Waterstops:
Canzac provides a range of waterstops, pvc for watertight joints, flexible SwellStop waterstops a waterproofing joint compound. Specially formulated preformed adhesive joint sealants such as Synko-Flex.
Synko-flex:
CANZAC SYNKO-FLEX Waterstop is a specially formulated preformed adhesive joint sealant that provides a lasting, watertight bond to both fresh and cured concrete surfaces.
 CANZAC SYNKO-FLEX is designed as an alternative to conventional waterstops that are used in cold joints at footings, walls or slab joints. Synko-Flex does not rely on swelling upon contact with fresh concrete or water to achieve its water tight seal and waterstop capabilities. Because of this, there is never a danger of a "joint blow out" due to over expansion or improper positioning.
CANZAC SYNKO-FLEX Waterstop is a non-expansive, single-component, self-sealing plastic adhesive compound, extruded in a square cross-section between two quickrelease protective wrappers. It bonds to cured concrete
surfaces and fuses with fresh concrete during the hydration and curing process to achieve a watertight seal. Once adhered, Synko-Flex is unaffected by rain, snow or infiltrating ground water which may be present during the installation period.
CANZAC SYNKO-FLEX 's unique formula and packaging provides a simple, easy-to-install solution for effective waterstop sealing. It is also resistant to acids, alkalis and hydrogen sulfide gases over the life of the structure.
CANZAC SYNKO-FLEX has been used since 1968 as a waterstop for cold joints in highway tunnels, airport teminals, marine animal theme parks, hospitals, performing art theatres, parking garages, hotels, office buildings, fish hatcheries, enclosed potable, water reservoirs, warehouses, sports complexes and wastewater plants.
CANZAC SYNKO-FLEX® WATERSTOP The approved alternative to conventional waterstops with tremendous labour savings!
PRIMER CANZAC SYNKO-FLEX PRIMER is a thin penetrating solution for premium selected asphalt base in a petroleum solvent. The primer readily penetrates the pores and seals dusty concrete surfaces to provide an optimal surface for the adhesion and bonding of Synko-Flex preformed adhesive waterstop. Primer is designed for application by brush
