Fosroc Conbextra HF is a high-flow, high-strength, non-shrink cementitious precision grout designed for grouting applications where excellent load transfer, dimensional stability, and durability are required. It is supplied as a ready-to-use dry powder that only requires the addition of clean water before application. The grout provides excellent flow characteristics, allowing it to completely fill gaps beneath base plates, machine foundations, structural steel columns, bridge bearings, and precast concrete elements without segregation or bleeding. Once cured, Conbextra HF develops high early and ultimate compressive strength, ensuring reliable support for heavy static and dynamic loads. It is non-shrink, chloride-free, and suitable for both indoor and outdoor construction projects, making it an ideal choice for industrial, commercial, and infrastructure applications where precision grouting and long-term performance are essential.
