GEOPUR 2K

Geopur 2K

High-Performance Polyurethane Injection Resin for Water Sealing and Structural Reinforcement

TWO-COMPONENT | FAST-REACTIVE | WATER-ACTIVATED FOAMING RESIN

Geopur 2K is a very fast-reacting, two-component polyurethane injection system designed for demanding applications in water-bearing environments. Engineered to seal, reinforce, and stabilize rock masses, foundations, tunnels, and structures exposed to dynamic water pressure—especially in conditions below 15 °C—this resin forms a high-strength, waterproof foam barrier with excellent chemical stability.

✅ Key Features & Advantages

• ⚡ Rapid Reaction – Sets within seconds; ideal for urgent repairs

• 💧 Water-Activated Foaming – Expands on contact with water to fill gaps and cracks

• 🪨 High Structural Strength – Forms a hard, dense “amber-like” resin with high compressive capacity

• 🌡️ Cold-Climate Performance – Optimized for use in wet, hydrated substrates below 15 °C

• 💪 Excellent Penetration – Fills cracks as small as 0.1 mm

• 🧪 Chemically Stable – Resistant to degradation under pressure and over time

• 🛠️ Easy 1:1 Mixing – Simple two-component application with standard injection systems

• 🚫 Non-ADR Classified – Safe for transport under international regulations

🛠️ Applications

• Sealing and stabilizing cracked, loose, or uplifted rock masses

• Reinforcement of waterlogged tunnels, shafts, and sewers

• Waterproofing diaphragm walls, construction joints, and point leaks

• Repairing foundations exposed to high groundwater levels

• Sealing dams and soil structures against dynamic water inflow

• Deep injection works for long-term subsurface stabilization
