100 pcs/bag A-20 (1/2" x 5.5") Aluminum Injection Packers - High-Pressure Concrete Repair & Grouting Nozzles

Aluminum Injection Packers are a reliable and high-pressure solution for injecting resins into cracks, joints, or voids in concrete structures and soils. Designed for precision crack injection and leakage control, these packers are essential for concrete repair, foundation reinforcement, and soil stabilization projects where efficiency and ease of handling are key. Constructed with a lightweight aluminum body, they are especially suitable for overhead and vertical structural grouting, reducing fatigue and improving installer control during resin delivery.


Despite their lightweight design, these Aluminum Injection Packers offer superior stability under intense injection pressure, making them a preferred choice for both small-scale concrete restoration and large infrastructure maintenance. They are fully compatible with a wide range of injection materials—including epoxy, polyurethane (PU), and acrylate gels—supporting diverse waterproofing needs in residential, commercial, and industrial environments. Whether you are sealing fissures, lifting slabs, or reinforcing foundations, these packers ensure a consistent flow path for accurate material distribution.


Installation is straightforward and efficient, allowing professionals to work quickly across multiple high-pressure injection points. The corrosion-resistant aluminum construction ensures long-term reliability on the job site and maintains structural integrity during the grouting phase. These injection nozzles are the superior choice for high-volume concrete repair and leak sealing jobs where both high-performance and project budget management are critical to success.
