Creating a driveway or patio might seem simple, yet the surface you choose affects not only your property but also the wider environment.
Traditional hard surfaces such as tarmac and concrete prevent rainwater from soaking into the ground and instead send it rushing into drains, which can lead to flooding and water pollution.
To address these problems the government introduced Sustainable Urban Drainage Systems (SuDS) regulations and amended permitted development rules. From 1 October 2008, any new or replacement surfacing that covers more than five square metres with a non‑permeable material requires planning permission; using a permeable surface or directing water to a lawn or border usually avoids this requirement.
Choosing permeable paving helps you comply with the law and reduce runoff.
What is a Sustainable Urban Drainage System (SuDS)?
SuDS refers to a set of techniques that mimic natural drainage: instead of directing rainfall into pipes, water is encouraged to soak into the ground, be stored temporarily and released slowly or reused. Natural surfaces like grass and soil allow infiltration, whereas tarmac and concrete do not. The national SuDS standards assume compliance when a surface is permeable and not draining large adjacent areas. For most domestic driveways, a well‑designed permeable surface will therefore meet SuDS requirements without additional calculations.
Permeable paving options
Government guidance outlines three ways to create a driveway or patio that allows water to infiltrate. The simplest option is gravel or a vegetated surface; rain drains through gaps between stones and roots and these areas blend into cottage‑style gardens. Where a solid surface is preferred, runoff can be directed to a rain garden or soakaway, which is a depression planted with vegetation or a purpose‑built pit that collects and slowly releases water. The third option is modern permeable paving: porous asphalt, permeable concrete blocks and resin bound surfaces all contain voids that let water filter through into a prepared sub‑base. Such systems rely on a porous sub‑base, usually open‑graded stone or bitumen, which provides structural strength and temporary storage for rainwater, reducing runoff.
Planning regulations and compliance
Surface‑water management is a public concern, so the planning system discourages impermeable driveways. If your project covers more than 5 m² with an impermeable material you need planning permission; using a permeable surface or directing rainwater to a garden border generally avoids this. The national SuDS standards assume permeable surfaces comply when they do not drain significant extra areas, so for most domestic driveways no complex calculations are needed.

Resin bound or resin bonded?
Both resin bound and resin bonded systems combine aggregate with resin, yet only the former is permeable. In a resin bound system, the stones are mixed with clear resin and trowelled onto a porous base, leaving tiny voids through which water drains; properly installed, such surfaces can handle very large volumes of rainwater. Resin bonded surfaces are created by spreading resin onto a base and scattering stones on top, forming a solid, non‑porous layer. Because water cannot soak through, resin bonded driveways are not SuDS compliant unless additional drainage is installed.
Benefits of choosing permeable paving
Permeable paving offers more than just regulatory compliance. By letting rain soak into the ground it reduces surface runoff and the likelihood of flooding, helps replenish groundwater, and minimises puddles and ice. Resin bound surfaces are durable, weed resistant and available in many colours, so they look attractive while performing well. Choosing a permeable solution is a simple way to make your home more sustainable without sacrificing style.
Considerations for installation
Site conditions – soil type, slope and existing drainage – determine which permeable solution will perform best. Resin bound systems require a porous sub‑base such as open‑graded aggregate or bitmac, and the underlying surface must be stable. Although permeable paving is low maintenance, periodic cleaning prevents blockages and keeps it looking tidy.
Final thoughts
Complying with SuDS regulations is both a legal necessity and a chance to improve your property. Permeable paving reduces flood risk, helps protect local waterways and provides a durable, attractive surface. Resin bound surfacing, when installed on a porous base, combines performance with visual appeal and handles heavy rain with ease.
