Understanding driveway permeability requirements

Permeable vs Impermeable Driveway Surfaces

Since the rules on paving front gardens changed, permeability has become a design decision rather than an afterthought. It is also genuinely useful in an area with clay soils and pressured drainage.

The good news is that permeable options no longer mean compromising on looks.

What the rules require

For front gardens, hard surfacing over five square metres should generally be permeable, or drain to a permeable area within your own boundary, to remain within permitted development.

Discharging surface water onto the highway is not acceptable. Always confirm current requirements with your local authority.

Which surfaces are permeable

Resin-bound over an open-graded base, permeable block paving with wider joints and clean stone, gravel and cellular grid systems all allow water through.

Concrete, standard tarmac, resin-bonded surfacing and blocks on a closed sand base are not permeable in themselves.

If you already have an impermeable drive

Options include directing run-off to a soakaway or rain garden within the plot, adding a permeable margin or a gravel strip, or resurfacing.

The base matters as much as the surface — a permeable finish over a sealed base does not drain.

Frequently asked questions

Is resin bound permeable?

Yes, when laid over a permeable base; over concrete it is not, and drainage must be designed.

Do I need planning permission?

Not usually for a permeable driveway, but always confirm locally for your property.

Does permeable paving block up?

Joints can silt over time; periodic cleaning maintains infiltration.
