Rubber Waterstop is an engineered elastomeric strip designed to prevent water leakage and seepage through concrete joints. Commonly installed in expansion and construction joints, it is used in various water-retaining and underground structures such as basements, water tanks, tunnels, dams, sewage plants, and retaining walls.
Rubber Waterstop acts as a waterproofing barrier, embedded in concrete during casting, and functions as an internal seal to accommodate movement while maintaining watertight integrity.
🔍 FUNCTIONS:
-
Prevents water ingress at construction or expansion joints.
-
Absorbs structural movements caused by pressure, temperature changes, and vibration.
-
Enhances the long-term durability of below-ground and water-retaining structures.
📐 TYPES AVAILABLE:
-
Center Bulb Type – Designed for expansion joints with high movement tolerance.
-
Flat Type (Edge Type) – Suitable for static construction joints with minimal movement.
-
Perforated/Eyelet Type – Allows easier anchoring using wire or rebar during installation.
