Plastic Injection Packers Manufacturer in China
Plastic injection packers are injection ports, which are made of high‑quality plastic materials and are used as a connection point between the injection pump and structural cracks or voids. The packers are used for low-pressure injection, the same as surface injection packers. They are typically installed into drilled holes and allow injection materials such as epoxy, polyurethane, or acrylic resins to penetrate concrete cracks, masonry, or other substrates for concrete repair and waterproofing.
Structurally, this kind of packer consists of a plastic body often combined with a metal grease nipple or fitting (such as a zerk or button head) that allows connection to an injection pump. Some designs, like hammer‑in or bang‑in plastic ports, can be driven into place easily without tightening, which speeds up installation for low‑pressure applications.
We can customize injection packers according to your samples to meet your project requirements.

Plstic Injection Packers Application
Plastic injection packers are commonly used in low-pressure crack injection and sealing projects, where fast installation and cost efficiency are important. They are widely applied in the following specific structural locations:
- Vertical or horizontal cracks in concrete retaining walls, basement interior walls, elevator shaft walls, and underground parking garage walls.
- Floor slabs and industrial concrete floors for crack injection in warehouse floors, factory floors, parking garage slabs, and logistics center floors
- Construction joints and cold joints in concrete walls, slabs, and water-retaining structures, allowing injection materials to seal gaps that cause water seepage.
- Concrete slab voids and small honeycombs, small voids, honeycombs, or surface defects in concrete slabs and structural elements.
- Repairing cracks in precast concrete wall panels, tunnel lining segments, and precast structural elements.

Plastic Injection Packers Advantages
Plastic injection packers offer several practical benefits in grouting and waterproofing applications:
- Lightweight and Cost-Effective
Compared with steel packers, plastic packers are more economical and easier to transport. - Easy and Fast Installation
Hammer-in or push-in designs allow quick installation, reducing labor time during injection work. - Corrosion Resistance
Plastic materials are resistant to moisture and chemicals, which improves durability in damp or underground environments. - Good Compatibility with Injection Materials
Plastic packers work well with various injection materials, including epoxy, polyurethane, and acrylic resins. - Suitable for Large-Scale Crack Injection
Because of their low cost and easy installation, plastic packers are widely used for large-area crack repair projects.

1.Why do plastic packers sometimes fail under pressure, and how can I prevent it?
Plastic packers are generally rated for low‑ to moderate pressures, and using them in high‑pressure applications can lead to deformation or leaks. Choosing the correct packer pressure rating and ensuring it matches your pump output prevents failures.
2.Can I use plastic packers without drilling holes in the surface?
Yes, some plastic surface packers are designed for non‑destructive injection, meaning you can inject through surface applications without deep drilling, which is ideal for horizontal cracks or finishing works.
3. What injection materials are plastic packers compatible with?
Plastic injection packers are suitable for injecting a wide range of grouting materials, including polyurethane resins, acrylate gels, silicate solutions, and epoxy resins. They serve as the connection point between the grouting pump and the crack to ensure controlled material delivery.
