Fosroc Hydrotite Cj1020 2k Ad 10m Roll

Hydrotite is an advanced hydrophilic waterstop designed for sealing construction and cold joints in concrete structures. It is composed of a specially formulated rubber that expands up to 8 times its original volume upon exposure to water, creating an active pressure seal within the joint. This expansion enables Hydrotite to conform to gap variations, ensuring a tight, long-lasting seal that is unaffected by repeated wet-dry cycles.

Its co-extruded design directs expansion across the joint for maximum sealing efficiency, while the delay coating prevents premature expansion during installation. The self-adhesive backing simplifies placement and reduces overall construction time and costs.

Key Features:

• Expands up to 8x its original volume to seal gaps and cracks

• Co-extruded design ensures directional expansion across the joint

• Self-adhesive backing – easy installation, no additional adhesives required

• Delay coating prevents premature swelling during early construction phases

• No welding or special intersections required – simple butt joints

• Compatible with rough surfaces – apply using Leakmaster gun for added adhesion

• No compaction or displacement issues

• Resists degradation through repeated wet and dry cycles

• Non-toxic and non-hazardous – safe for use in potable water applications

Typical Applications:

• Construction and cold joints in water-retaining and water-excluding structures

• Basements, tunnels, retaining walls, water tanks, and culverts

• Pipe penetrations and kicker joints

• Precast segments and in-situ pours
