Category | Usage Scenarios | Characteristics | Advantages | Disadvantages |
---|---|---|---|---|
Standard Grouting Material | General construction, minor repairs | 40 MPa compressive strength (ASTM C39), 0.5% shrinkage | Affordable, widely available | Low strength for heavy loads, shrinkage risks |
High-Strength Grouting (CGM) | Industrial facilities, bridges | ▲▲ 80 MPa (ASTM C39) ▲ (reduced 0.3% shrinkage) | Enhanced load-bearing capacity, improved dimensional stability | Higher cost than standard, requires precise mixing |
No-Shrink Grouting (CGM) | Precision machinery bases, structural repairs | ▲ 0% shrinkage (ASTM C476), 60 MPa strength | Maintains structural integrity, minimizes post-cure defects | Higher cost, limited to specific applications |
High-Strength & No-Shrink (HGM) | Critical infrastructure (tunnels, bridges) | ▲▲▲ 120 MPa (ASTM C39) + 0% shrinkage | Combines maximum strength and zero shrinkage for high-stress environments | Most expensive, requires expert installation |
Ultra-Fine Grouting (HGM-3) | Fine cracks, detailed repairs | ▲ <50μm particles (ISO 13322), 80 MPa | Fills micro-cracks effectively, ideal for precision work | Lower compressive strength compared to coarse mixes |
Waterproof Grouting (CGM) | Basements, swimming pools | ▲▲ IPX7 waterproof (1m immersion for 30min) | Prevents water ingress in wet environments | Not suitable for high-pressure water exposure |
⭐⭐⭐⭐⭐ James Whitaker - Civil Engineer (Bridge Rehabilitation Project)
"We used HGM-4 for grouting critical joints in a deteriorating bridge support structure. The 120 MPa compressive strength and zero shrinkage were non-negotiable for safety compliance—and this delivered perfectly. Even with high-density gravel reinforcement, the mix flowed smoothly into confined zones. Cured in under 25 minutes, allowing us to resume construction faster than anticipated. This isn’t just grout; it’s structural assurance."Purchase Date: April 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Elena Martinez - Home Renovation Specialist
"I’ve repaired countless cracked foundations and uneven slabs in older homes, but shrinkage has always been a headache. I tried CGM-1 on a historic farmhouse floor leveling job last fall. Six months later, not a single crack or settlement. The no-shrink formula really works. It’s also surprisingly easy to mix and pour, even in tight crawl spaces. For residential jobs where precision matters, this is now my go-to."Purchase Date: September 2024 | Usage Period: 8 months
⭐⭐⭐⭐☆ David Lin - Facilities Manager (Urban Hospital Complex)
"We needed a durable, code-compliant grout for re-anchoring heavy medical equipment bases. After consulting the specs, we chose HGM-3 Ultra-Fine Grout for its 80 MPa strength and ability to penetrate narrow gaps. It met ISO 9001 standards and cured without any dimensional shift—critical under MRI rooms. Only reason I’m not giving five stars is the initial learning curve with water ratio calibration. Once we got it right, flawless results."Purchase Date: February 2025 | Usage Period: 4 months
⭐⭐⭐⭐⭐ Tomas Reed - Site Supervisor (Chemical Plant Expansion)
"Harsh environment, aggressive chemical exposure, heavy machinery vibration—this grout had to survive all of it. We went with HGM-4 Pro Model for anchor bolts in reactor foundations. The acid/alkali resistance and rapid 25-minute set time kept our schedule tight. Eight months in, no degradation, no micro-cracking. Worth every penny for high-risk industrial applications. If you’re cutting corners with standard cement, you’re risking structural integrity."Purchase Date: July 2024 | Usage Period: 7 months
⭐⭐⭐⭐☆ Anita Patel - Aquatic Facility Technician
"Used CGM-2 with Gravel for waterproofing a leaking joint in a public swimming pool wall. The material adhered perfectly to damp substrate and formed a seamless, impermeable seal. No more water infiltration after curing. Passed all municipal waterproofing inspections. Only suggestion: include a primer recommendation for highly saturated surfaces. Otherwise, excellent performance in high-moisture environments."Purchase Date: November 2024 | Usage Period: 6 months

Dr. Rebecca Langford - P.E., Structural Materials Consultant
"In over 15 years of forensic analysis on failed grout repairs, shrinkage and inadequate strength are the top culprits. The HGM series’ zero-shrink, high-strength formulation directly addresses these failure modes. For any project where long-term load transfer is critical—especially in seismic zones or aging infrastructure—I now recommend this product line as a best practice."
Dr. Alan Zhou - PhD, Advanced Cementitious Materials Lab
"This CGM/HGM system represents a significant leap in field-ready grouting technology. The controlled particle size in HGM-3, combined with rapid setting and full shrinkage compensation, makes it ideal for precision structural applications. Its compliance with ASTM C401 and ISO 9001 confirms its place in modern, code-driven construction."
