Product Description
The Connolly Expansion Joint provides an efficient continuous pour solution for expansion joints in concrete slab-on-ground applications, ensuring durability and precision in construction.
Its straight profile design ensures that all load transfer occurs exclusively through the dowels, enhancing structural integrity and long-term performance.
Manufactured from roll-formed galvanised steel with a 10mm cross-linked foam insert, Connolly Expansion Joints act as a reliable leave-in-place formwork, delivering flexibility for joint expansion. The system is secured on-site with Connolly’s patented peg and wedge installation method for quick and easy setup.
This expansion joint profile features pre-formed holes for compatibility with Connolly Universal Dowel Sleeves (UDS). Using the patented twist-fix system, the Universal Dowel Sleeves can be quickly fitted into the steel section. The holes are designed to accommodate round dowels up to 30mm in diameter and square dowels up to 24mm, making the system highly versatile.
Available in 3m lengths, the Connolly Expansion Joint suits a wide range of slab thicknesses from 100mm to 200mm, providing contractors with a practical and high-performance solution for concrete slab construction.
