A waterstop is an element of a concrete structure, intended to prevent the passages of fluids (such as water) when embedded in and running continuously through concrete joints. There are two distinct categories for waterstops: Waterstops for Movement Joints and Waterstops for Non-Moving Joints.
PVC is the industry standard for flexible waterstops, which are typically embedded across and along the joint. PVC is the most versatile waterstop material, offering the broadest design selection and is accepted under the ACI 350 “Code Requirements for Environmental Engineering Concrete Structures”. It has great inherent elasticity and is resistant to many waterborne chemicals. It will not discolor concrete or produce electrolytic action.
Embedded in concrete, PVC Waterstops span the joint to form a continuous, watertight diaphragm that prevents the passage of liquid through the joint. The waterstop must be properly selected and installed to accommodate joint expansion, contraction, and other longitudinal and transverse movements.
Features & benefits:
High tensile strength.
Superior elongation capability.
Excellent inherent elasticity and impermeability
High resistance to acids, ozone, seawater even diesel oil.
Extremely alkalis, chlorinated water and other waterborne chemicals resistant.
Not susceptible to fatigue deterioration as with metal or rubber.
High quality meet even exceed the industrials standard.
Never discolor concrete.
No electrolytic action with surrounding metals.
Capable to withstand hydrostatic pressure.
Heat weldable in conjunction with electric splicing irons.
Withstand the expansion and contraction movement of the joints.
Capable to taking care of any deflection or displacement arising caused by temperature changing or differential settlement of foundation.
Supplied in coils for easy handling with high flexibility.
Easy to install by tethering the outer flanges of the PVC waterstop to adjacent
a reinforcing bars.
Applications:
Ideal for movement joints.
Suitable for above or below grade applications.
Suitable in portable water tank.
Water and sewage treatment facilities.
Liquid retaining structures such as dams, canals water reservoirs, lock and aqueducts.
Tunnels and culverts.
Foundations and basements.
Parking decks, bridge decks and abutments.
Elevator pits, roof and floor slabs.
Primary and secondary containment structures.
