What Can GRC / GFRC Be Used For?

When architects or designers first encounter GRC (Glass Reinforced Concrete), also known as GFRC (Glass Fibre Reinforced Concrete), the most common question is: what can it actually be used for?

The answer is — almost anything.

This versatile composite combines cement, fine aggregate, water, and alkali-resistant glass fibres to create a material that’s lightweight yet strong, sculptural yet durable. It can be moulded, textured, or coloured to achieve forms and finishes that traditional precast or poured concrete can’t easily replicate.

Here’s a look at some of the key applications where GRC/GFRC is being used around the world.

1. Architectural Facades and Cladding

GRC’s most common use is in lightweight cladding panels. It offers the strength and surface quality of concrete at a fraction of the weight — allowing for bold, expressive façades that remain practical to install and maintain.

It can mimic natural stone, cast intricate relief patterns, or achieve smooth minimalist finishes. The result is durable, weather-resistant, and non-combustible — making it ideal for both new builds and façade restorations.

2. Sculptural and Decorative Elements

Because it can capture fine detail, GRC is often used for architectural ornamentation, public art, and custom sculptural features.

Columns, cornices, finials, balustrades, and even large-scale artworks can be fabricated in GRC, offering the appearance of carved stone with a fraction of the weight and cost.

Many international fabricators showcase entire portfolios of GRC domes, fountains, columns, and custom sculptures — proof of the material’s flexibility in form and finish.

3. Domes, Roof Features, and Overlays

GRC is also used structurally as roof cladding or overlay systems. Lightweight panels can form part of domes, curved roofs, and other decorative roof structures.

In some projects, GRC tiles are used as decorative overlays above watertight roofing systems, offering the look of traditional clay or stone tiles without the weight burden on the structure below.

4. Interior Applications

Designers are increasingly bringing GRC indoors. Its thin section and customisable finish make it perfect for feature walls, reception counters, fireplace surrounds, and sculptural ceilings.

When finished in polished, sandblasted, or pigmented surfaces, it becomes a material that feels natural and tactile — bridging the gap between architecture and art.

5. Landscape and Urban Design

Outdoors, GRC finds use in planters, benches, paving elements, and decorative screens. It’s durable enough to handle the environment, yet light enough to be installed without heavy lifting equipment.

For civic spaces and commercial environments, GRC allows designers to create cohesive, sculptural landscapes that complement built architecture.

Why Architects Are Turning to GRC

Beyond its design flexibility, GRC offers several practical benefits:

• Lightweight: typically 75% lighter than precast concrete.

• Ex-situ Casting: off-site casting for a clean and fast fit-out.

• Durable: resistant to cracking, impact, and weathering.

• Versatile finishes: from stone textures to metallic coatings.

• Sustainable: uses less raw material and energy than traditional concrete.

• Customisable: each piece can be uniquely shaped or patterned.

Think Beyond Concrete

GRC / GFRC isn’t just a building material — it’s a creative medium.

It invites architects, designers, and artists to explore form, texture, and light in new ways.

Whether for façades, sculpture, or feature interiors, GRC bridges the gap between structural integrity and design freedom.
