Expansion Joint sealant

Expansion joint sealant is a material used to seal joints and gaps in construction projects that experience movement due to expansion and contraction. These joints are typically found in structures such as concrete floors, sidewalks, bridges, and water retaining structures where temperature fluctuations, seismic activity, and environmental changes can cause the materials to expand and contract. The sealant helps to prevent water from penetrating the joint and causing damage to the structure. Common types of expansion joint sealants include silicone, polyurethane, polysulfide, and acrylics, each with its own unique properties and applications.
