CE 1.8: Ponding Water on Surfaces

Surfaces which are sloped for drainage may have minor variations in the surface may impede immediate drainage and are acceptable. Standing water with a depth of less than 6 mm and in a pond less than 1m in breadth 24 hours after wetting is acceptable unless it is located in any area of the surface which cannot be easily avoided during normal pedestrian use (examples would be the area immediately beside a doorway or where an individual steps when exiting their parked car or similar) in which case any ponding remaining after 24 hours is not acceptable.

One-Year – Work and Materials

Ponding in excess of acceptable performance shall be repaired.

It is normal for water to accumulate on surfaces immediately after a wetting event. Only water which remains after 24 hours is considered ponding.
