Permeable Paving

Permeable paving provides significant benefits over conventional pavements in terms of sustainability, environmental impact and long-term cost.

In the natural environments, the majority of stormwater is absorbed back into the ground, recharging the local groundwater table with minimal surface run-off entering local waterways. This is not the case in urban areas.

Large areas of impermeable surfaces result in the majority of stormwater being diverted to the local waterways and very little being absorbed into the ground.
As an alternative to conventional paving, permeable paving encourages water to infiltrate through the pavement surface and substructure to the ground below, easing the pressure on already overburdened or over-stressed stormwater systems.

Benefits of Permeable Paving

• Reduces the amount of rainfall run-off by infiltration, thereby eliminating or minimising the extent of stormwater drainage systems required
• Reduces the risk of localised flooding and downstream flooding
• Assists in recharging and maintaining aquifers and natural groundwater
• Traps and treats pollutants that would otherwise contaminate groundwater
• Assists in the biological decomposition of hydrocarbon contaminants
• Reduces the size or need for rainwater retention facilities in roadworks by using the pavement itself for retention
• Allows water and air access to roots of trees and plantings
• Can be trafficked immediately following installation
• Easy access to underground services if required, without damage to laid permeable paving
• Surface gradients can often be minimised or eliminated
• Enhanced aesthetic appearance
• Paving can be recycled or re-used
• Minimises tree root damage by directing root growth down instead of along the surface, picking up moisture caused by condensation under solid surfaces
• Permeable paving provides a cost-effective alternative.

Aqua Tri-Pave

Aqua Tri-Pave provides a permeable pavement solution, allowing water to permeate into the subgrade or be collected for future use.

Case Study: City of Belmont

In 2018 the City of Belmont completed the construction of two new car parks within the Belmont Business Park; Esther Street Abernethy Road and Esther Street Robinson Avenue.

Unlike conventional carparks, the City opted to use permeable paving to capture, retain and allow the infiltration of stormwater at each car park.
