PU Injection Waterproofing is one of our most effective methods for sealing cracks and preventing water leaks. Using high-quality polyurethane (PU) material, we inject this flexible sealant into cracks and joints in concrete structures. This method is ideal for both positive and negative water pressure situations, providing a durable and reliable solution to stop water intrusion and protect your property.
What is PU Injection Waterproofing
PU Injection Waterproofing, also known as Polyurethane Injection Waterproofing, is a technique used to seal and waterproof cracks or joints in concrete structures, such as walls, basements, or foundations. This method is particularly effective for stopping water leaks and preventing future water ingress.
How PU Injection Waterproofing Works:
- Identification of Cracks: The first step involves identifying the cracks or joints where water is penetrating.
- Drilling Holes: Small holes are drilled along the cracks to create entry points for the injection material.
- Injection of PU Resin: A specialized polyurethane resin is injected into the cracks through the drilled holes. The resin expands upon contact with water, filling the voids and cracks completely.
- Curing: The resin then cures, creating a flexible and durable waterproof barrier that stops water from seeping through the cracks.
- Finishing: After the injection, the holes are sealed, and the surface is finished as required.
Benefits of PU Injection Waterproofing:
- Effective Leak Sealing: It stops active water leaks, making it suitable for both repair and preventive applications.
- Durable and Flexible: The cured resin remains flexible, allowing it to accommodate slight movements in the structure without cracking.
- Quick Application: It can be applied relatively quickly, minimizing disruption to the property.
- Cost-Effective: Compared to other waterproofing methods, PU injection is often more affordable and less invasive.
