Glass Fiber Reinforced Concrete: Pros and Cons for Commercial Use

What Is GFRC and How Does It Work?

Glass Fiber Reinforced Concrete (GFRC) is a specialized type of concrete that incorporates alkali-resistant glass fibres into a cementitious matrix. These fibres act as primary reinforcement, enhancing tensile and flexural strength performance. Unlike traditional concrete, which relies on steel rebar and is primarily used for load-bearing applications, GFRC is optimized for non-structural architectural use, mainly in facade cladding, interior panels, and complex forms.

View Details

GFRC stands apart from traditional concrete because it combines strength with a lightweight composition. This makes it especially valuable in commercial construction, where aesthetic appeal and long-term durability are essential. Products like Sound-Rite's Rieder GFRC panels illustrate this innovation, delivering high-end architectural finishes tailored to commercial environments.

Is GFRC Stronger Than Concrete?

The strength of any concrete product depends on how well it resists forces such as tension, compression, and bending. While traditional concrete is known for its compressive strength, GFRC excels in other critical areas, making it a more versatile material in architectural design.

Tensile Strength

Conventional concrete has inherently poor tensile strength, so it's often paired with steel reinforcement. GFRC changes that equation. The mixed's distributed glass fibres significantly improve tensile performance, helping the material resist pulling forces and reducing the risk of cracking or fracturing under stress.

Flexural Strength

GFRC offers high flexural strength, which enables it to withstand bending and deflection. This is a key reason why it's favoured in facade systems and thin-wall panels. The material's ability to flex without breaking allows various architectural designs, from sharp angles to curved, organic forms.

Compressive Strength

While GFRC can match or exceed the compressive strength of traditional concrete, often reaching up to 10,000 psi, it is not intended to be used as a load-bearing structural material. Instead, it's best suited for architectural applications where reduced weight and enhanced durability are desired.

Is Fiberglass in Concrete as Good as Rebar?

Depending on the application, fibreglass and rebar serve different purposes but can enhance the performance of concrete.

In traditional structural concrete, rebar reinforces significant, load-bearing components such as columns and beams. It is heavy, corrosion-prone, and labour-intensive to install. GFRC, by contrast, incorporates fibreglass directly into the mix. This results in multidirectional reinforcement, offering improved performance in panels and surfaces subjected to bending, thermal cycling, and environmental exposure.

Compared to steel-reinforced concrete, GFRC offers:

• Better resistance to cracking and shrinkage

• Improved flexibility and resilience under thermal and mechanical stress

• Enhanced durability in outdoor and moisture-exposed environments

Unlike rebar, glass fibres don't corrode over time, making GFRC a longer-lasting material for exposed or decorative applications.

Advantages of Fiber Reinforced Concrete

GFRC is particularly well-suited for commercial projects that demand both performance and aesthetics. Below are the most compelling benefits.

Lightweight with High Strength

GFRC is significantly lighter than precast concrete, often by up to 75%. This reduces the structural load on buildings and simplifies transport and installation. Its high strength-to-weight ratio makes it ideal for large-scale facade systems and retrofit projects.

Wide Range of Aesthetic Finishes

With advanced moulding capabilities and integral pigmentation, GFRC can be produced in a variety of textures and colours. From natural stone looks to smooth modern finishes, GFRC panels like those from Sound-Rite's Rieder line offer designers exceptional visual flexibility while maintaining technical integrity.

Enhanced Crack Resistance

The glass fibres control micro-cracking, minimizing structural weaknesses and improving the long-term appearance of panels. This feature is especially beneficial in climates with fluctuating temperatures or moisture levels.

Because it is lighter, GFRC requires less energy for transportation and installation. Additionally, its durability means fewer replacements and less material waste over time. Some products also incorporate recycled content, aligning with LEED and green building standards.

Faster Installation with Prefabrication Options

GFRC panels are commonly produced off-site in controlled environments, which enhances quality control and enables rapid and efficient installation. This minimizes construction delays and labour costs, a critical consideration in commercial projects.

Disadvantages of Glass Fiber Reinforced Concrete

Despite its numerous advantages, GFRC has some limitations that must be considered during the design and planning stages.

Higher Upfront Cost

GFRC is generally more expensive than traditional concrete on a per-square-foot basis. However, the savings in installation time, labour, and lifecycle maintenance often make it a cost-effective investment over the life of a project.

Skilled Labour Required

The production and application of GFRC require specialized knowledge. Proper mixing, casting, and curing are crucial to ensuring optimal performance, making quality control a paramount consideration. Working with experienced manufacturers—such as Sound-Rite—helps mitigate these risks.

Not Suitable for Load-Bearing Structures

GFRC is engineered for architectural and aesthetic functions. It should not be used where compressive structural loads are required, such as in foundational elements or support columns.

Quality Can Vary Without Consistency

Inconsistent fibre distribution or improper curing can result in weak spots or visual defects. This is why partnering with a reputable supplier is crucial for achieving reliable results.

Use Cases in Commercial Applications

GFRC's unique blend of strength, lightness, and design versatility makes it especially valuable in the commercial sector.

