Sika Greenstreak Hydrotite CJ-1020-2K – Hydrophilic Waterstop
Sika Greenstreak Hydrotite CJ-1020-2K is an advanced hydrophilic waterstop designed to provide superior waterproofing performance in concrete construction joints. Manufactured from modified chloroprene rubber, this non-bentonite-based waterstop expands up to eight times its original volume upon contact with water, forming a secure, watertight compression seal. Its expansion delay coating ensures proper curing before activation, making it ideal for water treatment facilities, tunnels, foundations, and other critical waterproofing applications. With its reliable and long-lasting performance, Sika Hydrotite CJ-1020-2K effectively prevents water intrusion, even under high hydrostatic pressure conditions.
Key Features:
- Hydrophilic waterstop expands up to 8 times its original volume upon water exposure
- Non-bentonite composition ensures long-term stability and performance
- Expansion delay coating prevents premature activation during concrete curing
- Provides a durable, watertight compression seal for concrete joints
- Designed to withstand high hydrostatic pressure (up to 150' head)
- Can be used in both new construction and retrofit applications
- Easy to install with peel-and-stick adhesive backing
- Compliant with NSF/ANSI 61 for potable water applications
