When I first started working in the construction industry it was with roofing contractors and often you hear strange terms such as “ponding” when, in retrospect, make perfect sense.

Ponding is a condition prevalent with flat, built-up roof systems where there are drainage issues but it is not a term solely used on roofs, it can be used to describe water pooling in a parking lot, too.

According to the Construction Dictionary, 9th Edition © 2001 published by the Greater Phoenix, Arizona Chapter #98 of the National Association of Women in Construction lintel is defined as follows:

(1) Curing method for flat surfaces whereby a small earth dam or other water-retaining material is placed around the perimeter of the surface and the enclosed area is flooded with water.  (2)  The gathering of water at low or irregular areas on a roof.
