CBGM-380 Precision Grout for Tight Clearances
CBGM-380 Precision Grout for Tight Clearances is a high-performance, ultra-fluid, non-shrink cementitious grout specially engineered for filling narrow gaps and confined spaces with precision. It offers excellent flowability, rapid early strength, and zero bleeding—making it ideal for equipment base plates, anchor bolts, precast joints, and structural void filling where tight tolerances are required. Key Features: Ultra-Flowing: Designed for narrow or complex geometries with flow cone time ≤35s Tight Clearance Grouting: Easily penetrates confined areas without segregation or blockage High Early Strength: ≥15 MPa at 1 day, ≥30 MPa at 3 days, ≥50 MPa at 28 days Non-Shrink & Expanding: Controlled vertical expansion 0.1–3.5% to ensure full contact and long-term stability Zero Bleeding: Maintains grout integrity and uniformity Corrosion Resistance: Chloride ion content <0.1%; safe for use around steel reinforcements

Product Overview
CBGM-380 is a premium-grade, bleed-resistant precision grout designed for use in tight clearance grouting and high-tolerance structural placements. Its ultra-smooth, pumpable consistency ensures effortless placement into narrow voids and under base plates without segregation or settlement. This cementitious non-shrink grout delivers high early compressive strength while maintaining zero bleed and excellent dimensional stability.
Engineered for demanding industrial and infrastructure projects, CBGM-380 grout for tight clearances meets the needs of contractors and engineers requiring accuracy, efficiency, and long-term performance—especially in complex anchoring, rebar embedding, or machine base installations.
Applications
Precision grouting for machinery base plates
Filling narrow voids under structural steel and precast panels
Anchor bolt grouting in dense configurations
Repair and strengthening of concrete in limited access areas
Construction process
Clean substrate thoroughly; remove oil, dust, loose materials.
Saturate substrate surface with clean water (SSD), but no standing water.
Mix using high-shear mixer for 3 minutes until lump-free.
Pour or pump grout into forms continuously; do not vibrate.
Protect exposed surfaces and cure per standard guidelines.
