• Polyurethane Grout Injections are a highly effective waterproofing method used to stop active water leaks in concrete structures like basement walls, foundations, tunnels, retaining walls, and more.

🔧 How It Works:

• A liquid polyurethane resin is injected directly into cracks or voids in concrete.
• When it comes into contact with water, the polyurethane expands (foams) and fills the space.
• This forms a flexible, waterproof seal that blocks further water penetration.
• The material adapts to small structural movements without cracking or breaking.

💡 Where It's Used:

• Foundation wall cracks
• Basement leaks
• Underground water tanks
• Tunnels and parking garages
• Water-retaining structures
• Concrete joints with leakage

✅ Benefits of Polyurethane Injections:

• Stops water instantly, even under pressure
• Expands to fill tiny cracks and large voids
• Fast and non-invasive process
• Long-lasting, waterproof, and flexible seal
• Suitable for both wet and dry cracks
• Minimal disruption — no major demolition needed

• A waterproof liquid membrane is a seamless, rubber-like coating applied to the exterior of foundation walls to protect against water penetration, soil moisture, and groundwater pressure.
• Once applied, the liquid cures to form a continuous waterproof barrier that stretches and moves with the building — perfect for protecting foundations from leaks and long-term moisture damage.

• At KAA, we apply liquid membrane systems with care and precision to ensure your foundation stays dry for years to come.
