Things To Know About Permeable Paving

Permeable is usually a type of paving that allows the rainwater to seep in through the ground that is below and this is what exactly the name suggests here. 

As it passes through the fresher, cleaner water then soaks back into the aquifers and groundwater supplies having been filtered through it. 

The permeable paving then stops the rainwater from draining off into the storm water or onto the properties of your neighbors and this is a responsible choice undertaken by the environment.

How Permeable Paving Operates?

Instead of the water that is pooling on top of running the pavers off the water then seeps through what is meant through permeable paving. 

It all means being porous! Through the paving to a cleansing layer of the gravel, water then percolates such as it would be in a coffee pot.

Permeable paving usually works on handling the rainwater and by reducing the pressure that is there on aging on the overlooked drainage system. 

It works in two ways that are either by helping the rainwater to disperse as quickly into the ground or by holding onto it and allowing it to seep out gradually.

Why is Permeable Paving Required?

There are the heavy metals, hydrocarbons, oil, rubber, fertilizers, and pesticides that usually builds up on the paver during those dry weather. 

When the rain pours down the pollutants then ends up in the downstream of the river where the habitats of the wildlife are usually damaged. 

To cause flash floods, erosion, and greater levels of damage will happen with a heavier downfall of rain. 

The amounts of the pollutants that enter the water cycle and the amount of water that is minimized, permeable paving helps in a lot working on it. 

It helps to reduce overall irrigation demand

The direct and areas surrounding all will require less man-made irrigation when water is allowed to seep into the ground. This will thereby help you to save a lot of water and money that is required for irrigation.

It helps to reduce local ambient temperature

The sun and heat are reflected through the permeable surfaces thereby reducing the local ambient temperature. This will also be improving the health of the surrounding vegetation and will also be improving the air quality. 

Controlling erosion

Permeable paving can well be utilized for the retention of soil and in the prevention of soil erosion in the areas with looser soil and that receives heavier rainfall.

Reduces peak rates of discharge

To re-establish a further a balance in hydrology and reducing the volume of the runoff permeable paving helps in a lot. So get them done by the pavement construction Sydney services.

Why doesn’t every home head for permeable paving?

While there are several benefits to permeable paving there are certain factors that hold them back from becoming mainstream in Australia and they are:

Lack of sufficient knowledge-

Australia usually does not require permeable paving when compared to its counterparts in Germany, England, and the United States. 

But they are required in certain places. In Australia, it’s down to personal choice and many architects and homeowners simply don’t know enough about the benefits of permeable paving.


The installation of permeable paving requires a large amount of sub-grade work which generally makes it a more expensive solution compared with traditional paving systems. 

Many people fear that permeable paving comes with higher maintenance costs too, but this is debatable. Oil, grease and fine organic and inorganic matter can build up within the gravel, filling the drainage openings, but regular sweeping will reduce this risk.


Permeable pavers aren’t as strong as traditional or asphalt pavers and if you put consistent pressure on them the pores of the paving can collapse. 

For this reason, permeable paving isn’t recommended for highways and high traffic roads or for driveways where heavy loading vehicles park. Driveways for standard vehicles are fine.


  • Permeable paving has many applications, most commonly:
  • Low-volume pavements
  • Residential roads and driveways
  • Sidewalks
  • Parking lots
  • Schools
  • Low-water bridges
  • Patios
  • Courtyards
  • Well linings
  • Tree surrounds
  • Walls (including load-bearing walls)
  • Swimming pool decks
  • Commercial and industrial environments
  • Water harvesting

There are also many types of permeable paving, all of which are used for different purposes:

Porous asphalt utilized for the removal of excess water from the highways.

Single-sized aggregate (commonly known as loose gravel) is seen in very low-speed applications such as driveways or pathways.

Natural stone is used for its beauty, durability, and function. The effect lends itself to an old-world, hand-crafted look that meets modern and environmental standards.

Plastic grids allow for a 100% porous system and can help reinforce gravel driveways, parking lots, and fire lanes. Plastic grids can also be planted with grass.

Permeable interlocking concrete pavers are individual units that can be laid out in an interlocking grid pattern, with grass or small stones filling in-between spaces.
