Yes there whould be weeps and some rainscreen drainage plane. The air space located directly behind the exterior veneer should contain a rainscreen drainage system. In this exterior building envelope, a weather-resistive barrier reduces outside forces that draw the moisture into the wall assembly. When moisture does penetrate the exterior cultured veneer (thin stone, thin brick, or acrylic stucco), it is able to drain through the envelope via the space created by the drainage plane. Water exits through weeps placed as low as possible on the wall (top of window/door openings, or bottom of wall 4" above grade). No knoweldgable contractor should be doing this type of work without a drainage plan.
