Permeable road surfaces

There are three main types of parking solutions, with each one being specially designed to meet different criteria, while being made of different materials.

1. Permeable road surfaces are semi-permanent solutions made from a range of different permeable layers that work to filter water.
2. Pervious parking surfaces allow water to pool on the surface of the material and slowly work its way down through to the ground below.
3. Porous parking surfaces employ porous materials like gravel and sand to filter water before it is directed to a new location.

Permeable road surfaces work similarly to other permeable paving solutions, albeit on a much grander scale than footpaths and driveways.

1. Rainwater lands on the permeable parking lot, or enters the parking lot from another source, like a drain or water course.
2. Water pools on the surface of the material and begins to work its way through whichever porous or pervious layers have been purchased.
3. The freshly filtered water reaches the ground below the surface, meaning that is kept from entering overloaded stormwater systems.
4. This water can then be directed to holding facilities, to garden beds, or to aid tree roots in the local vicinity.

There are several benefits to having permeable parking surfaces around your place of business:

• Stopping excess runoff from entering stormwater systems from parking lots
• Reducing the risk of flooding from pooling water in car parks
• Lowering the temperature of the water entering the local environment
• Removing contaminants like oil and grease before the water moves on

Pervious parking solutions can also improve safety for drivers and pedestrians by removing pooling water and improving visibility around car parks. For the benefits specific to products, check out our product pages above.

The final cost of installing a permeable parking surface will depend on your chosen solution, and how much ground needs to be covered by the surface. However, the benefits of these solutions can also lead to a range of cost saving measures, including:

• Saving on water, energy, and maintenance costs
• Reducing the need for ongoing maintenance of degrading materials
• Reducing the risk of flooding across traditional parking lot surfaces
