Bentonite Waterstops

HENRY HYDRO-FLEX WATERSTOP

The Hydro-Flex Waterstop is a preformed adhesive hydrophillic waterstop designed to swell in the presence of water providing a watertight seal in cold joints on concrete structures. This highly advanced product is made from butyl rubber, polypropylene elastomers, hydrophilic fillers and plasticizers providing a more uniform and controlled volumetric expansion upon contact with water. Hydro-Flex Waterstop is self-adhesive and bonds to a wide variety of substrates. Its ability to swell, allows it to penetrate into poorly consolidated concrete surfaces.

HENRY SYNKO-FLEX WATERSTOP

Synko-Flex Preformed Plastic Adhesive Waterstop is a specially formulated non-swelling preformed joint sealant that provides a long lasting, watertight bond to both fresh and cured concrete surfaces. Synko-Flex 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 footings, 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.
