YURU Injection Packers

Water-stop injection grouting packers are widely used in waterproofing projects, especially in the case of concrete pouring polyurethane and epoxy resin and other chemical grouting materials, and are professional components for high-pressure chemical grouting plugging construction. The principle of water-stop injection grouting packer needles is to use the continuous high pressure generated by the grouting machine to pour the chemical grouting material into the gap inside the concrete, and completely squeeze out the water in the gap, completely fill the gap, and achieve the purpose of water stopping.

Special Features

Features & Benefits

High Pressure Injection Grouting Packers

Efficient water stopping

The water-stopping injection grouting packer can inject chemical slurry into deep and tiny cracks in concrete structures under high pressure to achieve efficient water-stopping effect.

Environmentally friendly materials

The chemical grouting material used is resistant to chemical corrosion, non-toxic and environmentally friendly after curing, and can be permanently waterproof.

Easy construction

Simple operation, fast construction speed and low labor intensity.

Economical and applicable

Construction is not restricted by seasons or weather, and is suitable for various projects, with low comprehensive costs and significant economic benefits.

Safe and durable ‌

The water-stop grouting packer is designed with a check valve to prevent slurry from backflowing and ensure construction safety. ‌

Widely applicable ‌

Applicable to occasions where chemical slurries such as polyurethane and epoxy resin polyurea are poured into concrete to avoid damage to the main structure.

Injection Grouting

injection packers maintenance

1. Find the cracks: clean the base surface, find the cracks, and mark along the cracks with a colored pen or chalk.

2. Drill holes: according to the thickness of the concrete structure, the distance from the crack is about 15 to 35 mm, and cross-drill holes on both sides of the crack direction. The hole spacing should be determined according to the actual situation on site, and the principle is that the slurry can meet at the crack after grouting the two holes. Generally, the hole spacing should be 300 mm at the beginning; the size of the hole diameter should be determined according to the size of the matching water stop needle, and a non-standard 13mm drill bit is used. The hole and the crack section should be 45 to 60 degrees and cross in the 1/3 range of the middle of the bottom plate.

3. Bury the water stop needle: The water stop needle is a matching component, which is a connector for the grouting material to be injected into the crack. When buried, it should be tightened with tools, and the rubber part of the needle and the hole wall should be dry before use, otherwise it is easy to cause slipping during tightening.

What is a water stop injection packer?

‌‌Injection Grouting packer is a tool used for waterproofing, leak repair and structural reinforcement. It mainly injects waterproof materials or chemical grouting materials under high pressure to achieve the purpose of plugging leaks and strengthening structures.

How Can I Get a Quote For The Injection Packer?

Yes, please contact customer service for a reasonable and accurate quotation of the injection packer. Include specific details, including but not limited to quantity and specifications and models.

What is Your MOQ For The Order?

With MOQ of only 100 pieces, you can ensure your order.

What is The Turnaround Time On My Order?

It takes us around 7 to 10 business days. Reach us online for your custom and bulk orders so we can explain the actual turnaround time based on the specific details of your order.

What are the models of water stop grouting packes?

There are many models of high-pressure water-stop injection grouting packers, and common models include A8, A10, A15, B8, B10, etc. The main difference between these models is their diameter and length, which are suitable for different construction needs and scenarios.

What are the types of high pressure water stop injection packers?

There are four types of high-pressure water stop injection packers: copper nozzle, aluminum nozzle, steel nozzle, and plastic nozzle. Choose according to the actual construction scene.

How to use the injection packer?

When the injection packer is used, it is necessary to carry out construction operation with high pressure grouting machine and chemical grouting material. The chemical grouting material enters the leakage part through the injection packer, and the material reacts instantly when it meets water, which can quickly seal the water ‌, strengthen and reinforce.

What is the function of injection packer?

Injection Packers serve as filling valves or ports and connection pieces between the injection equipment and the structure when sealing structures or repairing cracks by injection. They can be used for the injection of various materials.
