What does a drive drainage job involve?
Drainage for block paving makes sure rain leaves the surface in a controlled way: falls in the paving direct it, channel drains collect it across openings, and a soakaway or approved connection takes it away. Standard block paving sheds most of its rain, so a drive without a plan for the water ends up with puddles, wet thresholds or water running onto the pavement.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.
- Levels survey and a falls plan
- Linear channel drains with gratings rated for cars
- Connection to an existing surface water gully where permitted
- Soakaway crates or rubble soakaways where ground allows
- Threshold drainage at doors and garages
What the survey covers

- Ground conditions for any soakaway
- Load ratings needed for covers and gratings

Rules for front drives in Gwynedd
In Wales, any new or replacement hard surface at the front of a house should be permeable or drain to a permeable area within the property to avoid needing planning permission. Unlike England, there is no 5 m² allowance for new paving; only repairs of up to 5 m² of existing surface are exempt.
Since January 2019, construction work covering 100 m² or more with drainage implications, including drives and patios, needs approval from the local SuDS Approving Body (SAB) before work starts, even where planning permission is not needed.
A dropped kerb needs your council's approval as highway authority, and a new access onto a classified road needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.

Drainage in Gwynedd: questions
Can this be done at the same time as a new drive in Gwynedd?
Yes, and it usually should be, so the levels match and the paving is only disturbed once.
Who approves a drive drainage job in Gwynedd?
For a dropped kerb, your council as highway authority. For drainage and covers on private land, no approval is usually needed, but connections to public sewers need the water company's consent.
