As an alternative to saw cutting, place Crack-A-Joint™ into the wet concrete along the joint line (above the centre of the dowel cradle), to induce a crack to the full depth of the concrete. Crack-A-Joint™ is available in standard 3m lengths formed from GALVABOND® galvanised sheet steel to a height of 25mm. It can be supplied as a plain joint, or fitted with a permanent Rip-A-Strip™ capping in two different colours options: Black or Grey.
Features:
- Complies with the requirements of AS 3727.1:2016 Residential Pavements.
- Immediately initiates a contraction joint in the slab when placed in freshly poured wet concrete.
- Finish the slab the same day. There is no need to return the next day for saw-cutting.
- Crack-A-Joint™ will butt up to any given edge, including columns.
- Crack-A-Joint™ can be placed quickly, with precision.
- During installation, the Crack-A-Joint™ profiles remain rigid.
- Clean and quick: Crack-A-Joint™ gives the building industry an efficient alternative to traditional methods.
- Compatible with UV stabilised Rip-A-Strip™ capping, which is available in 4 colours: Black,Sandstone,Terracotta or Grey.(please specify on order)
- Crack-A-Joint™ can also be setup on stakes to provide a pour through joint during concrete placement.
- No fill required: The steel edge of the Crack-A-Joint™ profile acts as a support for the edge of the concrete and stops unsightly fraying and spalling.
- Crack-A-Joint™ is roll formed from a pre-galvanised GALVABOND® strip.
- Available in 25mm size only.
- Supplied as standard in 3 metre lengths.

Installation:
- Immediately after screeding concrete to the finished level, lay the Crack Inducer (with or without capping) with its bottom edge along the proposed joint line.
- Roll the Crack Inducer so that it is vertical and wriggle it into the wet concrete until the top edge is flush with the finished level of the slab.
