 The Contractor should rake the joints and wet the brick or block prior to placing the plaster coat. A 0.5-inch-thick plaster coat of mortar must be applied to the outer surface of all structures and to the inner surface below the outlet flow line on all catch basins with traps and sumps. The brick or block surface must be allowed to sufficiently dry to provide for proper bonding of the plaster coat.

 === Cleanout of New Structures ===
 Drainage structures, including catch basins, manholes, leaching basins, and drop inlets installed for the project must be maintained throughout the duration. They may require cleaning by a Vac Truck or other methods. At the time of final acceptance, drainage structures must be free of silt, debris, and other deleterious material. During final inspection, each drainage structure should be marked to indicate it is in an approved condition. Cleaning of new structures is not a separate pay item.
