Flexverse Hydrophilic swell bar
The Flexverse® hydrophilic swell bar is a water stop that can be used to stop water ingress through cast-in-place concrete construction joints and penetrations in concrete. The profile has a sophisticated hydrophilic structure, which has been engineered to swell on contact with water and exert pressure against the ingress inside the structure. This forms an effective sealing system that can bar water entering even through the most microscopic cracks and penetrations. Flexverse® hydrophilic swell bars are crafted to have a robust build, and possess a unique reversible chemistry that ensure our swell bars can endure repeated cycles of wet-dry expansion and contraction in the long-run, while retaining their properties.

Pre-installation
FLEXVERSE® hydrophilic swell bars should be stored in a cool, dry and well-ventilated place. The application surface must be cleaned, free from all grease, dirt and debris, and dried completely. A rough surface is preferred for better gripping.
Application
The swell bar can be secured horizontally or vertically, and should be positioned on the joint leaving at least 3-inch concrete coverage on all sides, to allow for safe build-up of expansionary pressure. Continuous contact with the surface must be maintained to maximise the sealing capacity, and to prevent any displacement. This can be done with the use of suitable adhesives and/or other mechanical fasteners, like nails.
Completing installation
Concreting should be done shortly after application, to avoid premature swelling. The concrete around the swell bar should be vibrated systematically to obtain impermeable, void-free concrete in vicinity of the joint, and to maximise contact between the concrete and water bar.
