Fosroc Conbextra Hf 20kg

Fosroc Conbextra HF is a high-flow, shrinkage-compensated cementitious precision grout, formulated for structural grouting applications requiring excellent flow characteristics, rapid strength gain, and long-term durability. Supplied as a ready-to-use dry powder, it only requires the addition of clean water to produce a free-flowing grout suitable for gap thicknesses up to 125mm. It features dual expansion (plastic and hardened states) and low water demand for maximum performance.

Uses

• Grouting under:

  • Baseplates and structural steel columns

  • Machine foundations and heavy plant

  • Precast concrete elements and anchor bolts

• Suitable for industrial, civil, and infrastructure applications

Key Features and Benefits

• Excellent initial flow and flow retention – ideal for complex and congested areas

• Rapid strength development – supports early plant operation

• High ultimate compressive strength and low permeability – long-lasting durability

• Hydrogen-free gaseous expansion – non-metallic, non-corrosive

• Chloride-free – safe for use with reinforced concrete

• Suitable for both pouring and pumping

• Optimised aggregate grading – minimises bleeding and segregation

• Maximum aggregate size for pumping: 2.5mm
