Exterior stucco walls built after 1975 usually end in a weep screed.
It is called a weep screed because it allows water (moisture) to weep through the holes or slots in the weep screed. As rain hits a stucco wall it is absorbed and slowly works its way to the bottom. The holes in the metal weep screed allow the water to drain.
The term screed comes from using a flat towel that rests against the metal as a guide when applying the fresh stucco.
Pavers cannot be placed above the screed and, in fact, must be 2” below the bottom of the weep screed; enough to allow the water to drain.
