Concrete Joint Filler is used to fill interior random cracks, control joints or new construction joints on horizontal concrete surfaces. Our Joint Fillers are designed specifically for industrial floor applications receiving heavy vehicle traffic, such as forklift or steel wheeled carts. Versaflex Joint Filler is flexible, accommodating small slab movement yet strong enough to protect the vertical edges of concrete from spalling under extreme loading. It can be used in exterior applications where little joint or crack movement from thermal cycling will occur. Joint Filler is recommended for repair of cracks, damaged control joints or new construction joints in cold storage facilities, freezers, and food processing plants where time and temperature are serious conditions.