Introduction

Market trends indicate a surge in the adoption of Glass Fiber Reinforced Concrete (GFRC), driven by advancements in material technology, stricter building regulations, and the need for energy-efficient building structures. As modern construction is actively looking for innovative materials that provide both structural reliability and aesthetic appeal, fiberglass-reinforced concrete has become one such material that conveniently combines these two critical aspects.

DEFINITION: What is GFRC?

Glass fiber-reinforced concrete (GFRC) is a composite of alkali-resistant (AR) glass fibers embedded in a cementitious mixture, which could be a paste, mortar, or concrete, possibly with additives and admixtures added for improved processability, properties, or both.

While the idea is comparatively novel, the technology is not: its properties have been thoroughly researched — arguably as much as, if not more than, those of many other materials. In fact, GFRC composites have been in successful commercial use for over 60 years. This proves that, when designed and manufactured according to recommended practices, they can deliver reliable performance and longevity.

In this article, we’ll explore all the essential aspects of Glass Fiber Reinforced Concrete — from its unique properties and structural advantages to its growing role in modern construction, featuring its properties, benefits in construction, and the ways it has been used in real-life projects worldwide.

Industry Trends Driving GFRC Growth

Urbanization and high-density development Sustainability and Green Building Initiatives Shift towards off-site and modular construction Demand for complex architectural designs Regulatory push for structural performance and safety The challenge of resisting climate, seismic, and corrosion impacts Energy-efficient and smart buildings Robotic fabrication, 3D printing, and AI make GFRC more efficient Cost-effective alternative to traditional materials

Advantages of Using GFRC in Modern Construction: Why It Is An Ideal Solution for Facade Systems

GFRC is considered an advanced solution for facade systems and a preferred choice for numerous architects and designers worldwide. Let’s explore its key advantages below.

Lightweight Efficiency

One of the major benefits of GFRC is its lightweight nature, which is up to 75% lighter than equivalent precast concrete. By replacing part of the concrete matrix with glass fibers, GFRC reduces structural load — making it ideal for facades, cladding panels, and roofs.

Material Weight Comparison: GFRC’s Lightweight Advantage Over Traditional Materials

Hence, its lighter weight brings numerous additional benefits: lower transportation costs, faster installation, and the ability to be installed even in hard-to-reach areas using smaller, more affordable cranes. Thanks to its lightweight properties, GFRC is often used in rehabilitation and retrofit projects. Using GFRC for recladding reduces the load on existing structures.

Example:

The Marriott Hotel in San Francisco, by installing 340,000 ft² (31,587 m²) of GFRC panels, reduced structural steel requirements by 330,700 lb (150 tonnes) compared to precast concrete cladding.

Strength and Resilience

Despite its lightweight properties, GFRC is incredibly strong — providing high tensile strength, crack resistance, and impact resistance.

GFRC is capable of withstanding harsh weather conditions and mechanical stress without compromising its structural integrity. Its resilience makes it an ideal choice for facades, cladding, and high-traffic areas, particularly in regions with extreme climate variations, heavy wind loads, or seismic risks.

Example:

The National Museum of Qatar project utilized GFRC facade panels due to their ability to withstand extreme weather conditions, including extreme heat and sandstorms, which are typical of the Qatari climate.

Not only did the material provide the required durability, but it also enabled the creation of complex architectural forms that aligned with the architect’s aesthetic vision.

Hurricane-Proof Safety

GFRC panels are strong enough to provide hurricane-proof safety. In doing so, they can be specifically designed to meet up to the Class 4 standard required for critical structures such as hospitals and emergency shelters.

Example:

In , a Miami-Dade County building project used GFRC cladding to meet strict hurricane resistance standards.

The GFRC panels for this project were engineered to pass the Class 2 impact resistance requirement, applicable to most building types in this area. To meet this standard, the panels successfully underwent rigorous testing, where a 2×4 wood missile of a known weight was fired at a speed of 50 ft/s (15.25 m/s) twice on each panel.

Unparalleled Fire Resistance

GFRC is non-combustible and fire-resistant. This resistance is so strong that it can even protect the materials behind it in case of fire. This makes GRC a highly advantageous material for constructions that may be at a greater risk of fire.

Example:

Based on meticulous testing by DSA, GFRC panels have been proven to achieve a 2-hour fire resistance rating when tested in accordance with ASTM E119.

This means GFRC panels can achieve a 2-hour fire resistance rating when used in a wall panels system that includes:

• ½-inch (13 mm) GFRC panel as exterior cladding;
• Steel stud frame for support;
• 5 inches (127 mm) of fiberglass insulation;
• ⅝-inch (15 mm) fire-rated gypsum board on the interior.

Support for Intricate, Versatile Designs

One of GFRC’s most remarkable qualities is its ability to be manufactured in thin sections — often as thin as ½ inch (12 mm) — without compromising strength. This enables near-limitless design flexibility, allowing architects to create intricate, detailed features without concerns about fragility.

GFRC can also be molded into complex shapes, ideal for unique, highly customized designs. Architects and designers can achieve curved, sculpted, or textured surfaces that would be difficult or impossible with traditional concrete. This also ensures aesthetic freedom without sacrificing durability or performance.

