Driveway pavers are judged by a harsher standard than patio pavers. A car resting on four contact patches, a delivery van turning across the surface, and a winter of freeze-thaw cycles all load the pavement in ways a backyard patio never experiences.
The paver you see is only the top inch of a system. A driveway normally needs a compacted granular base 6 to 8 in (150 to 200 mm) deep, a non-woven geotextile separator, continuous edge restraint, and stabilized joint sand. A patio can often get away with 4 in (100 mm) of base and no restraint at all.
This guide covers what vehicle traffic demands from driveway pavers: which products are rated for it, how load class drives base depth, what compaction has to achieve, and what the work costs in the US, Canada, Australia, and New Zealand.

Why a Driveway Needs a Heavier Build-Up Than a Patio
Patios carry people and furniture. Driveways carry rolling and dynamic loads, and they carry them at the edges, where a wheel sits half on the pavement and half on the approach. Edge loading is what breaks under-built driveways first.
A 4,000 lb (1,800 kg) sedan puts roughly 1,000 lb (450 kg) on each wheel; a loaded box truck puts about 4,000 lb (1,800 kg) on each rear tyre. Tyre contact pressure for a passenger car runs around 30 to 35 psi (200 to 240 kPa), far below what a good paver can take. The pavers are rarely the problem. The subgrade and the base are.
Segmental paving works as a flexible pavement: load travels down through the paver, spreads laterally through the interlock, and is distributed across the base by friction between stone particles. Three things make that work.
- Interlock. Tight joints, correct laying pattern, and restrained edges stop units from rotating or migrating.
- Base thickness and stiffness. A deeper, well-compacted base spreads load over a wider subgrade area and lowers stress at the soil interface.
- Drainage. Water in the base destroys stiffness. A saturated subgrade under a loaded driveway is where ruts begin.
The failures we see most often are predictable: pavers that rock because bedding sand washed out, joints that empty every spring, edges that spread without restraint, and depressions where the base was too thin.
The Driveway Build-Up, Layer by Layer
Here is a typical residential driveway section, working from the surface down. Total build-up usually lands between 11 and 14 in (280 and 350 mm).
Each layer has a job.
- Subgrade. Scarify the top 6 in (150 mm), remove organic material and soft spots, and compact at near optimum moisture. We proof-roll and watch for pumping.
- Geotextile. A non-woven separation fabric stops fine subgrade particles migrating up into the base, which eventually kills its drainage and stiffness. On clay it is not optional.
- Base. Crushed stone with a proper gradation, compacted in lifts no deeper than 4 to 6 in (100 to 150 mm) loose. Dense-graded ¾ in (20 mm) minus is standard; open-graded stone is used for permeable systems.
- Bedding sand. About 1 in (25 mm) of washed concrete sand, screeded to a consistent thickness. Too thick and the pavers float; too thin and they cannot seat.
- Pavers. 80 mm (3⅛ in) units for anything a vehicle drives on.
- Joint sand. Stabilized or polymeric sand, fully compacted into the joints. Joints transfer load; they are not decoration.
- Edge restraint. Concrete curb or a spiked aluminium or PVC edge, anchored into the base.
Paver Types Rated for Vehicle Traffic
Not every paver sold for outdoor use belongs on a driveway. The governing questions are compressive strength, thickness, and how the unit handles water. ASTM C936 sets the baseline for solid concrete interlocking paving units at a minimum average compressive strength of 8,000 psi (55 MPa) with water absorption under 5%.
| Paver type | Governing standard | Typical thickness | Compressive strength | Water absorption | Where it makes sense |
|---|---|---|---|---|---|
| Interlocking concrete pavers | ASTM C936; CSA A231.2 | 80 mm (3⅛ in) for vehicles | 8,000 psi (55 MPa) minimum average | Under 5% | The default driveway paver. Widest availability, best cost per square metre, repairable unit by unit. |
| Heavy vehicular clay brick | ASTM C1272 | 2¼ to 3 in (57 to 76 mm) | 8,000 to 10,000 psi (55 to 69 MPa) | Under 5% for Type R | Freeze-thaw climates and heritage streetscapes. Colourfast, but usually the most expensive option per square metre. |
| Permeable interlocking concrete pavers | ASTM C936 plus infiltration testing per ASTM C1701 | 80 mm (3⅛ in) | 8,000 psi (55 MPa) minimum average | Under 5% for the unit | Lots where impervious cover is capped or stormwater retention is required. Needs a much deeper open-graded reservoir base. |
| Concrete grid pavers | ASTM C1319 | 3 to 4 in (75 to 100 mm) | Around 5,000 psi (35 MPa) | Not specified for the unit | Low-speed overflow parking and fire lanes only. Not a driveway surface for daily turning traffic. |
| Thin porcelain or stone tiles on pedestals | No vehicular standard applies | ¾ to 1¼ in (20 to 30 mm) | Not rated for vehicle loads | Varies | Rooftop terraces and patios. Do not use these on a driveway. |
Two practical points sit outside the table. Freeze-thaw durability is a separate property from compressive strength, so cold-climate buyers should ask for pavers tested to the freeze-thaw provisions of the relevant standard. In Australia and New Zealand, the AS/NZS 4456 test series and AS/NZS 4455 product series are what suppliers quote, with 80 mm the normal vehicular thickness. In North America, 80 mm units are sometimes a special order while 60 mm dominates patio stock.
