Specifications include, but are not limited to: (89'-6" CONTINUOUS CONCRETE BRIDGE & 246'-0" PRESTRESSED GIRDER BRIDGE). This work consists of furnishing and applying a concrete penetrating sealer to a properly prepared bridge deck surface in compliance with these specifications and the manufacturer’s recommendations. A. Surface Protection and Preparation: The concrete deck surface shall be protected from contamination from dirt and debris by covering the deck with a material approved by the Engineer until such time that the surface preparation for the penetrating sealer is begun. Any materials or equipment placed on the deck during this protection period shall be placed such that there is no danger of spillage, leakage, or other contamination to the concrete surface. Concrete surfaces shall be cleaned by power washing such that all traces of laitance, dirt, dust, salt, oil, asphalt, paint, and other foreign materials and deleterious substances are removed prior to application of the penetrating sealer. In the event that oil, grease, or other contaminants are inadvertently spilled on the concrete surface, detergent cleaning along with an abrasive blast cleaning will be required on the affected areas.
