Joint Sealant

Design Precast & Pipe uses only the finest joint sealants engineered to meet the most exact standards of the precast concrete industry. We use NPC Bidco C-56 Butyl Mastic Joint Sealant which remains flexible and forms a permanent bond to a wide variety of substrates including concrete, metals and plastics. Adhesion and cohesion at the time of installation are excellent and actually improve after the joint has been formed and placed into service. This sealant is designed not to shrink, oxidize or harden and has excellent resistance to temperature extremes, acid and alkaline environments.

C-56 Butyl Mastic Joint Sealant is designed to fully comply with current ASTM Standards and Specifications as required by Federal, State, and Local agencies for use by the precast concrete industry and contractors.
