Connolly Expansion Keyjoint
The Connolly expansion joint system is a market leader in continuous pour solutions for expansion joints in slab on ground applications. The roll-formed galvanised steel section holds the pre-adhered expansion foam in place to enable expansion joints to be set up prior to pouring. The expansion joint profile has pre-formed holes every 150mm to accommodate dowels for load transfer. Connolly universal dowel sleeves simply twist and fix into place ensuring correct alignment and spacing.
Finally, the patented peg & wedge system fixes the joint to the substrate and can be adjusted to the exact height.
