Permeable Pavers
We’re doing things a little differently in the eastern Adelaide region to improve water quality for our environment. We are installing permeable pavers where we can in place of traditional paving, asphalt or concrete.
Permeable paving may look like regular paving, but they are specially designed to allow water to flow (infiltrate) through small gaps into the soil below, as would happen in a natural setting as part of the water cycle.
There are other hard infiltrating options, like stone driveways or porous rubber (often seen around trees). These are great if you’re not looking to pave, but still want to allow water to seep through to the soil and below water table.
Other hard surfaces (like asphalt and the ones mentioned above), prevent water from soaking into the ground below as water can only flow across, or, pool on the surface.
So why are permeable pavers beneficial? Permeable pavers allow rainwater to soak into soils which helps keep nearby trees and gardens alive, vibrant and healthy.
They also help to reduce the risk of local flooding after storm events, and, prevent urban pollutants from being washed into drains, local creeks and into the ocean. This improves the quality and climate resilience of the places we live, work and play.
Permeable pavers can be a cost effective solution for car parks, driveways and footpaths. Did you know they can also be used for areas carrying a heavy load too? Around the world they are being used in shipping yards!

What are thirsty pavers / permeable paving?
City of Burnside explains more about permeable paving.
Our friends at City of Mitcham demonstrate permeable pavers in action, with 2500 litres of water disappearing in just 3 minutes!
This high-density 1970 residential development’s deteriorating driveway has been repaired using permeable paving in a small section to alleviate water pooling and pavement cracking, while watering the local green space.
Located in the south-eastern corner of Greenhill and Portrush Roads, permeable paving at the Linden Gardens public carpark connects to a small wetland where treated stormwater is collected and reused for irrigation on site.
The project contributes to climate adaptation as water infiltrates into the soil below the pavers, improving soil moisture. The wetland provides quality green space for cooling, improving biodiversity and overall amenity.
A couple of other locations you can see permeable pavers include the Langman Reserve Lookout, the Mike Turtor Bikeway and George Whittle Reserve.
