Polylok’s joint sealant system is custom-engineered to meet the most exacting standards of the pre-cast concrete industry.  Bitumen/Butyl Joint Sealant 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 in acid and alkaline environments.

Polylok’s Bitumen/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.
