Swellable Waterstop Tape

Ensure long-term durability and watertight integrity for your construction projects with our Swellable Waterstop Tape. This specialized hydrophilic material is engineered to absorb water upon contact, expanding significantly to fill gaps and seal construction joints effectively. It serves as a critical component in waterproofing systems for basements, tunnels, and underground structures where static and dynamic joints require reliable sealing.

Key Features

• Hydrophilic Action: The tape contains super-absorbent polymers (SAP) that swell when exposed to moisture, creating a tight mechanical seal against water pressure.
• Strong Adhesion: Features a high-tack acrylic adhesive backing that bonds securely to clean, dry concrete surfaces, ensuring no delamination over time.
• Flexible & Durable: Maintains flexibility in various temperatures, accommodating minor structural movements without cracking or losing sealing capability.
• Easy Installation: Can be easily applied to formwork or cast-in-place joints, reducing labor time and complexity compared to traditional waterstops.

Applications

Ideal for use in construction joints of underground parking lots, sewage systems, water reservoirs, and foundation walls. It is also suitable for sealing around pipe penetrations and cold joints in concrete structures to ensure comprehensive waterproofing.
