Permeable Driveway Specialists Tonbridge
If you’re considering a new driveway installation in Tonbridge, you may have encountered the term “permeable” and questioned its meaning. In essence, it refers to a driveway surface that allows water to drain through it instead of running off onto the street or neighbouring properties.
Why It Matters
Planning regulations in England and Wales changed 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 drainage systems from becoming overwhelmed by excessive surface water runoff.
Beyond meeting official requirements, there are practical advantages. Permeable driveways help prevent:
- Standing water and puddles forming on your driveway
- Water runoff flooding the street or your garden
- Drains becoming overwhelmed during heavy rainfall
- Ice forming in winter (water drains through rather than pooling on the surface)
Available Permeable Options For Tonbridge
Block Paving with Drainage
This is standard block paving featuring wider joints filled with sand or gravel, plus a sub-base engineered to allow water to pass through. It resembles a conventional block paved driveway but operates as a permeable surface. Available in multiple colours and patterns.
Permeable Block Paving
This style of paving is permeable features wider gaps built in that enable water to run off down with ease. It’s always installed on fine stone grit with a permeable base constructed underneath to allow water to drain down quickly and safely.
Gravel or Shingle
The most straightforward permeable choice. Water drains directly through the stones into the ground beneath. It needs a suitable base, proper edging to maintain position, and occasional replenishing, but it’s economical and performs well.
Resin Bound Surfacing
A combination of aggregate and resin that produces a smooth, permeable surface. The spaces between the 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 over an open-textured tarmac or concrete base, enabling water to drain down safely and efficiently.
Grass Reinforcement Grids
Concrete or plastic grids that bear vehicle weight whilst permitting grass to grow through. Ideal if you prefer a green driveway, though it requires mowing and isn’t suitable for homes 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 it remains an option and is frequently used as a base for resin surfacing.
