24mm x 450mm Connolly Dowel Bars – Pack of 7

Unlike traditional timber or saw-cut joints, Connolly expansion joints offer a pre-engineered, galvanised steel system that maintains alignment and integrity throughout the pour. The Connolly expansion joint system includes dowel sleeves for load transfer and expansion foam for movement control—delivering a cleaner, more durable, and code-compliant joint.

Connolly expansion joint systems are suitable for a wide variety of slab-on-ground applications, including industrial floors, commercial slabs, warehouse bases, residential driveways, and external pavements. The system adapts to different slab depths and reinforcement methods, offering a practical jointing solution across multiple sectors.To view compatible products and systems, visit our complete range of concrete materials.

Connolly expansion joints help isolate movement by allowing for thermal expansion and contraction within the slab. The integrated expansion foam absorbs stress, while the dowel sleeves ensure even load transfer between sections. This minimises the risk of uncontrolled cracking and promotes long-term structural integrity.

Connolly expansion joints eliminate the variability and labour-intensive setup associated with timber formwork. Manufactured under strict quality control, the system delivers a cleaner, more uniform joint finish while maintaining compliance with all relevant concrete jointing systems.

No, Connolly expansion joints are supplied with pre-adhered expansion foam, which provides a consistent void for movement. While additional sealants are not typically required, a joint sealant may be applied in exposed or trafficked areas to protect against debris ingress or water penetration depending on project requirements.
