Their job is to create a tight seal and allow for efficient injection of the chosen grouting material, typically cement or resin, into the target area. Here's a deeper dive into these versatile tools: Types of Injection Grouting Packers: Mechanical Packers: These use a mechanical mechanism, often a screw or a wedge, to expand a rubber sleeve and create a tight seal against the crack walls. They are reusable, cost-effective, and easy to use, making them popular for various applications. Chemical Packers: These rely on a chemical reaction, usually the expansion of a polyurethane foam upon contact with water, to form a seal. They are suitable for wet or underwater applications and offer excellent flexibility for irregular cracks. Hydraulic Packers: These utilize hydraulic pressure to inflate a bladder or membrane, creating a seal against the crack walls. They offer high pressure capabilities and are ideal for large cracks or deep injections.
