Adhesive Packer

Product Description

The Adhesive Packer is a surface-mounted injection port made of a plastic body fitted with an enclosed steel conical M8 nipple that screws into the body’s internal thread. It is designed to be glued directly to the component surface over a crack — no drilling required.

This makes it the right tool for substrates where drilling would compromise the structure or the visible finish: thin shells and panels, pre-stressed concrete elements, hollow blocks where a drill bit would simply punch through into the cavity, heritage stone or brickwork, and any surface where the final appearance must remain unmarked.

The 50 mm adhesive base distributes injection pressure over a wide bonding area, while the M8 thread accepts standard European-market injection couplings and check valves.

Characteristics and Advantages

• No drilling required — bonds directly to the surface with two-component epoxy paste, ideal for substrates that cannot or should not be drilled
• Wide 50 mm adhesive footprint — distributes injection pressure across a large bonded area, preventing the packer from “jumping off” under pressure
• M8 thread + steel conical nipple — universal European-standard connection; works with every injection gun and check valve in the M-thread family
• Low 26 mm profile — easy to skim, plaster, or paint over after the resin has cured and the packer has been removed
• Plastic body + steel nipple — combines the chemical resistance of plastic with the mechanical strength of steel where it matters (the injection connection)
• Compatible with all common injection resins — polyurethane, epoxy, acrylic gels, and silicone emulsions for horizontal damp-proof course (DPC) work

Application Instructions

1. Mark the crack and clean a 50–80 mm wide strip along its full length with a wire brush. The bond strength of the adhesive packer depends on a clean, dust-free substrate.

2. Mix the two-component epoxy paste (1:1 by volume) until uniform grey. Avoid trapping air bubbles.

3. Apply a thick bead of epoxy paste to the underside of the adhesive packer, then press the packer onto the substrate directly over the crack. Make sure the central injection hole in the packer base is aligned with the crack itself — the resin flows out through this hole into the crack.

4. Smooth the surrounding paste to form a 50 mm sealing strip across the crack between packers. Repeat for every packer along the crack length, with packer-to-packer spacing typically 100–250 mm depending on crack width.

5. Wait for the epoxy paste to fully cure as specified on the paste data sheet (typically 4–24 hours depending on ambient temperature). Curing must be complete before any injection pressure is applied.

6. Connect the injection gun or pump via the M8 conical nipple. Inject the resin at the pressure specified by the resin manufacturer until resin returns at the adjacent packer.

7. Close the adjacent packer’s check valve and move on along the crack until the full length is filled.

8. Allow the resin to cure as specified on the resin data sheet.

9. Remove the packers by gently grinding off the heads and the surrounding adhesive band. The substrate can then be skimmed or plastered for an invisible finish.

Applications

• Cracks in thin substrates — Concrete shells, panels, and slim walls where drilling would breach the substrate
• Hollow brick and block walls — Where a drill hole would punch straight through into the cavity
• Heritage and decorative surfaces — Stonework, exposed brick, decorative concrete that must be repaired without leaving drill marks
• Tiled or rendered surfaces — Where the drill location cannot be reliably aligned with the underlying crack
• Pre-stressed and post-tensioned concrete — Where drilling risks damaging tendons or reinforcement
• Polished, exposed, or finished concrete floors — Where surface drilling is visually unacceptable
