Is PU Injection Grouting: The most effective Solution for active leakages?

“Our mission is to deliver advanced, reliable and long-lasting waterproofing solutions through world-class injection technology. With the right combination of quality products, modern machinery and technical expertise, we help build stronger, safer and leak-free structures.”

Active water leakage is one of the most critical challenges in modern construction. Whether it’s basements, tunnels, retaining walls, lift pits, water tanks or concrete joints – once water finds its way inside the structure, it compromises durability, safety and long-term performance.

Traditional waterproofing methods such as surfacecoatings, membranes or integral additives often fail todeliver permanent results when water penetrates deep into cracks, voids and construction joints.

This is where PU Injection Grouting has proven itselfas one of the most efective and reliable solutions for active leakages.

What is PU Injection Grouting?
PU (Polyurethane) Injection Grouting is a process where a liquid PU resin is injected under pressure into cracks, honeycombs, joints and voids. On contact with water, the resin reacts and expands, forming a flexible, durable and waterproof barrier that seals the leakage path from within the structure.

Why PU Injection Works So Effectively

• Stops leakages even under high water pressure
• Penetrates deep into fine cracks and capillaries
• Expands and forms a permanent seal
• Flexible and durable – accommodates structural movement
• Fast, clean and non-destructive application
• Ideal for both dry and active leakages

Applications Across Critical Structures
PU Injection Grouting is widely used in:

The Advantage Over Conventional Methods
Conventional methods treat the surface, while PU Injection treats the source. Instead of hacking, breaking and rebuilding, PU injection offers a targeted, precise and long-lasting solution with minimal structural disturbance, saving both time and cost.

Technology + Machinery = Perfect Results
The success of PU Injection Grouting depends on three key factors the right resin, the right machinery and the right technique. High-pressure injection pumps, quality packers and advanced PU resins. Ensure consistent performance and long-term waterproofing.

The Way Forward
As infrastructure becomes more complex and durability standards rise, the industry needs solutions that are dependable, innovative and future-ready.
PU Injection Grouting is not just a repair technique – it is a modern engineering solution that protects structures, extends life and adds value to every project.
When it comes to active leakages, PU Injection Grouting is not an option -it’s the most efective solution.
