Permeable concrete acts like a solid yet porous filter, allowing rainwater to pass through the surface instead of pooling or running off. The pores direct water into a base of clean screenings that store and gradually release it into the soil. This helps prevent flooding, reduces runoff, and recharges groundwater, which is especially valuable in urban areas where natural infiltration is blocked by hard surfaces.

Permeable concrete’s standout properties go beyond just allowing water through. Some of the most important attributes include:

• High Porosity – Our permeable concrete achieves strength comparable to standard concrete, reaching up to 25+MPa once fully set.
• Rapid Drainage Rates – Depending on the mix and installation, permeable concrete can drain over 100 litres of water per square metre per minute.
• Structural Strength – Permcon is a high-strength, permeable concrete ideal for various applications, including driveways, car parks, and footpaths.
• Surface Temperature Benefits – The open structure and lighter colour can reduce heat absorption, which helps mitigate the urban heat island effect.
• Low Water Ponding – Because water drains quickly through it, surface puddles are virtually eliminated.

Permeable concrete offers benefits that address both environmental concerns and practical needs:

1. Stormwater Management – By allowing rainfall to pass through the pavement, it helps reduce pressure on drainage systems during storms.
2. Groundwater Recharge – The infiltration process supports natural water cycles, especially in areas where water tables have dropped due to overdevelopment.
3. Pollution Filtration – As water passes through the concrete and underlying layers, sediments and pollutants are filtered before entering waterways.
4. Improved Safety – The quick drainage minimises standing water, reducing the risk of slips and vehicle skidding.
5. Reduced Heat Build-Up – Surfaces stay cooler in hot weather, making surrounding areas more comfortable.

Permeable concrete is highly effective for a wide range of applications, including driveways, car parks, footpaths, courtyards, residential streets, and landscaping paths. It has been successfully installed in high-load areas, including fire stations, demonstrating its durability even under heavy use.

Effective performance depends on correct installation, including proper subgrade preparation, suitable base material, and precise mix control. Regular maintenance, such as clearing debris to prevent pore clogging, will extend its lifespan. We work with architects, builders, and landscape designers to ensure each project meets site-specific requirements for both durability and function.

Permeable concrete is a practical way to manage water naturally while maintaining a strong, attractive surface. It reduces flooding, improves water quality, and supports the natural water cycle, making it valuable for modern urban planning and landscaping. Our team can provide expert guidance on applying it effectively based on your site, usage needs, and long-term goals. Understand the science behind sustainable paving.
