Ready-Mix Grouts for Civil Infrastructure

Optimised Grouting for Structural Efficiency and Project Speed

Master Builders Solutions offers an advanced ready-mix grout systems that deliver high-performance, pre-blended cementitious solutions for critical infrastructure applications. Designed to streamline installation, reduce site risks, and ensure long-term durability, our MasterFlux RMX range is engineered to meet the needs of modern civil construction projects.

Key Characteristics of RMX Grouts

High Strength: Achieves compressive strengths up to 80 MPa, suitable for heavy-duty structural applications.

Volumetric Stability: Non-shrink performance as per ASTM C1090 to eliminate settlement and cracking.

High Flowability: Optimised for pumpability and deep pours, with slump/flow values exceeding 550 mm.

Low Thermal Resistivity: Specialised mixes available to minimise exothermic heat and enhance heat dissipation.

Zero Bleed and Segregation: Ensures full encapsulation, particularly in critical areas such as post-tension cable ducts.

Environmentally Responsible: Delivered in agitators, reducing dust emissions, packaging waste, and overall carbon footprint.

Key Applications

Post-Tension Cable Grouting

• Provides complete void-free encapsulation for ducts, improving long-term cable durability.

Pile and Annulus Grouting

• High-flow, stable grouts ensure uniform placement with no on-site mixing required.

Void Filling and Rock Bolting

• Engineered for precision and strength in backfill, anchoring, and stabilisation applications.

Structural Repairs and Foundations

• Deep-pour solutions suitable for columns, slabs, footings, and large-scale repairs.

Thermal Management in Electrical Infrastructure

• Low TR value grouts support HV cable encasement with improved heat dissipation for higher load performance.

Project Support and Custom Mix Designs

With local manufacturing across Australia and New Zealand, our technical team can tailor bespoke mix designs to meet unique project specifications, including fast-set, extended work time, and underwater grouting options. Every batch is QC-tested for consistency and reliability under diverse conditions.

For large-scale infrastructure grouting projects where time, performance, and safety matter, our MasterFlux RMX range is the reliable, engineered solution. Contact our team for tailored advice and product recommendations for your next project.
