Connolly Key Joints

Connolly Key Joints are an expansion joint that provides a durable and rigid straight line that can be utilised for expansion joint forming in either end of pour or continuous pour situations. They are basically a galvanized steel tongue and groove formwork which when installed joins the slab to form the control joint.

A Connolly peg and wedge system is used to hold the joint in place. Installation is quick and easy and delivers precise height adjustments. The rigid steel profiles produce straighter joints. Useful for controlling cracks on large slabs, including residential home slabs and industrial applications.

The system includes dowels, sleeves, expansion foam, wedges and pegs and is available in 6m lengths and 3 heights, 100, 150 and 200mm.

Connolly Dowel Cradles

Connolly Dowel Cradles

Dowel cradles are used for load transfer in saw cut contraction joints. They are a welded wire assembly that ensures the horizontal and vertical alignment of dowels at the correct spacing and height.

Maintaining correct alignment of dowels across the joint is recognised as being the most important aspect of forming a dowelled joint.

Connolly dowel cradles are produced with either round, square or plate dowels. All Dowel Cradles are supplied with a de-bonding sleeve to one half of the dowel to allow for contraction. Square and plate dowel Cradles also allow for lateral movement.
