Many injection jobs fail for one reason: the packers don’t seal or align correctly. That leads to leaks, backflow, and epoxy that never travels.
Treat the packer like a valve + connector
It determines whether pressure builds, whether material follows the crack path, and whether the job stays clean.
Answer these 3 questions before you buy
1) What substrate are you working on: poured concrete, block wall, or slab?
2) Is your goal structural repair (epoxy) or water stop (PU)?
3) Do you value jobsite speed/repeatability more than the absolute lowest cost?
The most common installation mistakes (avoid these and you’re ahead)
Dusty holes → poor bite and poor sealing
Wrong angle vs. crack path → material won’t travel
Random spacing → too wide = no continuous fill; too tight = waste and messy flow
Trying to “fix it with more pressure” → the weakest leak point fails first
Fast install, reliable sealing, and easy removal are what contractors pay for.