Load Class, Subgrade Prep, and Compaction
Base depth should follow the load and the soil, not a rule of thumb borrowed from a patio project. A driveway on sandy gravel needs less base than the same driveway on expansive clay.
Subgrade. Clay and silt are the difficult cases. They hold water, lose strength when wet, and move with seasonal moisture changes. Add base depth, a separation geotextile, and consider a geogrid. Sandy subgrades drain well but need confinement so the base does not punch into them.
Compaction. This is where most DIY driveways fail. A small plate compactor is not enough for 8 in (200 mm) of crushed stone; a vibratory plate in the 200 to 400 lb (90 to 180 kg) class, or a ride-on roller, is what the work requires. Compact each lift at near optimum moisture.
- Subgrade: 95% of Standard Proctor (ASTM D698) is a common residential target.
- Base: 95 to 98% of modified Proctor (ASTM D1557), verified by nuclear gauge or sand cone (ASTM D1556) on larger jobs.
- Lifts: 4 to 6 in (100 to 150 mm) loose, never more. Compact each lift before placing the next.
If the driveway carries anything heavier than a passenger vehicle and a delivery van, or if the subgrade is soft, get a geotechnical assessment and a design from a licensed engineer. Base thickness for heavy vehicle loads is an engineering decision, not a supplier recommendation.
Drainage, Runoff, and Local Regulations
Water is the reason most paver driveways fail early: the surface has to shed water, and the base has to stay drained.
Build a crossfall of about 1.5% to 2% away from the house or garage, and never let the finished surface sit below the surrounding grade. Where the driveway meets a garage slab, the pavers should sit at least 1 in (25 mm) below the slab.
Permeable driveway pavers take a different approach. Water passes through widened joints and open-graded bedding into a reservoir base, then infiltrates into the subgrade or leaves through a perforated underdrain. Infiltration rate is tested in the field to ASTM C1701. Permeable systems need a soil infiltration rate that actually works and a maintenance plan, because clogged joints stop functioning long before the pavers wear out.
Regulation is the part homeowners get caught by. Many jurisdictions limit impervious cover, require on-site retention for new hardscape, or charge stormwater fees based on impervious area. In the United States, municipal stormwater programs operate under EPA green infrastructure guidance and state MS4 permits. Canadian cities publish green streets guidance, and in Australia and New Zealand, water-sensitive urban design requirements often decide whether a driveway must be permeable.
Check with your local authority before excavating; widening a driveway or adding a hardstand frequently triggers a permit.
What Driveway Pavers Cost
Prices below are planning ranges for 2026, assuming a residential driveway with reasonable truck access. USD conversions are approximate, and local pricing varies with quarry distance, freight, and supplier availability.
| Item | USD per sq ft | USD per m² | CAD per m² | AUD per m² | NZD per m² |
|---|---|---|---|---|---|
| Concrete pavers, 60 mm (2⅜ in), standard finish (material only) | $2.50–$4.00 | $27–$43 | $37–$59 | $41–$65 | $45–$71 |
| Concrete pavers, 80 mm (3⅛ in), vehicular grade (material only) | $3.50–$5.50 | $38–$59 | $52–$81 | $58–$90 | $63–$97 |
| Heavy vehicular clay brick pavers (material only) | $5.00–$9.00 | $54–$97 | $74–$133 | $82–$147 | $89–$160 |
| Permeable interlocking concrete pavers (material only) | $4.50–$7.50 | $48–$81 | $66–$111 | $73–$123 | $79–$134 |
| Fully installed driveway, 80 mm pavers including base, geotextile, bedding, restraint, joint sand, and labour | $12–$22 | $130–$235 | $178–$322 | $198–$357 | $215–$388 |
Base work is where the money actually goes. Excavation, hauling away spoil, importing and compacting 6 to 8 in (150 to 200 mm) of crushed stone, and adding geotextile can equal or exceed the paver cost. A quote that looks cheap is usually a quote with a thin base.
