Product Code: 041606

Description

Fosroc Conbextra GP – 25 kg

A ready-to-use, high-flow, non-shrink cementitious grout designed to deliver controlled expansion and fill voids precisely between 10 mm and 100 mm depth. Packaged in a plastic bag for moisture protection, it creates a durable, high-strength fill ideal for structural grouting and anchoring applications

Features

  • Shrinkage-compensated formulation: Gas-expansion system offsets settlement for crack-free, solid fills
  • High ultimate strength & low permeability: Achieves ~65 MPa at 28 days (flowable) with long-term resilience 
  • Versatile consistency: Can be mixed to trowelable or flowable textures using 3.4–4.5 L water per bag
  • Pre-blended & chloride-free: Factory-mixed for consistency and safe around steel reinforcement
  • Chloride-free and non-metallic: Prevents staining or corrosion of embedded components

Applications

  • Under-baseplate grouting in stanchions, machinery bases, and structural columns.
  • Gap filling in precast concrete panels and restricted-access cavities.
  • Anchoring of bolts, tie rods, and reinforcement bars.
  • Precision bedding or dry-packing where flow control is critical.
