If you are planning a new permeable driveway, the question that matters most for your calendar is how long you will be without one. That includes where the car goes, when the kids can ride their bikes again, and whether you need to book time off work.
For a typical residential driveway, the work on site takes around three to five days. That covers excavation, the stone base, formwork and the pour. Then the new surface needs about a week of curing before it is ready for cars. From the first dig to the first drive, most homeowners should allow about two weeks. Larger, sloping or clay sites can take longer.
A typical installation, step by step
The timeline below is based on a standard single-home driveway of around 40 to 60 m² on reasonably level ground.
| Stage | Typical time | What happens |
| Remove old driveway (if any) | Half to 1 day | Break up and remove existing concrete or pavers |
| Excavation and subgrade | 1 to 2 days | Dig to depth, level the ground, lightly compact |
| Geotextile and stone base | 1 to 2 days | Lay fabric, then place and compact clean stone in layers |
| Formwork and edges | Half to 1 day | Set out edges and levels, often alongside the base work |
| Pour and compaction | 1 day | Place, compact and cover the permeable concrete |
| Curing under cover | About 7 days | Slab stays covered while it gains strength |
Permeable driveways usually need a deeper excavation than a standard slab, because the stone base doubles as water storage. Our article on excavation depths for the stone base explains why.
Pour day moves quickly
Pour day is short but intense. Permeable concrete has very little paste, so it starts to dry out quickly once it leaves the truck. Each load needs to be spread, compacted and covered with plastic promptly. There is no long trowelling session as with a standard slab, so a small driveway can be poured and covered within a few hours.
Some things help pour day go smoothly:
- Confirm the delivery time and site access in advance
- Have enough crew on site to place each load quickly
- Have plastic sheeting ready before the first truck arrives
- Avoid booking a pour on a forecast hot, windy or wet day
Getting the order right also avoids delays. Use our tool to work out your driveway volume, and check what to have ready when booking concrete.
When can you use it?
Curing is where patience pays off. A permeable slab that dries out or is used too early has a weaker surface for its entire life.
| Use | Typical waiting time |
| Walking (carefully, once covers are lifted) | After about 3 days |
| Cars and light vehicles | After at least 7 days |
| Heavier vehicles, trailers, caravans | Longer, as advised by your installer |
In cold weather, concrete gains strength more slowly, so allow extra days. For more on how weight affects a new slab, see when the slab is ready for heavier vehicles.
What can add time?
Permits. If a new or changed crossover is involved, most councils require a permit before work begins. Allow time for crossover permits from council, as well as any planning or building approvals.
Weather. Rain on pour day usually means rescheduling. Hot or windy weather shortens the working window and can mean an earlier start.
Clay soils. Underdrains connected to stormwater add digging and plumbing time.
Slopes. Check dams in the base and drains at the low end add extra work. Our article covers the extra steps on sloping blocks.
Access. Narrow side access or no room for trucks may mean barrows or a pump, which slows placement.
Size and complexity. Long driveways, curves and multiple sections take longer to form and pour.
How it compares with a standard driveway
The overall timeline is similar to a standard concrete driveway, but the time falls in different places. Permeable driveways usually take longer at the base stage, because the excavation is deeper and the stone base is laid in layers. Pour day is often quicker, because there is less finishing work. Both need around a week before cars can drive on them.
Planning tips for homeowners
- Arrange parking. Plan for about two weeks with the car parked on the street or elsewhere.
- Tell your neighbours. Trucks and machinery may block the street for short periods.
- Pour last if building. On a new home, schedule the driveway after landscaping so it is not damaged by machinery or sediment.
- Keep the covers on. Resist lifting the plastic early to check on it. That week of curing matters.
Frequently asked questions
How long does it take to install a permeable driveway?
Around three to five days of work on site for a typical home, plus about a week of curing before you can drive on it.
Can I walk on permeable concrete the next day?
It is best to wait about three days, and to walk carefully once the covers are lifted.
What happens if it rains on pour day?
Light rain after the slab is covered is generally fine. Heavy rain during placement can wash paste off the stones, so pours are usually rescheduled.
Is a permeable driveway quicker to install than plain concrete?
The total time is similar. Base work takes longer, but finishing on pour day is quicker.
