Synko-Flex Waterstop is a single-component, self-sealing adhesive compound, extruded in a square cross-section between two quick- release protective wrappers. It bonds to cured concrete surfaces and fuses with fresh concrete during the hydration and curing process to achieve a watertight seal within cold joints at the footing, walls and slabs on a wide variety of concrete structures. It does not rely on swelling to achieve its watertight seal and therefore, it is unaffected by rain or wet conditions which may occur prior to joint completion. Synko-Flex also provides a simple long-term solution for effectively sealing pipes, sleeves, and collars which are embedded or cast into concrete walls or floor slabs.
