Cross-Stitching

Cross-stitching and slot-stitching are concrete pavement repair techniques designed to reinforce longitudinal cracks and joints. Both methods use steel tie bars to stabilize the slab and prevent vertical or horizontal movement.

In cross-stitching, deformed tie bars are drilled at an angle across the crack or joint and secured with epoxy or grout. Slot-stitching, on the other hand, involves cutting narrow slots across the crack or joint and embedding the bars with grout. These approaches help maintain load transfer and add structural strength when the pavement is still in relatively good condition. They are best suited for longitudinal cracks and joints, but not recommended for transverse cracking.
