Parchem Hydrotite Cj0725-3k Adh Per Roll ( 10m)

Hydrotite CJ0725-3K ADH is a hydrophilic, self-adhesive waterstop designed to provide superior sealing performance in concrete construction joints. Utilizing advanced hydrophilic technology, Hydrotite expands up to 8 times its original volume upon contact with moisture, forming a positive pressure seal that conforms to joint gap variations and ensures long-lasting water tightness.

The CJ0725-3K profile features a co-extruded design with a delay expansion coating, directing the swell across the joint and preventing premature activation. Its self-adhesive backing streamlines installation, reducing labour and eliminating the need for additional adhesives or welding.

Key Features:

• Expands up to 8x its original size on water contact to seal gaps and joints

• Self-adhesive backing – allows fast and easy installation, reducing costs

• Co-extruded profile – directs expansion across joint for optimal sealing

• Delay coating – prevents premature swelling before concrete placement

• No welding or special intersections required – simple butt joint installation

• Compatible with rough surfaces – can be applied using Leakmaster gun

• Unaffected by repeated wet-dry cycles – maintains performance over time

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

• No compaction or displacement issues

Typical Applications:

• Construction joints in water tanks, basements, retaining walls, culverts, and tunnels

• Cold joints in concrete where long-term water sealing is critical

• Pipe penetrations and precast segment connections

Dimensions:

• Profile: 7mm x 25mm

• Roll length: 10 metres

Installation Notes:
Apply to clean, dry concrete using the integrated adhesive backing. For uneven surfaces, reinforce with Leakmaster adhesive. Protect from moisture before pouring concrete to prevent premature expansion.
