HYDROBLOC-CJ7 is a high-performance metal plate water-stop system designed for waterproofing of construction joints in reinforced concrete structures. It consists of a galvanizediron (GI) steel plate (1.2 mm thick, 150 mm wide / 6 inches, 2 m length), factory-coated with:

• A bonding primer layer for enhanced adhesion.
• A flexible ribbed coating based on Addiflex CSH technology, ensuring superior mechanical interlock and chemical bonding with fresh concrete.

The system acts as a physical and active barrier, preventing water ingress through construction joints by extending the seepage path and ensuring monolithic bonding with concrete.

Key Features & Benefits:

• Acts as a continuous impermeable barrier at construction joints.
• Dual action system – physical barrier + bonded interface sealing.
• Extends seepage path, reducing water ingress.
• Minimizes voids and debonding at joint interface.
• High tensile strength GI steel – maintains shape during concreting.
• Resistant to displacement and deformation.
• Suitable for high hydrostatic pressure (positive & negative).
• Corrosion and chemical resistant (galvanized + coated).
• Long service life (≥ 50 years).
• Faster application vs conventional PVC water-stops.

Packaging:

Supplied in bundles. Standard size is 150mm width x 2m length.

Storage & Shelf life:

Unlimited storage period in dry, frost-free environment, protected from weather influences. Avoid damage to coating. Keep away from oil, grease and contaminants.
