Crack Inducer + Grey Capping

Connolly Crack Inducers are an economical and efficient solution for controlling cracking in small concrete pours and decorative finishes. Designed to be installed directly into wet concrete, they create a controlled weak point that encourages cracking to occur neatly along the strip—eliminating the need for saw cutting or hand-tooled joints.
Manufactured from roll-formed galvanised steel, these crack inducers provide long-term durability while protecting joints from dirt, debris and moisture ingress.

Features & Benefits:
Replaces saw cuts – No need for cutting joints after curing
Controls cracking – Encourages clean, straight crack lines
Galvanised steel – Strong, durable and corrosion resistant
Permanent PVC capping – Protects joint and improves finish
Tear-off strip – Delivers a clean, slurry-free surface
Cost-effective – Saves time and labour on site

Typical Uses:
Decorative concrete slabs
Pathways and driveways
Small residential pours
Patios and outdoor areas
Any slab where controlled cracking is required

Product Details:
Lengths: 3m
Heights Available: 25mm (45mm by order only)
Capping Colours: Black or Grey with flexible PVC cap

Installation Overview:
Position crack inducer into fresh, wet concrete
Ensure correct alignment and depth before finishing

🔮ICR Pro Tip.
Concrete is going to crack — the trick is making it crack where you want it to. Connolly Crack Inducers create a planned weakness in the slab, helping direct shrinkage cracking along a predetermined joint rather than leaving you with random cracks across the finished surface.
For the best result, position the Crack Inducer immediately after screeding while the concrete is still workable, then work it vertically into the slab until the top is flush with the finished surface. Trowel around the inducer to close any voids before completing your finishing.
