Allied Concrete

What Allied Concrete does

Allied Concrete is a New Zealand ready-mix and engineered concrete manufacturer and supplier, operating as a private subsidiary of HWR Group under the legal entity AML Limited and headquartered in Invercargill. The company produces a broad concrete portfolio across four customer segments — residential, commercial, infrastructure and agricultural — including the CodeMark-certified and BRANZ-appraised SuperSlab and SuperSlab+ engineered foundation systems, the Ecrete and Ecrete Plus low-carbon concrete ranges, Farmcrete agricultural mixes, a suite of decorative finishes (Ready Exposed, Polished, Colour, Glow), and engineered products such as HPFRC, shotcrete, mass pour, waterproof and permeable concrete.

The business is structured around owned Concrete NZ certified plants, an OEM-style licensed partner network (Holcim New Zealand, Higgins Concrete and Kiwi Concrete) that supplies the SuperSlab system across virtually all regions of New Zealand, and the DesignHub engineering service providing free early-stage specifier support followed by paid engineered design. Revenue is generated through per-cubic-metre ready-mix and engineered concrete sales, licensing of the SuperSlab system to other concrete producers, and value-added engineering services.

Distribution combines direct enterprise field sales, an inside-sales phone channel (0800 425 5433), a self-serve digital layer (calculators, My Concrete App, Allie AI chatbot, EPD on-demand), and licensed OEM supply. The company invests in sustainability positioning (Ecrete low-carbon mixes, dual-fuel hydrogen concrete trucks) and is recognised with five consecutive Concrete NZ Gold Status plant awards (2022-2025).

Core offering

Allied Concrete manufactures and supplies ready-mix concrete, engineered concrete mixes and the proprietary SuperSlab/SuperSlab+ raft foundation systems through Concrete NZ certified plants across New Zealand. The company also offers specialised product lines (Ecrete low-carbon, Farmcrete agricultural, decorative Ready series, HPFRC, waterproof and permeable mixes) plus DesignHub engineering support for specifiers, with distribution also delivered via licensed producer networks (Holcim, Higgins, Kiwi Concrete).

Product overview

Allied Concrete (NZ) operates a portfolio of branded concrete products and supporting digital tools rather than a single unified software platform. The portfolio is organised around a core ready-mix concrete supply business plus a family of specialised mixes: the SuperSlab and SuperSlab+ engineered raft foundation systems (the latter enhanced by the QuickSet insulated formwork and QuickEdge edge insulation modules), the Ecrete® and Ecrete® Plus low-carbon concrete ranges, the Farmcrete agricultural mix, the Ready Mix Concrete standard mix, and the decorative Ready Exposed, Ready Polished, Ready Colour and Ready Glow finishes. Supporting these are engineered performance products such as High Performance Fibre Reinforced Concrete (HPFRC), Shotcrete, Mass Pour, Permacore® permeable concrete, Ready Flow, Waterproof Concrete, and High-Strength Engineered Concrete Solutions, along with the Ready Now cold-weather admixture mix and Ready Floor fibre-reinforced slab mix. Allied Concrete wraps the product portfolio with the DesignHub engineering-led design and consenting service, the Allie AI-powered chatbot for 24/7 product guidance, the My Concrete App, a suite of online calculators (Concrete Volume, Ecrete, Fuel Surcharge), and an EPD On-Demand environmental documentation service. Together, branded mixes, foundation systems, engineering services and digital self-service tools form the end-to-end offering for residential, commercial and infrastructure projects across New Zealand.
