Permeable Driveway Specialists Chislehurst
If you’re considering a new driveway installation in Chislehurst, you may have encountered the term “permeable” and questioned its significance. In essence, it refers to a driveway designed to allow water to drain through its surface instead of flowing off onto the street or neighbouring properties.
Why It Matters
Planning regulations in England and Wales were updated in 2008. When installing a new driveway exceeding 5 square metres using traditional impermeable materials such as standard concrete or tarmac, planning permission is required if the area previously featured a permeable surface like grass or soil. This regulation helps prevent local drain systems from becoming overwhelmed by excessive surface water runoff.
Beyond regulatory compliance, permeable driveways offer practical advantages. They help prevent:
- Puddles and standing water accumulating on your driveway
- Water runoff flooding your garden or the surrounding street
- Overwhelmed drain systems during periods of heavy rainfall
- Ice formation during winter (water drains away instead of pooling on the surface)
Available Permeable Options For Chislehurst
Block Paving with Drainage
This is tandard block paving featuring wider joints filled with sand or gravel, alongside a sub-base engineered to allow water to pass through. It resembles a conventional block paved driveway whilst functioning as a permeable surface. Available in numerous colours and patterns.
Permeable Block Paving
This block paving variety incorporates wider gaps built into the design that enable water to run off down efficiently. It is consistently laid on fine stone grit with a permeable base constructed beneath to allow water to drain down quickly and safely.
Gravel or Shingle
The most uncomplicated permeable solution. Water drains directly through the stones into the ground beneath. It requires an appropriate base, proper edging to maintain position, and periodic top-ups, but remains cost-effective and highly functional.
Resin Bound Surfacing
A combination of aggregate and resin that produces a smooth, permeable surface. The gaps between stones permit water to drain through. It requires minimal maintenance, doesn’t shift or spread like gravel, and is available in various colours. The resin is applied on top of an open-textured tarmac or concrete base, enabling water to drain down safely and efficiently.
Grass Reinforcement Grids
Concrete or plastic grids that support vehicle weight whilst permitting grass to grow through. Ideal if you prefer a green driveway, though it requires mowing and isn’t suitable for properties with heavy daily traffic.
Permeable Tarmac
Specialist porous asphalt that resembles standard tarmac but features gaps designed to let water through. Less common for domestic driveways, but remains a viable option and is frequently used as a base for resin surfacing.
