Re-Swellable Cyclic Protection: Engineered to expand upon contact with moisture, retain structural stability, shrink during dry intervals, and reliably re-swell whenever water reappears.
Controlled Hydrophilic Expansion: Generates a reliable swelling pressure inside concrete joints, permanently preventing high-head water migration through cracks and cold joints.
Temperature Stable & Non-Sticky: Does not soften or stick at elevated ambient job-site temperatures, ensuring clean handling and straightforward installation along rebar cages.
Multi-Substrate Versatility: Seals cold joints between fresh and aged concrete, connections between rigid and flexible materials, and penetrations around steel, iron, or concrete pipe sleeves.
Commercial Roll Packaging: Supplied in 25-meter rolls (4 rolls per box, 100 meters total) to support continuous joint runs on residential basements, water tanks, and infrastructure projects across Nepal.
