The Benefits of GRC and Ex-Situ Production for Interior Fit-Outs in New Zealand

When it comes to interior fit-out projects, architects, interior designers, and fit-out companies in New Zealand face unique challenges—limited space, the need for precision, and the desire to minimise mess and safety risks. Traditional concrete pouring, with its formwork, curing times, and on-site chaos, often isn’t the ideal solution. That’s where Glass Reinforced Concrete (GRC) and its ex situ production methods shine. At Unfound Creations (unfound.co.nz), we specialise in crafting GRC off-site, delivering tailored solutions that elevate interior spaces without the hassle of conventional concrete work.

Why GRC?

GRC is a game-changer for interior fit-outs. This lightweight, high-strength composite—made from cement, sand, water, and alkali-resistant glass fibres—offers unmatched versatility. It’s up to 75% lighter than traditional precast concrete, yet boasts superior tensile and compressive strength, making it perfect for creating sleek, durable features like wall panels, bench-tops, and custom furniture. Its mould-ability allows for intricate designs and textures, giving designers the freedom to craft everything from minimalist surfaces to ornate details—all while maintaining a premium finish that can be coloured or textured to suit any aesthetic.

Unlike steel-reinforced concrete, GRC doesn’t corrode, ensuring longevity even in New Zealand’s variable climate. Plus, its reduced weight means easier handling and installation, cutting down on structural load and transport costs—key considerations for urban projects where every kilogram counts.

The Power of Ex-Situ Production

At Unfound Creations, all our GRC fabrication happens off-site, and that’s a big win for interior fit-outs. Producing GRC ex-situ eliminates the need for on-site pouring, formwork, and the associated mess—think dust, wet concrete spills, and lengthy curing times. This is especially valuable in tight indoor spaces or occupied buildings where disruption must be kept to a minimum. No formwork also means no bulky setups hogging precious floor space, and no safety hazards from wet concrete or heavy equipment.

Off-site production allows us to precision-craft each piece in a controlled environment, ensuring consistent quality and exact specifications. Whether it’s a sculptural wall feature for an Auckland office or bespoke bench-tops for a Wellington café, we deliver ready-to-install components that slot seamlessly into your project. This streamlined approach saves time, reduces labour on-site, and lets you focus on the creative vision rather than managing a construction zone.

Perfect for New Zealand Fit-Outs

For interior designers and architects in New Zealand, GRC’s adaptability is a dream. It can mimic the look of natural stone or timber without the weight or maintenance, making it ideal for heritage-inspired restorations or modern minimalist designs. Fit-out companies benefit from faster installs and less downtime, keeping projects on schedule and within budget. And because we handle everything ex-situ, your site stays clean, safe, and ready for the finishing touches.
