High-Strength Ultra-flow Grout

High-Strength Ultra-flow Grout

JTB High-Strength Ultra-Flow Grout is formulated with high-strength materials as aggregates and cement as a binder, supplemented with high fluidity, micro-expansion and anti-segregation materials.​

Product Features

• Early & high strength
• Slight expansion
• High flowability
• Non-shrink
• High bonding strength
• High durability

Applications Scenarios

• Repair of aged or damaged structures
• Reinforcement of foundations, fill layers, reinforcing concealed structures, and installing vibration-damping and sound-insulating layers.

Construction Craft

• Surface preparation: Before construction, remove any loose dust, grease, and debris from the substrate surface to ensure it is clean, sound, and level. Thoroughly moisten the substrate, but avoid any standing water.
• Mixing Ratio and Procedure: Weigh out Jintongbao High-Strength Ultra-Flow Grout and add water at 12% of its weight. Mix for approximately 3 minutes. Mechanical blending is recommended to achieve a thorough blend, mixing until uniform.
• Application: Pour the Jintongbao High-Strength Ultra-Flow Grout from one side. Use a bamboo rod to poke and compact the material if necessary. After initial setting, cure by covering with plastic film or by water spraying.

Packaging and Storage
