Porous Lane

Porous Lane can be used for any of the following applications:

• Car Parks

• Driveways

• Access Lanes

• Tree Surrounds

• Footpaths/Shared User Paths

• Bike Lanes

• Nature Strips

• Schools

• Golf Cart Paths

• Terraces

• Roof Gardens

• Paved areas where a permeability requirement or reduction in runoff is desired

Porous Lane is not suitable for use in roads.

Porous Lane can provide multifaceted benefits to projects including:

• increased site permeability

• significantly reducing runoff

• flood mitigation

• reducing urban heat island effects

• treating stormwater

• lower carbon footprint than concrete or asphalt

• less excavation requirements for pavements near tress/TPZs

• highly resistant to cracking around tree root movement

Porous Lane is a unique engineered material that is the outcome of several years of research and testing at the University of Melbourne.

The result is a durable high-performance material that:

• is 8-10x more permeable than the ASCE guideline

• has a higher compressive strength than asphalt

• is semi-flexible and highly resistant to cracking

Porous Lane is also made of 40-60% recycled tyre material, contributing to the circular economy.

Porous Lane’s design life is comparable to asphalt: 20-25 years.

Porous Lane is made from a combination of recycled tyre aggregate, bluestone and our proprietary engineered polyurethane binder.

Porous Lane sources recycled tyre aggregate from Tyre Stewardship Australia accredited processing facilities. The chemistry of the tyre aggregate is controlled to ensure the same performance across all Porous Lane installations.

In the interests of making the material as sustainable as possible, tyre aggregate is sourced from the closest facility to all installations.

Yes, Porous Lane can provide input into design in order to help achieve the most cost-effective outcome.

Porous Lane is mixed on site and installed by hand. It is a cold mix, unlike asphalt.

It takes approx. 8-12 hours to fully cure and is typically usable the day after installation.

Porous Lane can interface with asphalt or concrete in several ways.

• It can abut directly against concrete or asphalt, using a sealing binder if required.

• A concrete beam can be used if desired

• A membrane or sealing binder can be used to ensure water doesn’t flow underneath existing asphalt (typically in a car park setting).

Porous Lane can contribute to sustainability in many ways.

• It is made from 40-60% recycled tyre particles, contributing to the circular economy and creating demand for a problematic waste stream

• It can reduce runoff, mimicking natural infiltration and restoring water to the ground table

• It can treat stormwater and reduce pollutants in waterways

• It can contribute to faster establishment of urban canopy through passive irrigation

• It can reduce urban heat island effects

• It has a lower carbon footprint than concrete or asphalt

• It can result in longer lasting assets near established trees

• It can reduce the depth of excavation required, retaining soils

Porous Lane’s costs vary depending on the application and corresponding thickness. As a high-performance circular economy material, Porous Lane’s up-front costs are typically more than asphalt or concrete.

When whole of life aspects are considered alongside performance benefits, Porous Lane is a highly cost effective material.

When compared with other, less well performing permeable surfaces, Porous Lane is a cost-effective option.

All permeable pavements are vulnerable to clogging if not maintained. The lower the permeability, the more quickly materials will clog.

Porous Lane has an advantage due to its very high permeability – it will remain above ASCE permeability guideline for at least five years, and can be easily maintained.

Porous Lane requires street sweeping once every 6-12 months to maintain optimum permeability,

Permeability can also be maintained by pressure washing or vacuum sweepers.

Porous Lane improves stormwater quality by filtering pollutants and trapping particles in the pavement.

One study indicate that Porous Lane removed nitrate as nitrogen by 95%, total suspended solids by 66% and heavy metals (up to 89%).

Leachates from Porous Lane have been studied according to EPA guidelines, with tested leachates either not detected or well below EPA levels.

This is due to the tyre particles being inert as they are encased in binder during he mixing process.

A Porous Lane node can be set up in MUSIC.

Once infiltrated through the permeable layer, the intent of the design guides what happens to the water in the system.

Depending on the desired outcomes water can:

• Be directed into an adjacent tree pit or parkland

• Be directed into water tanks.

• Exfiltrate into the subgrade (depending on the type of subgrade eg. this is not possible with clay)

• Be redirected back into the stormwater system

While there is currently no facility that can recycle Porous Lane, we have established in small quantities that it can be recycled back into Porous Lane mix.
