Hydro-Flex® Hydrophiic Waterstops

Mastic Waterstops Installation Hydro-Flex® 302 waterstop is a preformed adhesive hydrophilic 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 up of butyl rubber, polypropylene elastomers, hydrophilic fillers and placticizers providing a more uniform and controlled volumetric expansion upon contact with water.

Packaging for hydrophilic waterstops
Hydro-Flex Waterstop is a self-adhesive and bonds to a wide variety of substrates. Its ability to swell, allows it to penetrate into poorly consolidated concrete surfaces.


Synko-Flex® Primer

The primer readily penetrates the pores and seals dusty concrete surfaces to providing an optimal surface for the adhesion and bonding of Synko-Flex performed mastic waterstops.
