Hybrid Injection System for High-Pressure Waterproofing
The IC 325CCP combines cement and 2K polyurethane injection in one compact system. Reduce material costs, eliminate re-injections, and maintain progress in pressurized water zones.
Reduce Material Consumption
Smart CCP technology combines cement and PU only where needed. Significantly reduce resin consumption compared to pure polyurethane injection while maintaining sealing quality.
Eliminate Downtime
Fast-reacting hybrid mix prevents washout even at high flow rates. Automated real-time control ensures consistent quality—no guesswork, no delays.
Compact Design
40 kg, 2.1m length. Designed for TBM integration and confined spaces. Lower transport costs, faster mobilization.
Real-Time Process Control
Complete transparency through automated log data monitoring. Track every injection parameter—pressure, mixing ratio, volume—with full traceability for quality assurance and project documentation.
Reduce Re-Injection Cycles
High reactivity and precise component coordination enable effective sealing in the first injection pass. Minimize additional work cycles and project delays.
Flexible Mixing Ratios
Infinitely variable control adapts to changing geological conditions on-site. Switch between pure cement, pure PU, or any hybrid combination without equipment changes.
Cement + Polyurethane = Precision Under Pressure
The IC 325CCP integrates WIWA K2 high-pressure pumps with RASCOR static mixing technology. Adjust mixing ratios in real-time based on geological conditions–pure cement, pure PU, or any combination in between.

Proven Performance in Critical Applications
Tunnel Construction
High water pressure zones where conventional cement grouting fails. CCP provides immediate sealing and structural stability.
Mining & Shaft Sinking
Confined spaces with unstable rock formations. Compact design enables installation where larger systems cannot operate.
Dam & Hydraulic Engineering
Porous formations with high flow velocity. Hybrid mix penetrates deep and resists washout.
Ground Stabilization
Variable soil conditions requiring flexible material response. Adjust cement-to-PU ratio for each geological layer.

Why Choose the IC 325CCP?
| Feature | IC 325CCP | Other Injection Systems |
| Injection flexibility | 3 injection modes in one system (pure cement, pure PU, or hybrid CCP) | Only cement or PU separately, no hybrid option |
| Compact design | 2.1m length, 840 kg – optimized for confined spaces and TBM/SBM integration | Larger systems, less suitable for confined spaces |
| Process control | Automated with real-time log data (pressure, mixing ratio, volume) | Often manual with less data transparency |
| Mixing technology | RASCOR static mixer ensures homogeneous PU mixing | Varies by system |
| On-site adaptability | Freely adjustable mixing ratios based on geological conditions | Limited flexibility, often requires equipment changes |
| Environmental impact | Reduced CO₂ footprint through hybrid cement-PU mix | Cement-heavy systems have higher CO₂ footprint |
Frequently Asked Questions
Can I use both cement and polyurethane at the same time?
Yes. The IC 325CCP can inject pure cement, pure polyurethane, or a combination of both in a single pass. You can adjust the mixture on-site based on your project needs.
Will this system fit in my tunnel boring machine?
Yes. The IC 325CCP is specifically designed for tight spaces and integration into TBMs, SBMs, and other confined work areas. It measures 2.1m in length and weighs 840 kg.
How long does delivery take?
Standard delivery time is 8-10 weeks from order confirmation.
Can I adjust settings during operation?
Yes. All injection parameters—including pressure, mixing ratios, and flow rates—can be adjusted in real-time through an intuitive control interface.
What is the maximum water pressure this system can handle?
The IC 325CCP operates at pressures up to 100 bar, making it suitable for high-pressure water zones in demanding tunnel and mining projects.
Do I need special materials or can I use standard cement?
The system processes standard cement suspensions with grain sizes up to 5mm. You'll need compatible 2-component polyurethane materials for the hybrid or pure PU injection modes.
