Question
What are injection packers?
Expert Answer
Injection packers are mechanical valves inserted into holes drilled at 45-degree angles to a crack. They provide a secure connection for the high-pressure injection pump. The packer creates a tight seal in the concrete, ensuring the resin flows *into* the crack rather than leaking back out. They act as one-way valves. After the resin cures, the packers are removed or snapped off, and the holes are patched.
