Concrete Finishes & Colour Collections

From polished aggregates to artisan hand-trowelled textures, our concrete finishes and colour palettes are designed to elevate architectural spaces. Each finish reflects craftsmanship, material depth, and timeless durability.

Our Signature Concrete Finishes

For architects, builders, and designers seeking refined concrete surfaces, our finishes transform raw concrete into a sophisticated architectural material.

Our Glass Fiber Reinforced Concrete (GFRC) “Off the Form” finish is the epitome of minimalist elegance. By casting against high quality molds, we achieve a smooth, silky surface that retains the raw, honest soul of concrete while offering superior strength and a lighter profile. It is the perfect choice for those seeking clean lines and a contemporary, architectural aesthetic.

Composition

A high-strength matrix of cement, sand, and specialised polymers, internally reinforced with alkali-resistant glass fibres.

PERFORMANCE

This fibre matrix eliminates the need for traditional heavy steel mesh, allowing for a high tensile strength and a slim, elegant 25mm profile.

FINISH (OFF-THE-FORM)

Cast against a smooth substrate to produce a refined, satin surface. It features natural “ghosting” and tonal mottling, providing an authentic architectural aesthetic.

Best For

Integrated ramp basins, large-scale vanity tops, outdoor water troughs as well as seating and a vast range of other uses.

Engineered Cementitious Composite (ECC) represents the pinnacle of concrete technology. Our hand-troweled ECC finish celebrates the “maker’s mark, ” offering a sophisticated, movement-rich surface that is both tactile and incredibly durable. The subtle variegation created by the artisan’s trowel ensures that every piece is a unique, one-of-a-kind statement.

Composition

Often referred to as “bendable concrete, ” this is a high-ductility composite engineered with micro-fibers to provide extreme crack resistance and durability.

Finish (Hand-Troweled)

Unlike the smooth pour of GFRC, ECC is applied by hand, showing the organic “movement” and texture of the artisan’s tool.

Aesthetic

Provides a tactile, “industrial-chic” look with a variegated surface that is unique to every commission.

Best For

High use areas such as kitchen benches, outdoor kitchen and BBQ units, table tops

For a finish that marries timeless luxury with modern durability, our Designer Terrazzo (Polished Aggregate) is unmatched. We meticulously grind and polish the surface to reveal the depth and character of the embedded stone, creating a high-end, reflective finish that adds a sense of permanence and grandeur to any space.

Select from any of our concrete colours and include one or more of our Designer Aggregates to create your own bespoke piece.

Composition

A GFRC, ECC or traditional concrete base embedded with a curated selection of decorative stones which we source from Barossa Quarries.

PROCESS

The surface is mechanically “ground” down using diamond-grit abrasives to expose the crosssection of the internal aggregates.

FINISH

Diamond-polished to a high-honed or semi-gloss luster, offering a timeless, mid-century luxury feel.

Best For

High-traffic flat surfaces and decorative furniture where a multi-dimensional “gemstone” effect is desired.

The Hand Pressed finish is designed for those who appreciate organic texture and depth. This technique creates a characteristic “veining” and mottled appearance reminiscent of natural stone. It offers a rugged yet refined look that brings warmth and a sense of history to modern interiors.

PROCESS

An artisanal technique where the concrete is “pressed” or “packed” into the mold by hand rather than poured.

AESTHETIC

This method creates intentional “voids” and “bugholes” (small surface pits) and a more rugged, distressed texture often associated with raw brutalist architecture.

CHARACTER

It highlights the manual nature of the craft, emphasising the heavy, monolithic soul of the material.

Best For

Feature furniture or sculptural elements where a raw, weathered, or industrial “foundobject” look is required.

Beyond our standard finishes, we offer limitless customization through advanced silicone moulding. We can replicate the intricate, craggy textures of a Rock Face finish or any other natural surface, allowing architects to bridge the gap between the built environment and the natural world with surgical precision.

Select from any of our concrete colours and include one or more of our Designer Aggregates to create your own bespoke piece.

PROCESS

Utilising a custom made silicone mould or hand made mould we can create various surface textures to compliment the clients design

AESTHETIC

The creates a range of surfaces increasing the uniqueness of the custom concrete pieces

CHARACTER

Softening or making a statement to the design process and completed piece.

Best For

The faces of surfaces such as venity facings, table legs, benchtop edges
