RIX Ground Engineering

What RIX Ground Engineering does

RIX Ground Engineering (RGE), established in 2019, is an Australian specialist ground engineering contractor operating as part of The RIX Group. The company delivers an in-house portfolio of ten core services — jet grouting, grout injection, in-situ soil mixing, rigid inclusions, restricted access piling and micropiles, ground anchors, canopy tubes, deep geotechnical investigation, slurry walls, and integrated design-and-construct delivery — to major infrastructure, commercial, mining, ports, and renewable energy projects. Its technology stack centres on a modern, automated fleet of 50+ major plant items, including GPS-controlled batch plants, low-headroom piling rigs capable of working at 2.45m headroom, 61-strand anchoring systems rated to 9,000kN working loads, and heliportable geotechnical rigs capable of 1,000m coring depth. Senior technical leadership averages 25+ years of geotechnical experience, and design work is performed in-house using PLAXIS FEM, WALLAP, RATZ, PIGLET, and AutoCAD.

The business operates a project-based, custom-quoted contracting model: revenue is generated through tendered and direct-enquiry contracts (phone and email intake funnelled to an internal estimating team) with general contractors and project owners. Pricing is bespoke per project, driven by soil conditions, depth, column size, access constraints, and technical complexity, with multi-year contract cadences typical. RGE is headquartered in Kurnell, NSW, and operates regional offices in Brisbane and Perth, supporting nationwide mobilisation across Australia and into New Zealand. Notable end-customers include CPB, John Holland, Ghella, Multiplex, Downer, Georgiou, Gamuda Laing O'Rourke, South 32, and Westfield on infrastructure projects spanning metro stations, light rail, bridges, and fish markets. Certifications include ISO 9001, ISO 14001, ISO 45001, and JAS-ANZ accreditation, which together function as procurement prerequisites for tier-1 infrastructure tenders.

Core offering

RIX Ground Engineering is a specialist ground engineering contractor that delivers in-situ ground improvement and foundation solutions for major infrastructure and building projects across Australia. Core services include jet grouting, grout injection, in-situ soil mixing, rigid inclusions, restricted-access piling and micropiles, ground anchors, canopy tubes, slurry walls, deep geotechnical investigation, and integrated design-and-construct project delivery executed in-house by skilled crews using a modern automated fleet.

Product overview

RIX Ground Engineering (RGE) is a specialist ground engineering contractor providing a comprehensive range of in-situ ground improvement and foundation solutions. The company operates as a unified service portfolio rather than a software platform, offering ten core service offerings: Jet Grouting for high-pressure soil stabilisation; Grout Injection for permeability reduction; In-situ Soil Mixing (wet, dry, mass, shallow and deep techniques); Rigid Inclusions for load-sharing concrete columns; Restricted Access Piling & Micropiles for confined spaces; Ground Anchors with capacities up to 9000kN; Canopy Tubes for tunnelling roof support; Deep Geotechnical Investigation services; Slurry Walls for groundwater containment; and Design & Construct project delivery. These services are delivered in-house by skilled crews using modern automated fleet equipment, with operations spanning multiple locations across Australia.

Products and services

• Jet Grouting An in-situ ground improvement technique using high-pressure grout jets to erode, mix, and stabilise existing soils into soilcrete with strengths between 500 and 10,000 kPa and permeabilities as low as 1×10⁻⁸ to 10⁻⁹ m/s. Delivered for major infrastructure and building projects requiring confined and soft ground stabilisation.
• Grout Injection Ground improvement technique that strengthens weak soil and controls water flow by pumping specialised grouts into soil or rock, including water stop grouting, pressure grouting, and low-impact permeation grouting methods. Used where stabilisation and groundwater control are required.
• In-Situ Soil Mixing Transforms weak or unstable ground into high-strength material through in-situ blending with cementitious binders, delivered via wet, dry, mass, shallow, and deep soil mixing techniques. Uses automated batch plants with real-time GPS control and data logging to achieve ground improvement within hours or days rather than weeks or months.
• Rigid Inclusions High-modulus concrete columns providing cost-effective load-sharing solutions for weak soils, designed using 3D Finite Element Analysis and able to be integrated with stone columns for mixed-modulus applications. Used as a cost-efficient alternative to deep foundations requiring pile caps and grade beams.
• Restricted Access Piling and Micropiles Small-diameter piles (typically 100-300mm, up to 600mm) installed by compact, powerful piling rigs operating in headroom as low as 2m. Provides high load-bearing capacity with resistance to uplift and dynamic forces for restricted access sites including basements, retrofit works, and confined urban projects.
• Ground Anchors Structural elements that transfer loads from structures into the ground to provide stability, including high-capacity permanent ground anchors (SBMA and pressure-grouted systems) with working loads from 5kN to 9,000kN, up to 508mm diameter and 60m deep, supported by stressing jacks from 150kN to 7,500kN.
• Canopy Tubes Self-drilling steel casing pipes providing advanced roof and ground pre-support in tunnelling, creating a reinforced arch above the tunnel face to control deformation, limit water ingress, and provide a safe working environment. Available up to 508mm diameter and 40m in length.
• Deep Geotechnical Investigation Geotechnical investigation services for restricted and remote sites including dams, tunnels, mountain terrain, deserts, and mine sites. Includes soil analysis, vertical and inclined rock coring, and advanced downhole testing (permeability, modulus, in-situ stress, and borehole geophysics), with coring depths up to 1,000 metres via hand-portable to heliportable rigs.
• Slurry Walls Low-permeability underground barriers that block movement of water and contaminants through soil, constructed at depths of 5 to 40 metres using bentonite slurry for trench stabilisation. Capabilities include clamshell grabs, hydraulic cutters, mechanical excavators, and hydromills for depths up to 250m.
• Design and Construct Integrated design and construction contract service managed by RPE-qualified engineers, combining engineering and building services under a single agreed quote. Delivers cost-efficient ground engineering solutions with clear lump sum pricing and single-point accountability.
