If you have water leaks or cracks in your building, PU injection grouting might be the perfect solution. This simple guide will help you understand everything about this effective waterproofing method.
PU injection grouting is a process where liquid polyurethane is injected into cracks and gaps to stop water leakage. It expands and creates a strong waterproof seal that lasts for years.
By the end of this article, you will know when to use PU injection grouting and why it works so well for fixing building problems.
What Is PU Injection Grouting?
PU stands for Polyurethane. It is a special liquid chemical that expands when it touches water or air.
PU injection grouting is a method where this liquid is pushed into cracks and empty spaces in concrete walls, floors, or foundations. The liquid then grows bigger and fills all the gaps completely.
This process creates a strong waterproof barrier. It stops water from getting through damaged areas in buildings. The method works great for basements, tunnels, and old concrete structures that have leaks.
Common Applications of PU Injection Grouting
PU injection grouting helps solve many building problems. Here are the most common places where people use this method:
For Home Buildings:
- Fixing water leaks in basement walls
- Stopping water from coming through bathroom floors
- Sealing cracks in concrete slabs
- Repairing leaky foundation walls
For Big Structures:
- Waterproofing underground parking areas
- Fixing leaks in bridges and flyovers
- Sealing water problems in tunnels
- Repairing cracks in dams and water tanks
Special Uses:
- Making weak soil stronger under buildings
- Filling empty spaces in old walls
- Stopping water leaks that are still active
- Fixing structures without breaking them
This method works in both dry and wet conditions. It can seal leaks even when water is flowing through the cracks.
Key Benefits of PU Injection Grouting
Why do so many people choose PU injection grouting? Here are the main reasons that make it special:
1. Quick and Easy Process
The whole job can be done in just a few hours. You don’t have to wait for days to see results. The liquid works fast and seals leaks right away.
2. Reaches Every Small Crack
PU liquid is very thin at first. It can go into tiny cracks that you cannot even see. When it expands, it fills every small gap completely.
3. Works with Active Water Leaks
Unlike other methods, PU grouting works even when water is flowing. The chemical reacts with water and becomes stronger. This makes it perfect for emergency repairs.
4. No Breaking or Digging
You don’t need to break walls or dig up floors. Small holes are made for injection. This saves time, money, and keeps your space clean.
5. Lasts for Many Years
Once applied, PU grouting can last 15 to 20 years or more. It stays flexible and doesn’t crack easily. This makes it a smart long term solution.
