Synko-Flex, a non-swelling, preformed adhesive waterstop is
a proven, economical alternative to conventional PVC
waterstops. Used on cold joints at footings, walls or slab
joints, Synko-Flex is simple to install and requires no split
forming, welding of splices or wiring to rebar. Its ease of
installation means substantial savings on labor costs.
Unlike bentonite waterstops, Synko-Flex does not expand or
swell through contact with water to achieve a watertight seal.
Synko-Flex achieves a watertight seal by bonding to the fresh
concrete during the curing process. Because Synko-Flex does
not rely on swelling within the joint, there is never a risk
of blowing out a joint, even if the material is not centered
properly. In addition, it is unaffected by rain, infiltrating
groundwater and cyclical water conditions.
