Understanding PU Resin Injection
Polyurethane (PU) resin injection is a common method used to stop active water leaks in concrete structures. PU resin is a type of polymer that is widely used in construction and engineering due to its excellent mechanical properties, such as high strength, durability, and resistance to chemicals and weathering. PU resin injection involves injecting a liquid resin into the cracks, voids, or joints of a concrete structure to form a solid and watertight seal.
PU resin injection systems are designed to be fast, efficient, and cost-effective. They can be used to repair a wide range of concrete structures, including buildings, bridges, tunnels, dams, and reservoirs. PU resin injection is particularly useful for structures that are difficult to access or require a non-invasive repair method.
Polyurethane resin injection can be done in two ways: low-pressure injection and high-pressure injection. Low-pressure injection involves injecting the resin into the cracks or voids using a hand pump or a pressure pot. High-pressure injection involves using a mechanical pump to inject the resin at a higher pressure, which allows the resin to penetrate deeper into the cracks or voids.
PU resin injection has several advantages over other repair methods. Firstly, it is a non-invasive method that does not require excavation or demolition of the structure. Secondly, it is a fast and efficient method that can be completed in a short amount of time. Thirdly, it is a cost-effective method that can save time and money compared to other repair methods. Finally, PU resin injection provides a permanent and watertight seal that can last for many years.
In summary, PU resin injection is a highly effective method for stopping active water leaks in concrete structures. It is a fast, efficient, and cost-effective method that can provide a permanent and watertight seal. PU resin injection systems are widely used in the construction and engineering industry due to their excellent mechanical properties and versatility.
How PU Resin Injection Works
Polyurethane resin injection is a popular method for stopping active water leaks in concrete structures. The process involves injecting a low viscosity polyurethane resin into cracks, holes, joints, and voids to seal and repair them. The resin reacts with water to expand and create a waterproof seal that prevents further water ingress.
The injection process starts with identifying the location of the water leakage. Once identified, the area is prepared by cleaning and drying the surface. Then, the injection ports are installed at regular intervals along the crack or void. The polyurethane resin is then injected under high pressure using a pump. The resin flows into the crack or void, filling it entirely and creating a waterproof seal.
One of the advantages of using polyurethane resin injection is its low viscosity. The low viscosity allows the resin to penetrate deep into the concrete structure, ensuring a durable and long-lasting seal. Additionally, the polyurethane resin can withstand movement and expansive reactions, making it an ideal solution for sealing leaking cracks and joints in concrete structures.
Overall, polyurethane resin injection is an effective water leakage treatment for concrete structures. It is a versatile solution that can be used against high or low water-bearing joints and cracks in concrete structures and below-ground construction.

When concrete structures are not waterproofed, they are vulnerable to water ingress, which can cause a range of problems such as structural damage, corrosion of steel reinforcement, and mold growth.
PU resin injection is a cost-effective and efficient method for repairing active water leaks in concrete structures. It involves injecting a liquid PU resin into the concrete structure, which then expands and solidifies to form a waterproof barrier. This method is particularly effective for repairing cracks, joints, and other defects that allow water to penetrate the concrete.

This means that repairs can be carried out quickly and with minimal disruption to building occupants. In addition, the use of PU resin injection can improve the overall quality of the construction work by addressing water leakage issues that may have been caused by poor workmanship or construction problems.
PU resin injection can also improve the quality of the concrete by reducing its permeability. When concrete is permeable, it allows water and other liquids to penetrate the surface, which can cause damage over time. By injecting PU resin into the concrete, the permeability of the concrete can be reduced, which can improve its durability and longevity.
In summary, PU resin injection is a highly effective method for repairing active water leaks in concrete structures. It can address construction quality and workmanship issues related to water leakage, improve the quality of the concrete, and reduce the need for major demolition or reconstruction work.
