What is included?
Driveway drainage is the plan for where rainwater goes once it hits a sealed tarmac surface: the falls that move it, the channels or gullies that catch it, and the soakaway, border or approved drain that takes it away.
- Falls set across the drive, typically 1 in 60 to 1 in 80
- Linear channel at garages, doors or the bottom of a slope
- Soakaway or crate unit sized to the area and ground
- Runoff directed to borders or a permeable strip
- Connection to an existing surface-water drain where allowed
- No connection to the foul sewer
