VX HydroMaster Hydrophilic Waterstop

Description

VX HydroMaster is a multi-cycle hydrophilic swellable waterstop designed for use in cast in-situ concrete applications.

VX HydroMaster expands upon contact with water to create a pressure-tight seal in concrete construction joints, both horizontal and vertical. Made from a co-extruded combination of expanding hydrophilic material and non-expanding chloroprene rubber, its design directs expansion across the joint for optimal sealing. It changes from dark blue to light blue when expanded, allowing for easy visual inspection on site. VX HydroMaster can shrink back when dry and re-expand with moisture, maintaining functionality through repeated wet-dry cycles.

Advantages:

• Self-adhesive backing simplifies installation and helps lower construction costs
• Co-extruded design ensures expansion is directed across the joint, maximising sealing performance
• Delay coating prevents material from expanding too early
• Resistant to repeated wet-dry cycles without compromising performance
• No on-site welding required, unlike traditional PVC waterstops
• No need for special fittings or intersections — simple butt joints are sufficient
• Can be applied on rough surfaces using a gun-grade waterstop like VX LiquidMaster
• Compatible with traditional PVC waterstops for flexible integration
• No issues with compaction or displacement during installation
• Colour change from dark blue to light blue indicates full expansion for easy visual inspection

Typical Uses:

• Sewerage & water treatment plants
• Pipe penetrations
• Subway stations
• Swimming pools
• Basements
• Reservoirs
• Tunnels
• Pits
