Crack injection ports
Surface-mounted plastic injection ports and packers — technical reference for concrete cracking in Australian remedial building practice. Covers system selection, product comparisons, and brand equivalents.
What is crack injection ports?
Crack injection ports are small plastic fittings installed along the length of a concrete crack at regular intervals to provide controlled entry points for injection resins and grouts. They can be surface-mounted with structural adhesive (adhesive-bonded ports) or drilled and mechanically fixed into the crack (drill-in ports), and connect via Schrader or Luer fittings to injection pumps or cartridge guns. Correctly spaced ports — typically 150–300 mm centres depending on crack width, depth, and resin viscosity — are critical to ensuring the void is completely filled without uninjected zones remaining. After injection is complete, all ports are removed or broken off, holes are plugged with repair mortar, and the surface is restored. A consumable item — part of every crack injection system regardless of the resin type used.

System Description
Bond to crack surface with epoxy paste. Space at 1x crack depth intervals. Remove after injection and cure.
Technical Properties
- Low unit cost — essential consumable component of any crack injection system
- Quick to install with surface-mount adhesive or drill-in methods
Limitations
- Must be correctly spaced (typically 150–300 mm) to ensure full resin penetration
- Surface-mount types can detach if substrate is not properly cleaned before bonding
