AquaBond's new, patent-pending S-Stitch Concrete Crack and Fracture Repair System for swimming pools and decks is far more versatile and faster to install than other concrete repair staple or stitch systems. You'll save tons of time by grinding shallower and narrower channels than old-style steel staples require - and shallower invasion reduces microcracking. You can even double up, or crisscross S-Stitches for amazing resistance to future movement!
