Commercial Permeable Paving with
TRUEGRID® PRO PLUS S-Flex 48
When it comes to commercial applications, permeable paving needs to do more than just manage water. It must withstand heavy traffic, protect the environment, and deliver long-term value. The TRUEGRID PRO PLUS S-Flex 48 is engineered to meet these challenges, offering a proven alternative to concrete and asphalt for car parks, accessways, and industrial yards.
Businesses, councils, and developers across Australia are turning to permeable pavers because they address long-standing issues with stormwater runoff, flooding, erosion, and pollution that are associated with traditional hard surface pavements like concrete and asphalt.
At the forefront of this shift is the TRUEGRID® PRO PLUS S-Flex 48 – a high-strength gravel and grass grid system designed specifically for heavy-duty commercial use. Engineered to combine exceptional load bearing capacity with proven stormwater performance, PRO PLUS has been successfully deployed in car parks, access roads, tree surrounds, and industrial sites nationwide.
Why Permeable Pavement is Essential for Modern Projects
Conventional concrete and asphalt surfaces are impermeable. When rain falls, water cannot infiltrate directly into the ground – it pools, runs off, and overwhelms stormwater systems. This creates a chain reaction of problems:
- Increased flooding risk during high-intensity rain events
- Rapid stormwater runoff carrying pollutants such as hydrocarbons, oils, and heavy metals
- Heat island effects caused by dark impermeable surfaces absorbing solar pressure
- Compaction around tree roots that threatens long-term tree health
- Erosion in adjoining unsealed areas due to uncontrolled flows
Permeable pavement addresses these issues by allowing rainwater to pass through the paving surface into a permeable base layer beneath. From there, the water is detained, filtered, and slowly released into the surrounding soil, mimicking natural drainage processes.
TRUEGRID® PRO PLUS S-Flex 48: Engineered for Commercial Applications
The PRO PLUS S-Flex 48 is specifically designed for the toughest commercial environments. Unlike permeable concrete or roll-out plastic mats, TRUEGRID permeable pavers use an interlocking grid structure with deep 48 mm cells that stabilise gravel or grass infill while maintaining 100% permeability.
Key Technical Features:
- Load Bearing Capacity – Capable of handling extreme loads from trucks, forklifts, and cranes.
- Patented S-Flex Joints – Flex with soil movement, preventing cracks and maintaining surface stability over time.
- Permeable Surface – Allows water to infiltrate directly, eliminating stormwater runoff.
- Hard Surface Durability – Functions like concrete for traffic, without the environmental impact.
- Aesthetic Appeal – Compatible with gravel, stone, or grass infill to suit different design requirements.

Environmental Benefits Beyond the Surface
Choosing permeable pavers like TRUEGRID delivers measurable environmental benefits:
- Decarbonisation – Concrete and Asphalt are carbon intensive materials, replacing concrete with PRO PLUS can reduce the Co2/kg Eq by 80% per m2 when compared to concrete.
- Improved Water Quality – Pollutants are filtered as water passes through the permeable layer and voids within the stone sub-base.
- Reduced Environmental Impact – Manufactured from 100% post-consumer recycled HDPE, PRO PLUS diverts plastic waste from landfill.
- Tree Protection – Ideal for tree surrounds, as it prevents soil compaction, allowing water and oxygen to reach tree roots.
- Heat Island Reduction – Unlike asphalt, permeable paving lowers surrounding temperatures by allowing air and rainwater circulation.
- Erosion Control – Stabilises surfaces prone to washouts, making it suitable for access roads, footpaths, and driveways.
These outcomes align with sustainability objectives and council stormwater management requirements across Australia.
Versatility Across Various Applications
TRUEGRID PRO PLUS is not limited to one type of site. Its design makes it suitable for:
- Commercial Car Parks & Parking Lots – Delivers durable, permeable surfaces with permanent parking markers.
- Driveways & Access Roads – Provides a stable surface that withstands heavy loads and frequent traffic.
- Tree Protection Zones – Prevents root damage while maintaining natural infiltration.
- Walkways & Footpaths – Creates safe, permeable pathways in parks, campuses, and public spaces.
- Industrial Yards & Construction Projects – Handles the pressure of forklifts, trucks, and storage without rutting.
- Residential Overflow Parking – Offers a more sustainable alternative to concrete for driveways and home projects.
Installation and Maintenance
Installing permeable pavers like TRUEGRID is straightforward compared to traditional concrete pavement:
- Site Preparation – Excavate and level the ground based on soil type.
- Base Layer – Place an aggregate sub-base designed for permeability and load-bearing requirements.
- Grid Installation – Interlocking system allows for fast installation without clips or staking.
- Infill – Fill with gravel, stone, or grass for the finished surface.
Once installed, maintenance is minimal. Because the grid structure prevents gravel migration, surfaces remain stable and level. Occasional top-up of gravel may be required, but the system eliminates common problems like potholes, cracks, and erosion found in conventional pavement.
Comparing Permeable Paving with Traditional Options
Many decision-makers consider permeable concrete or porous asphalt as alternatives. However, these materials often lose permeability over time as voids clog with fine sediments. They can also crack under soil movement or extreme loads.
By contrast, the TRUEGRID system:
- Maintains long-term permeability
- Adapts to soil and ground movement with flexible joints
- Supports extreme loads without structural failure
- Requires no curing time – drive on immediately after installation
This makes PRO PLUS a more reliable, cost-effective choice for both short- and long-term projects.
Case Studies: Real-World Proof
Across Australia, PRO PLUS has been proven in diverse environments:
- Capalaba Sports Club (QLD) – Delivered a car park solution around mature trees, protecting roots while creating a stable, compliant parking surface.
- Stokes Wheeler Commercial Car Park (QLD) – Enabled compliance with council permeability rules while reclaiming 500 sqm of land for heavy-vehicle parking.
- Tallebudgera Pony Club (QLD) – Provided a flood-resistant surface for horse floats and vehicles in a high water table area.
- Limeburners Boat Ramp (VIC) – Delivered a Coastal Car Park solution where water is treated prior to discharge into Port Philip Bay.
- Avalon Boat Car Park (VIC) – Poor quality coastal soils and Native Ramsar Vegetation affected the site for traditional paving methods – Tidal surges crest over the car park with no issues.
These projects demonstrate how permeable pavement is not only suitable but often the preferred choice in complex commercial scenarios.
The Future Is The Alternative To Concrete
Commercial permeable paving is more than an eco friendly buzzword – it is a practical engineering solution that addresses water management, environmental sustainability, and long-term durability.
With the TRUEGRID PRO PLUS S-Flex 48, developers and councils can achieve compliance with stormwater regulations, reduce environmental impact, and deliver paving systems that withstand the toughest commercial applications.
Whether it’s protecting tree roots, managing stormwater runoff, or creating durable car parks, permeable pavers are transforming how Australia builds for the future.
