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.
