Water is asphalt's quiet enemy. You notice drainage problems as pooling, ice ribbons, or potholes that always form in the same low spot.
Standing water after light rain means grade is wrong or the base has settled. Both problems get worse with traffic and winter cycles.
Water running toward a garage or foundation is a safety and structure issue — not just a pavement issue.
Drainage corrections belong in the plan before resurfacing. A new layer on a wet base fails on schedule.
