What is permeable concrete?
Permeable concrete (sometimes called pervious or open-graded concrete) is formed so rainwater can pass through the surface and into a prepared stone sub-base underneath, rather than sitting on top or running straight to the road.
For driveways in flood-prone areas or close to rivers and streams, a permeable concrete base helps manage surface water sensibly as part of a wider drainage plan for the property.
Where permeable concrete works well
- Driveways in mapped flood zones or areas that regularly hold water.
- Homes close to rivers or streams, such as some parts of Chertsey, Yalding and Tonbridge.
- Parking areas where standard concrete or tarmac has caused runoff or pooling.
- Driveways where you plan to add resin or another permeable surface on top later.
Every plot is different, so we always look at levels, soil type and existing drainage before suggesting a specification.
Guide price for permeable concrete driveways
Permeable concrete driveway base: starting from £60 per m²*
*Guide prices are based on larger areas with reasonable access and generous m² measurements.
Resin Overlay — from £40 per m²*
*Based on larger areas with a sound existing surface and generous m² measurements. Smaller or awkward layouts are priced once we've seen them properly.
Final costs depend on excavation depth, sub-base thickness, geotextile layers, reinforcement, edging, manholes and how surface water needs to be managed on your plot.
