The Back-Stick Waterstop is a high-performance, self-adhesive waterproofing strip designed for quick and reliable sealing of construction joints, cracks, and leaks in concrete structures. Its pressure-sensitive adhesive backing allows for easy installation without additional bonding agents, making it ideal for repair projects and new construction where traditional waterstops are impractical.
Key Features & Benefits
✅ Instant Adhesion
Pre-applied adhesive backing for fast, no-mess installation
Bonds securely to concrete, masonry, and metal surfaces
✅ Superior Flexibility & Durability
High-elasticity rubber/bitumen composite material
Resists cracking under structural movement (±25% elongation)
✅ Wide Applications
Repair works: Seals leaking joints in basements, tunnels, and roofs
Preventive waterproofing: Applied before concrete pouring (pre-cast panels, segmental linings)
Pipe penetrations & service entries
✅ Environmentally Resilient
Waterproof immediately after application
UV-resistant (for exposed applications)
Temperature range: -30°C to +80°C
