Joint Sealant are in different types such as polysulfide is common as a sealant for bridge expansion joint systems due to its versatility. A polysulfide joint sealant is the right choice especially when no plastics are involved or when there is a possibility that the joint needs to be disassembled. Polysulfide is also suitable for bridge expansion joint repair projects, and projects that require an elastic joint sealant.
What do you fill expansion joints with?
Expansion joints must be sealed with a flexible sealant, like QUIKRETE® Self-Leveling Polyurethane Sealant or QUIKRETE® Non-Sag Polyurethane Sealant…or an expansion joint strip, to prevent water from penetrating the joint and deteriorating the sub-base.
Expansion joint sealants are known for their extreme toughness, and they are very common as industrial and construction joint sealant solutions. The epoxy resins exist in many types and they are compatible with other ingredients. The type of epoxy joint sealant most commonly used for expansion joints in bridges contain polysulfide. The epoxy polysulfide sealants are more flexible than regular epoxies and tougher than regular polysulfide sealants.
