Noticed water pooling on your driveway after rain? That’s a sign it’s not draining properly. Traditional concrete and asphalt can cause runoff, leading to erosion, flooding, and even pollution.
Permeable paving is a smarter, more sustainable option. It lets water soak through the surface and into the ground below — helping to reduce flooding, protect your garden, and ease the load on local stormwater systems.
That’s why more Australian homeowners are choosing permeable pavers for their driveways, paths and outdoor spaces.
In this guide, we’ll take a closer look at permeable paving, how it works and the best options available for your home.
Permeable paving — also called porous paving — is a type of surface that allows rainwater to pass through it, rather than pooling or running off. It’s a practical, environmentally friendly alternative to concrete or asphalt.
When water hits a traditional surface, it flows into storm drains, often carrying pollutants with it. But permeable paving works differently. It lets water soak naturally into the ground, reducing runoff, easing pressure on drains, and helping recharge groundwater.
It’s a smart option for driveways, footpaths and patios — especially in areas dealing with heavy rain, water restrictions or drainage issues.
The key to permeable paving is what’s underneath the surface. While the top layer may appear to be any other paver or gravel surface, it’s part of a carefully designed system that helps manage water flow.
It starts with small gaps between pavers or porous materials that allow rain to filter through. Beneath that is a specially prepared base — usually made from single-sized gravel — which slows the water down and guides it safely below.
From there, the water can soak into the soil, be redirected into a drainage system via pipes, or be stored in a tank for later use.
In low-traffic areas like garden paths, gravel alone is typically sufficient. But in driveways or parking spots, you’ll need a stronger base layer to support the load and keep everything draining as it should.
Permeable pavers are a versatile and sustainable solution for managing stormwater runoff in various applications. While they’re generally used for driveways, they can also be used in a variety of other settings such as:
In addition to managing stormwater runoff, permeable pavers can help reduce the urban heat island effect by allowing moisture to evaporate from the surface, keeping outdoor areas cooler. They also promote better infiltration of rainwater into the soil, which helps replenish groundwater supplies.
Permeable pavers have small gaps or porous materials that allow rain to soak directly into the ground. This helps reduce pooling, runoff, and pressure on stormwater systems – especially during heavy rain.
Beneath the surface, a specially prepared gravel base slows and filters the water. It can soak into the soil, flow into a drainage pipe, or be stored in a water tank for reuse.
Despite letting water through, these pavers are built for real-world use – including driveways and footpaths. With proper care, they can last 20 to 30 years or more.
Thanks to their modular design, individual pavers can be swapped out if damaged. Ongoing maintenance is minimal – just keep the gaps clear with occasional sweeping or pressure washing.
Permeable paving allows water and air to reach the soil, which supports healthy roots and helps recharge local groundwater supplies.
Because moisture can evaporate through the surface, these pavers don’t absorb as much heat as traditional concrete or asphalt. That means cooler outdoor areas in hot weather.
In some projects, permeable paving can reduce the need for additional drains or retention systems, freeing up space and potentially lowering installation costs.
Available in a range of colours, shapes and textures, there’s a permeable paver style to match almost any landscape – even ones that blend in with grass or gravel.
There’s no one-size-fits-all when it comes to permeable paving. Different types suit different spaces, looks and needs. Here are the most common options you’ll come across:
These are probably what most people imagine when they think of paving. They’re laid with small gaps between each piece, which are filled with gravel or sand to let water pass through. Great for driveways, paths and patios – they’re strong, neat, and easy to replace if one ever gets damaged.
Unlike regular concrete, this mix has tiny air pockets that allow water to seep right through. It looks a little rougher but works really well for larger surfaces like driveways or footpaths.
These have the classic brick look but with wider gaps between them, often filled with gravel. They’re a solid choice if you like a traditional or heritage-style finish.
These are lightweight, open-grid systems that you fill with gravel or soil. They’re perfect for overflow parking, grass driveways or access lanes where you still want greenery but need stability too.
These systems offer a natural-looking finish while reinforcing the ground underneath. Whether filled with grass or gravel, the surface is supported by a hidden grid that prevents rutting and muddiness — even under cars and foot traffic.
If you’re choosing between permeable paving and a standard concrete slab, it helps to know how they actually compare in real life.
This is the big one. Concrete is impermeable, which means water just runs off the surface. That can lead to puddles, pooling near your home, and more pressure on stormwater drains. Permeable paving, on the other hand, lets water drain through the surface and soak into the ground below — no runoff, no stress.
Winner: Permeable
Concrete may be low-maintenance until it cracks — then it becomes a major issue. Repairs often mean cutting or replacing whole sections. Permeable pavers meanwhile, can usually just replaced if something goes wrong. Due to its modular design, it’s easier to manage long-term.

Both options are tough, but permeable pavers are generally more flexible. They handle ground movement better and are less likely to crack, making them more durable in the long run. With relatively little uptick, they can last for decades.
Winner: Permeable
Standard concrete is plain by default — adding colour or texture means extra treatments. Permeable pavers, on the other hand, come in a wide range of colours, finishes and shapes. You can lay them in creative patterns like herringbone or basketweave to match your home’s style. That makes them easier to personalise and more visually appealing from the start.
Winner: Permeable
Traditional concrete sends water straight to the drain, often picking up pollutants along the way. Permeable paving helps filter that water and recharge groundwater, making it a much more eco-friendly choice.

Installing permeable paving takes a bit more planning than regular concrete, but the process is straightforward when done right.
The most important part is the base. It’s not just about laying the pavers — it’s what’s underneath that does the heavy lifting. A proper sub-base, typically made from single-sized gravel, facilitates effective water drainage and maintains the surface’s stability over time.
Soil type matters too. Sandy soils allow water to drain quickly, while clay retains moisture for longer periods. Depending on your soil, your installer might recommend one of three systems:
For smaller areas, such as garden paths or patios, DIY might be an option. But for larger spaces — especially driveways — it’s usually worth getting a professional involved. The right setup at the start can make all the difference in how well your paving performs in the long term.
To help you budget for your project, the average cost of installing permeable paving typically falls between $120 – $170 per m². While that’s usually more than plain concrete, you’re getting more than just a functional surface.
You’re investing in a drainage system, a longer-lasting solution, and a finish that actually looks good — not just a grey slab. Permeable pavers come in a wide range of styles, so you can choose something that suits your home rather than settling for basic.
Plus, in some areas, councils offer rebates or incentives for using permeable materials. And because these systems help reduce runoff, you may not need as many drains or pits, which can save you money elsewhere in the project.
So yes, the upfront cost is a little higher — but in terms of long-term value, it’s often well worth it.
Permeable paving isn’t just a trend — it’s a smarter, longer-lasting way to manage water around your home. It looks good, holds up to daily use, and helps reduce runoff, flooding and heat.
Whether you’re redoing your driveway or planning a full outdoor upgrade, it’s worth considering a surface that works with nature — not against it.
