D1: Eze-Crack® PVC inserted into wet concrete, flush with the surface.
D2: Removal of top section after concrete has cured and when joint sealant is ready to apply.
D3: Application of CORKJOINT® Joint Sealant and Jointflex Backer Rod into joint void.

As an indication or rule of thumb, the height of the selected Crack Inducer should be approximately 1/3rd or 1/4 of the overall slab thickness. Induced crack is impacted by concrete strength and reinforcement sizes and configurations.

1. With the use of a marker pen, mark the pre-determined position of the joint location for the concrete slab or pavement, on the top of the outside formwork on each side.
2. During concrete screeding/levelling, and while the concrete is still wet, place a string line on the mark placed on the formwork and ‘flick’ the string line to leave a slight imprint into the top of the wet concrete.
3. While the concrete is still wet, insert an aluminium or metal T-section into the concrete to form a groove into the concrete for easy insertion of the Eze- crack® PVC.
4. Remove the T-section and insert the Eze-Crack® PVC vertically into the groove. With a series of gentle push and pull movements from left to right in the longitudinal direction of the Eze-Crack® PVC, the product will slowly immerse itself into the concrete, and finish it flush with the top of the concrete surface.
5. Once the concrete is fully cured, and when the Joint Sealant is ready to be applied, remove the top section of the Eze-Crack® PVC, starting from one end and slowly lifting upwards.
6. Thoroughly clean out the joint void before inserting and applying CORKJOINT® Jointflex Backer Rod and applicable CORKJOINT® Joint Sealant. Refer to CORKJOINT® for applicable Joint Sealant for the specific project’s requirement.

Note : Eze-Crack® PVC should not be placed after full screeding has taken place but when screeding has only just passed the location and in arms reach of where the Eze-Crack® PVC is to be inserted.
