Eco-friendly porous asphalt that allows rainwater to drain naturally through the surface. SuDS compliant, planning permission exempt for most properties, and eliminates standing water and puddles. The smart choice for sustainable drainage across Cheshire.
Permeable tarmac, also known as porous asphalt, is an innovative surfacing material that allows rainwater to drain directly through the surface rather than running off into drains or causing puddles.
Unlike standard tarmac which creates an impermeable barrier, permeable tarmac contains interconnected voids that enable water to pass through at rates of up to 4,000 litres per square metre per hour, far exceeding even the heaviest rainfall.
The water either soaks into the ground below (infiltration) or is collected in a sub-base drainage system and released slowly into the drainage network, reducing flood risk and helping recharge groundwater.
Water drains through the surface instantly, eliminating puddles and standing water on your driveway.
SuDS compliant permeable surfaces are exempt from planning requirements for front garden paving.
Reduces surface water runoff, helping prevent localised flooding during heavy rainfall.
Water drains away rather than pooling and freezing, reducing hazardous ice formation in winter.
Helps recharge groundwater and reduces strain on drainage systems and water treatment.
Similar cost to standard tarmac but with added drainage benefits and planning advantages.
Properly installed permeable tarmac lasts 20-25+ years with minimal maintenance required.
Occasional sweeping and annual inspection keeps your permeable driveway performing optimally.
Rainwater lands on the porous tarmac surface during wet weather.
Water passes through interconnected voids in the tarmac instantly.
Permeable aggregate sub-base temporarily stores water safely below.
Water slowly infiltrates into ground or releases to drains at controlled rate.
Understanding the key differences helps you make the right choice for your Cheshire property.
| Feature | Permeable Tarmac | Standard Tarmac |
|---|---|---|
| Water Drainage | Drains through surface | Runs off to sides/drains |
| Standing Water/Puddles | None, water drains instantly | Puddles form in low spots |
| Planning Permission | Usually exempt (SuDS compliant) | Often required over 5m² |
| Flood Risk | Reduces runoff & flood risk | Increases surface water runoff |
| Ice Formation | Reduced, water drains away | Puddles freeze in winter |
| Environmental Impact | Eco-friendly, recharges groundwater | Disrupts natural water cycle |
| Appearance | Slightly more textured finish | Smooth, uniform finish |
| Lifespan | 20-25+ years | 15-20+ years |

Yes, when properly installed with appropriate sub-base, permeable tarmac can handle normal domestic vehicles including cars, vans, and occasional delivery lorries.
With normal use and occasional sweeping, permeable tarmac maintains its drainage capacity for decades. We recommend annual inspection and cleaning if silt build-up occurs.
Material costs are slightly higher, but overall project costs are similar. You may also save on drainage requirements and planning application fees.
