalt, epoxy-pinned rebar on concrete), and verify the unit sits flat with no rocking. The U.S. Access Board's ADA Standards Section 502.7.1 governs placement on accessible stalls. This guide walks through the full install on both substrates with tools, time estimates, and safety rules.
DIY wheel stop installation is feasible on small jobs (under 10 units, single substrate, no ADA stalls). For larger jobs, ADA-stall installs, or any project requiring code-stamped acceptance, hire a contractor familiar with ASTM C928 anchor adhesives and OSHA 1910.176 materials-handling specifications.
For a standard 10-unit installation:
| Tool | Spec | Notes |
|---|---|---|
| Hammer drill | SDS-Plus or SDS-Max, 1-inch capacity | Required for both substrates |
| Drill bits | 5/8-inch concrete bit (concrete substrate) or 7/8-inch carbide (asphalt) | Match anchor diameter |
| Sledge hammer | 4 to 6 lb | Drive spikes (asphalt) |
| Mixing nozzle / caulk gun | Static mix nozzle for ASTM C881 epoxy | Concrete substrate only |
| Epoxy or cementitious anchor adhesive | ASTM C881 Type IV or ASTM C928 | Concrete substrate only |
| Steel spikes | 18 inches galvanized (24 inches in freeze-thaw zones) | Asphalt substrate only |
| Polypropylene sleeves | Size to spike | Asphalt substrate only |
| Chalk line and tape measure | -- | Layout marking |
| Speed square | -- | Verify perpendicular placement |
| Rubber mallet | -- | Seat the unit |
| Compressed air or shop vac | -- | Clean drilled holes |
| Safety glasses, gloves, hearing protection | OSHA-required PPE | Per OSHA 1910.95 hearing protection and 1910.133 eye protection |
Time per unit varies by substrate and material:
| Scenario | Time per Unit |
|---|---|
| Rubber wheel stop on asphalt (sleeved spike) | 20 to 30 min |
| Rubber wheel stop on concrete (epoxy pin) | 30 to 50 min |
| Concrete wheel stop on asphalt | 25 to 35 min |
| Concrete wheel stop on concrete | 35 to 60 min |
| ADA-profile installs (any substrate) | Add 10 to 15 min for layout verification |
| Heavy-duty 8x6x84 (any substrate) | Add 10 to 20 min for equipment-assisted placement |
Measure and chalk-line the wheel-stop position. Standard setback is 30 inches from the front wall or curb to the centerline of the wheel stop. The 30-inch number reflects the front overhang of a passenger vehicle (tire to bumper).
For ADA stalls, verify the setback does not encroach on the ADA Section 502.4 36-inch wheelchair clearance.
Place the wheel stop on the marked layout. Verify with a speed square that the unit sits perpendicular to the parking-stall stripe. Center the unit within the stall width -- the wheel stop should not project into the access aisle on adjacent ADA stalls.
With the wheel stop in position, drill the anchor hole straight through the unit and into the asphalt. Use a 7/8-inch carbide bit for an 18-inch sleeved spike. Drill depth: full sleeve depth plus 1 inch for clearance. On standard 6x6x72 units there are typically two anchor holes pre-formed in the unit; drill through both.
Drop the polypropylene sleeve into the hole. The sleeve prevents the spike from spinning under load and provides a tight fit. Verify the sleeve seats flush at the asphalt surface.
Drive the 18-inch galvanized spike through the wheel stop, through the sleeve, and into the asphalt subgrade. Use a 4- to 6-pound sledge hammer; do not overdrive (overdriving compresses the asphalt and reduces pull-out resistance). The spike head should sit flush or slightly below the wheel-stop top surface.
Apply a small bead of polyurethane sealant or PL Premium adhesive at the head of the spike where it enters the wheel stop. The seal prevents water infiltration that drives winter heave.
Check the unit for rocking. The wheel stop should sit flat on the pavement with no gap or movement. If the unit rocks, the spike is at an angle or the asphalt under the unit is uneven -- pull the spike, level the substrate, and re-seat.

Same as asphalt. 30-inch setback from the front wall or curb. Verify ADA clearance per Section 502.4.
Same as asphalt. Verify perpendicular placement with a speed square.
Drill straight through the wheel stop and into the concrete. Use a 5/8-inch SDS-Plus carbide bit for a 5/8-inch rebar pin. Drill depth: 12 inches total (6 inches through the unit plus 6 inches into the concrete substrate).
Critical step. Compressed-air blow-out the hole, then brush with a stiff bristle brush, then blow-out again. Concrete dust in the hole reduces epoxy bond strength by 40 to 60 percent. Per ASTM C881 the hole must be clean and dry before epoxy injection.
Load a static mix nozzle on the epoxy cartridge. Inject epoxy from the bottom of the hole upward, filling about 50 percent of the hole volume. Per ASTM C928 cementitious anchor adhesive, mix water and powder per manufacturer ratio and pour from the bottom.
Insert the 5/8-inch deformed rebar pin into the hole, rotating slightly to coat the pin with epoxy. The pin should bottom out in the substrate. Excess epoxy will rise to the top of the hole -- that is correct, do not wipe it.
ASTM C881 Type IV epoxy cures to service load in 24 hours at 70 degrees F. ASTM C928 rapid-hardening cementitious adhesive cures in 4 hours. Below 50 degrees F switch to C928. Do not allow vehicle traffic on the wheel stop until cure is complete.
After cure, check the unit for rocking and verify the pin head sits flush or slightly below the top surface. For a deeper concrete-specific procedure see how to anchor wheel stops to concrete.
| Stall Type | Front-Wall Setback | Side Clearance |
|---|---|---|
| Standard parking stall | 24 to 36 inches | None |
| ADA standard stall | 24 to 36 inches | 36-inch wheelchair clearance |
| ADA van-accessible | 24 to 36 inches | 36-inch wheelchair clearance |
| Loading dock | Per dock-leveler manufacturer spec | None |
