Drainage is part of the construction specification, not an optional detail to solve after the driveway has been laid.
Start with one question: where will the water go?
The finished driveway should not simply move surface water toward the house, a neighbour or the public highway. The correct solution depends on levels, ground conditions, the surface system and the wider property drainage arrangement.
The driveway profile should direct water intentionally rather than relying on an apparently flat finish.
Linear drainage can collect runoff at thresholds, boundaries or low points when connected to a suitable destination.
Permeable paving or resin only works as intended when the layers beneath are also designed for storage and infiltration.
Suitability depends on soil, groundwater, available space and the wider drainage design. They should not be treated as a universal answer.
Questions to settle before accepting the quotation
- What finished levels and falls are proposed?
- Where does every channel or outlet discharge?
- Is the surface genuinely permeable as a full construction?
- What happens during intense rainfall?
- How are thresholds, garages and neighbouring land protected?
- Who is responsible for any permissions or separate drainage design?
