Driveways · Practical advice
Where should driveway water go?
Good driveway drainage starts with deciding where rainfall will go. Explore how levels, falls, channels and permeable surfaces work together to manage water.
Start with the destination of the water
Before selecting channels or paving, decide where rainfall will go. A drain across the entrance only collects water; it still needs an appropriate outlet. Record the slope of the existing driveway, the location of thresholds and where water currently gathers during rain.
Do not assume an existing pipe has spare capacity or is suitable for a new connection. The drainage arrangement should be established before the finished levels are fixed, particularly where the house or garage sits lower than the road.
Compare surface drainage and permeable construction
An impermeable surface directs water across a planned fall towards collection or infiltration features. A permeable system allows water through the surface into supporting layers designed to receive it. The choice depends on the site, soil and drainage design, not just the name of the top material.
Permeable block paving needs compatible joints and layers. Resin bound surfacing can form part of a permeable construction, but an impermeable base beneath it changes how water is managed. Ask for the complete build-up and water route to be explained.
Check front-garden planning considerations
Government guidance for England explains that front-garden hardstanding over five square metres generally needs planning permission if it is impermeable and does not direct runoff to a permeable area. The property circumstances and any other restrictions still need checking with the planning authority. See the linked government guidance before committing to the design.
A soakaway also needs suitable ground, location and capacity. It is not simply a hole filled with rubble. Where infiltration is unsuitable, obtain advice on a designed alternative and any permissions required for its outlet.
Keep the system working
Make access for cleaning part of the design. Leaves and silt can obstruct channels, while accumulated debris can reduce the performance of permeable surfaces. Inspect after heavy rain and note whether water drains slowly everywhere or only at one point.
Ask for an explanation of inspection points and maintenance at handover. If persistent ponding appears, distinguish a blocked outlet from incorrect levels or a failing support layer. Those problems need different remedies; adding another channel without understanding the cause may not solve them.
Common questions
Is every resin driveway permeable?
No. Resin bound and resin bonded finishes differ, and the base matters. Request confirmation of the whole system rather than relying on the word resin.
Can water run straight onto the pavement?
The design should manage runoff appropriately within the agreed drainage arrangement. Check the highway and planning requirements rather than treating the pavement as an outlet.
