Connolly Key Joints

Connolly Key Joints are galvanised steel systems designed to create robust control joints in concrete slabs. The peg-and-wedge mechanism allows for precise height adjustments, while their rigid construction ensures durability. These joints are particularly suited for managing cracks in large slabs, offering stability and performance in high-traffic and industrial environments.

At Allcon, we provide Connolly Key Joints with features like:

• Easy installation
• Reliable height adjustments
• Superior steel construction

Danley Key Joints

Danley Key Joints deliver efficient load transfer between adjoining slabs, minimising deflection and accommodating lateral movement. With the “drive-n-twist” stake system and optional Rip-A-Strip™ capping profiles, these systems offer unmatched flexibility and ease of use. They’re ideal for continuous pours and projects requiring high load transfer capabilities.

Allcon stocks Danley Key Joints designed for:

• Seamless installation
• High load transfer performance
• Customisable capping profiles

A concrete key joint allows for controlled horizontal movement and effective load transfer between slabs, ensuring structural integrity while preventing uncontrolled cracking.

• Connolly: Peg-and-wedge system for secure joints and easy height adjustments.
• Danley: Drive-n-twist stakes and optional Rip-A-Strip™ capping for added flexibility.

• Concrete Key Joint: Designed to control movement and distribute loads between adjoining concrete slabs, ensuring structural integrity. Manufacturers like Connolly and Danley provide these joints in multiple sizes to accommodate different slab thicknesses.
  For instance, Danley offers key joints in sizes such as 100mm, 125mm, 150mm, 200mm, and 250mm, while Connolly provides options for slab thicknesses ranging from 100mm to 300mm.
• Expansion Joint: Allows for the absorption of thermal expansion and contraction in concrete structures, accommodating multidirectional movement to prevent cracks and structural damage.

Yes, concrete key joints manage controlled movement, reducing stress that can lead to cracks. This enhances the slab's durability.

Absolutely. Concrete key joints are versatile and suitable for residential, commercial, and industrial applications.
