SikaSeal®-105 is a one-component polyurethane sealant engineered to deliver durable and flexible joint sealing in a wide range of construction projects. Its excellent adhesion to concrete, masonry, metal, and other common building substrates ensures reliable waterproofing and crack accommodation.

The sealant is ideal for sealing expansion joints, construction joints, and cracks in buildings, bridges, tunnels, and other civil structures. Its high elasticity accommodates structural movement while maintaining a watertight seal, protecting structures from moisture ingress and environmental damage.

With weather, UV, and moisture resistance, SikaSeal®-105 is suitable for both interior and exterior applications, making it a preferred choice for durable, professional-grade waterproofing solutions.
