Runoff pressure checker
Useful for the jobs that are not really “just a new surface” because the water path is already wrong before anyone starts quoting finishes.
high runoff pressure
This frontage has strong runoff pressure and should be treated as a drainage-first job.
- Runoff is not being sent into a permeable area, so standing water pressure is more likely.
- This is a non-permeable surface, so water has fewer ways to escape naturally.
- Poor fall usually increases pooling and pushes more water toward weak edges.
- Heavy shade can slow drying and make wet patches linger for longer.
What to do next
- Budget for a proper channel drain, soakaway or other drainage path before final surfacing.
- Consider a more permeable build-up or surface if the current layout is trapping water.
What to do with this resultIf this comes back high, treat the driveway as a drainage-first job and re-check the runoff route before you spend money on the finish.
