Injection Packers

For Permeation and Compensation Grouting

• To stop water or strengthen the substrate
• Smaller scale grouting, high usage

Examples – Port and Packer Types

• Drilled ports – 9 mm (3/8”) to 100 mm (4”)
• Surface injection – non obtrusive, no concrete damage
• Hammer–in, break-off, removable, or reusable
• Can be inflatable, to hold pressure in sleeve
• Also for void fill (compensation) grouting because substrate is penetrated
• In completed stations with concrete cracks, and in maintenance schedules.
