High Strength Bearing Grout | Non-Shrink Cementitious Grouting Material for Bridge & Structural Applications

GT-H90 achieves more than 50 MPa compressive strength in just 24 hours, cutting waiting time for demolding and prestress construction to speed up bridge delivery. With over 80 MPa ultimate strength and high elastic modulus, it resists heavy dynamic traffic loads with minimal deformation. Its 320–350mm ultra-high self-leveling fluidity flows naturally to eliminate air voids under bearing plates, while balanced vertical & horizontal micro-expansion removes all shrinkage gaps to guarantee full load transfer between bearings and support pads for precise long-term alignment.

Designed exclusively for high-load bearing installation, GT-H90 fits highway/railway bridge pot & spherical bearings, building seismic isolation supports, heavy industrial equipment bases and large-span stadium steel bearings. It withstands repeated traffic fatigue, freeze-thaw cycles and grease corrosion without delamination, and forms a permanent integrated bond with concrete support pads. Ideal for cast-in-place bridge construction and precast T-beam/box girder yard bearing positioning.

Standard 13%–14% water-to-powder ratio with forced mechanical mixing creates smooth, lump-free slurry; continuous single-side pouring only requires gentle tapping of formwork for air release, no vibrator needed. All mixed material must be consumed within 30 minutes, followed by 7 full days of moisture insulation curing before applying structural loads. Factory pre-blended uniform formula avoids on-site proportion errors, delivering consistent flow, expansion and strength for professional bridge contractors with zero rework risk.
