The 10 mm non-return packers the ACTFLEX PU200, PU300 and PU500 data sheets call for.
Crack Injection 10mm Packers are mechanical injection packers with non-return valves. They are the packer FORSPEC specifies for single-component, high-pressure polyurethane injection with ACTFLEX PU200, PU300 and PU500. Drill 10 mm, tighten with the T-handle wrench, inject.

Correct application makes all the difference.
Insert the packer into a clean, dust-free 10mm hole and leave approximately 20mm proud of the surface for connection and removal. Tighten each packer firmly with the T-handle wrench to seal against injection pressure. Do not over-inject: continue at each packer only until resin extrudes from the crack approximately 100mm either side of the packer, then move to the next packer. Injection into voids of unknown volume can consume large resin quantities, so probe and assess before injecting. Remove all packers after the resin has fully reacted and patch the drill holes flush with a FORSPEC repair mortar. Work to the Safety Data Sheet, PPE and pressure limits of the injection resin and pump being used, and never inject epoxy into an active running leak.
| Packer Type | Mechanical injection packer with non-return valve |
| Packer Diameter | 10 mm |
| Matching Drill Bit | 10 mm |
| Tightening Tool | T-handle wrench (10 mm) |
| Set Out | Approx. 20 mm left proud of the surface for connection and removal |
| Spacing, ACTFLEX PU200, PU300 and PU500 polyurethane injection | Maximum 200 mm along the crack |
| Spacing, ACTFLEX ER300 epoxy injection | 200 to 300 mm along the crack |
| Non-Return Function | Retains the resin under pressure while it cures |
| Removal | Removed after the resin has fully reacted, drill holes then patched flush with FORBUILD 100 or FORCRETE 100 |
| Source note | Specifications are taken from the FORSPEC injection resin Technical Data Sheets. No stand-alone data sheet is published for the packer itself. |

We supply premium waterproofing products backed by expert advice, fast service and real-world experience.
10mm Crack Injection Packers are inserted into pre-drilled holes along a concrete crack to inject hydrophobic polyurethane (PU200/PU300), hydrophilic polyurethane (PU500/Injectswell), or epoxy resin (ER300, Crack Pro 1200) under pressure to seal the crack.
Drill 10mm angled holes at 45 degrees across the crack at 100-150mm spacing, insert the packer, tighten the bolt to expand the rubber sleeve and grip the concrete, then attach the injection gun fitting and inject resin until refusal.
Yes. After injection, cut the packer flush to the concrete surface and patch with epoxy paste. The expanded rubber sleeve cannot be removed cleanly.
Compatible with the full ACTFLEX injection range: PU200, PU300, PU500, Injectswell, Crack Pro 1200PS, ProBond 1100PS, ER300, and Crack Lock E400L. Use the matching gun coupler for the injection pump.
Industry standard is 100-150mm spacing, giving 7-10 packers per metre of crack length. Drill on alternating sides of the crack at 45-degree opposing angles to intersect the crack at depth.