Where the premium is hard to justify: heavy vehicular clay brick, unless a heritage look or a municipal specification requires it. Permeable pavers are rarely worth the extra cost on their own merits; they earn their place when a regulation requires them. Standard 80 mm concrete pavers remain the best value for a normal driveway.
Installation Sequence and Common Mistakes
Order of work matters as much as materials.
- Set the finished level and confirm the fall away from buildings with a laser or string line.
- Excavate to the full build-up depth plus 1 to 2 in (25 to 50 mm), then proof-roll and compact the subgrade.
- Lay the geotextile with overlaps of at least 12 in (300 mm).
- Place and compact the base in 4 to 6 in (100 to 150 mm) lifts to the design thickness.
- Install edge restraint, spiked into the base, before the pavers go down.
- Screed bedding sand to a uniform 1 in (25 mm) and do not disturb it.
- Lay pavers to the chosen pattern, cutting edges with a wet saw.
- Compact, sweep stabilized joint sand in, and repeat until the joints are full.
- Keep vehicles off the surface until the joints have cured.
The mistakes we see most often:
- Base too thin. The biggest cause of rutting. Six inches compacted is a minimum, not an aspiration.
- No geotextile on clay. Fines migrate upward, the base loses drainage, and the surface moves within a few winters.
- No edge restraint, or restraint spiked into sand. The outer course spreads and joints open from the edge inward.
- Compacting in one deep lift. The bottom of a 10 in (250 mm) lift never reaches density.
- Wrong joint sand. Plain mason sand washes out. Use polymeric or stabilized sand rated for vehicular use.
- Ignoring the drainage path. A well-built driveway that discharges onto the garage floor is still a failure.
Sealing is optional and often oversold. A quality 80 mm concrete paver holds up for decades without it. If you do seal, wait 6 to 12 months for efflorescence to finish, and never seal a permeable driveway, because sealer fills the joints that make it work.
Regional Considerations in the US, Canada, Australia, and New Zealand
United States. ASTM C936, ASTM C1272, and ASTM C1701 are the standards suppliers and inspectors reference, with ACI guidance covering concrete practice. Freeze-thaw is the design driver across the Midwest and Northeast: base thickness goes up, drainage matters more, and de-icing salt accelerates spalling on lower-grade units.
Canada. CSA A231.2 covers precast concrete pavers, and frost penetration of 3 to 8 ft (1 to 2.5 m) means the base and subgrade have to drain reliably or heave will break the interlock. Ontario and Quebec clay soils are common, so geotextile separation is effectively standard practice.
Australia. The AS/NZS 4455 product series and AS/NZS 4456 test series are what suppliers cite, with 80 mm pavers the normal vehicular specification. High UV and summer surface temperatures make light-coloured pavers a practical choice. Expansive clay subgrades in parts of Victoria and New South Wales need deeper base.
New Zealand. AS/NZS standards apply as in Australia, and high rainfall plus coastal exposure puts drainage and joint stability first. Water-sensitive urban design requirements appear in many district plans, and local aggregate sources vary, so check base stone gradation against the specification.
Across all four markets, 80 mm vehicular pavers are stock items in Australia and New Zealand, while in North America you may need to special-order them.
Frequently Asked Questions
How thick should driveway pavers be?
Use 80 mm (3⅛ in) units for anything a vehicle drives on. Sixty-millimetre pavers are patio products and are not rated for repeated vehicle loads. Pavers should also meet ASTM C936 or CSA A231.2, with a minimum average compressive strength of 8,000 psi (55 MPa).
How deep does the base need to be under driveway pavers?
Six to eight inches (150 to 200 mm) of compacted granular base is typical for a residential driveway, with the greater depth on clay or silty subgrades. Permeable driveways need a much deeper open-graded reservoir base, often 12 to 24 in (300 to 600 mm).
Can I use regular patio pavers on a driveway?
Not reliably. Patio pavers are usually 60 mm thick, below the vehicular specification, and often laid on 4 in (100 mm) of base with no edge restraint. The result is rocking, rutting, and joint sand loss. If the area takes vehicles, specify 80 mm units.
Do I need a concrete slab under driveway pavers?
No. Segmental pavers are designed as a flexible pavement, and a rigid slab underneath changes how the system behaves rather than improving it. A compacted base, separation geotextile, and edge restraint are the correct support.
How much does a paver driveway cost?
Expect roughly $12 to $22 per sq ft ($130 to $235 per m²) fully installed in the US, with approximate equivalents of CAD $178 to $322, AUD $198 to $357, and NZD $215 to $388 per m².
Are permeable driveway pavers worth it?
They are worth it when a regulation requires them or the site needs on-site retention. They cost more, need a deeper open-graded base, and require periodic vacuuming. Where there is no runoff requirement and the soil is tight clay, standard pavers are the better spend.
