Ultra Fine Precision Grout | High Flowability Cementitious Grouting Material for Structural Applications

GT-H80’s ultra-fine micro aggregate achieves superior penetration into tiny gaps down to 0.1mm, perfect for precision CNC machines, optical testers and measuring instruments that demand zero voids under the base. Its 320–350mm high initial fluidity flows evenly by gravity without vibration, while controlled 0.15% micro-expansion eliminates shrinkage gaps to maintain long-term equipment leveling accuracy. With 25MPa one-day compressive strength, precision machinery can be commissioned quickly without long waiting periods..

This precision grout is ideal for pressure injection of 0.1–3mm concrete cracks, small M12 anchor bolts and prefabricated building steel sleeves. It delivers strong permanent adhesion to both concrete and steel, resisting structural movement without debonding. Excellent oil, water and corrosion resistance extends the service life of repaired structures, making it widely used in bridge post-tension ducts, thin-wall component reinforcement and industrial concrete defect restoration.

Simple standardized mixing at a 14%–16% water-to-powder ratio only requires accurate weighing and low-speed high-shear stirring. The homogeneous slurry has no bleeding or segregation, and can be applied via gravity pouring for machine bases or pressure grouting for cracks/ducts. All mixed material must be used within 20–30 minutes, followed by 7 days of moisture curing for full mechanical strength. Factory pre-blended formula ensures consistent batch quality, eliminating on-site proportion errors and reducing construction risks for precision engineering projects..
