Sealant

NPC's Bidco C-56 Joint Sealant system is custom engineered to meet the most exacting standards of the precast concrete industry. For more information, please call: 1-800-442-0141.

C-56 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 in 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 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. Its primary applications include: Concrete Pipe, Box Culverts, Utility Vaults, Burial Vaults, Septic Tanks, Wet Wells, Sanitary & Storm Sewer Manholes and Concrete Wall Panel Systems.

NPC Bidco Butyl Wrap:
To provide that extra measure of protection, NPC offers the Bidco Wrap. The wrap is applied externally to joints to stop infiltration in manholes, box culverts, septic tanks and other jointed precast structures. It is easy to apply and available in widths to fit most any application. It should be used in conjunction with an adhesive primer if wet conditions are present.