Examples:

The design possibilities of GFRC are almost limitless. Here are some unique architectural GFRC examples that serve as hallmarks of unrestricted architectural creativity:

• Audrey Irmas Pavilion in Los Angeles, USA – featuring 1,230 hexagonal water-blasted concrete panels with rotated rectangular windows;
• The Veil Hotel in Astana, Kazakhstan – consisting of vertical GFRC lamellas that resemble the flowing movement of fabric pleats or drapes in the wind;
• The Imprint entertainment and hospitality complex in Seoul – is wrapped in 3,869 custom-molded GFRC panels imprinted with surrounding building facades, featuring a draped effect that creates a shadow-like relief pattern.

Sustainability

As the demand for sustainable building materials grows, GFRC perfectly fits the role: according to a UK study, GFRC has 60% less environmental impact than precast concrete.

Made from low-toxicity, recycled materials like sand and water, GFRC uses fewer natural resources, produces less waste, and its lightweight nature reduces transportation impact.

Example:

The Populus Hotel in downtown Denver will be the first carbon-positive hotel in the U.S., featuring a striking facade by Glass Fiber Reinforced Concrete skin inspired by the patterns of aspen trees.

GFRC was chosen for this project since it perfectly aligned with the hotel’s eco-conscious design while providing high-performance insulation and weather resistance.

GFRC vs. Traditional Building Materials: Exploring Advantages and Drawbacks

While we’ve explored the advantages of GFRC, the question remains: how does it compare to traditional construction materials? From weight and resistance to cost efficiency and more, review the key insights in the table below.

GFRC Traditional Materials (Concrete, Brick, Stone) Weight Lightweight, reducing foundation and structural loads Heavier, increasing the load on foundations Strength & Durability High tensile strength, due to fiberglass reinforcement Lower tensile strength, often requiring additional reinforcement Crack & Impact Strength Resistant to cracking and impact Prone to cracking, requiring frequent repairs Design Flexibility Allows complex shapes, textures, thin panels, and diverse finishes. Ideal for intricate facades and modern lightweight designs Limited to standard shapes and traditional aesthetics. More suited for classical or traditional structures Production & Installation Costs Higher material cost, but lower transport and installation expenses due to lightweight properties Lower material cost, but higher shipping and installation expenses due to weight Maintenance Costs Low maintenance, resistant to rot, mold, and weathering Higher maintenance costs, susceptible to deterioration Environmental Impact Lower carbon footprint, requires less raw material Energy-intensive production with high CO₂ emissions Recycling & Sustainability Can be crushed and reused for aggregates or landscaping Limited recycling options, often sent to landfill Thermal Insulation Good thermal performance with polymer additives Insulation requires thicker walls, which increases material use Sound Insulation Effective noise reduction due to multilayer structure Less sound insulation, often needing additional materials

Delving Into The Uniqueness of the GFRC Manufacturing Process

The manufacturing of Glass Fiber Reinforced Concrete is what sets it apart from traditional concrete materials. Understanding the entire process is crucial for architects, engineers, and builders aiming to maximize its benefits. So, let’s delve in.

Step 1: Mixing

The mixing of GFRC is a delicate balance that requires attention to detail to produce a material that meets performance expectations. The right GFRC mix ensures adequate fiber distribution, strength, workability, and the desired surface finish. As advancements in material science continue, new admixtures and methods evolve to further enhance the capabilities of GFRC.

Mixing Glass Fiber Reinforced Concrete, Pre-mix Method

Consider these several insights on GFRC components and mix recipes:

• Cement — GFRC mixes typically have a 1:1 cement-to-sand ratio, higher than conventional concrete. Common types include ordinary, rapid-hardening, and white Portland cement.
• Sand — silica sand is preferred for its ideal grain size and shape, ensuring strength and workability.
• Alkali Resistance (AR) Glass Fiber — replaces steel frame reinforcement, enhancing strength and durability.
• Water — less water = stronger GFRC; should be clean and contaminant-free.
• Acrylic Polymers and Copolymers — improve strength, curing, UV stability, and prevent cracking.
• Plasticizer — serves as a water reducer minimizing it by ~15%.
• Pigment — powder or dispersion pigments add color; higher pigment = deeper color.

Step 2: Casting

This stage involves unique premix or spray techniques to ensure the even distribution of glass fibers, resulting in a high-quality, uniform finish.

In the Premix method, glass fibers are mixed into the dry concrete blend before water and additives are added. The mixture is then placed into molds and compacted using vibration or other techniques to ensure uniformity and eliminate air pockets. This method is ideal for thin, solid panels and applications requiring precise finishes, though it is slower due to careful mixing and casting.

In contrast, the spray-up method involves spraying a wet concrete mix while simultaneously introducing fibers through a spray gun. The wet mix is sprayed directly onto a surface or mold, and the sprayed layers are built up incrementally, with each layer being compacted or consolidated to ensure proper bonding. This way, the process is faster and more suitable for large, complex, or curved surfaces. However, in this case, fiber distribution is less even, and additional finishing may be required.

GFRC Mix Casting

GFRC Casting, Spray Method

Generally, large cladding panels are produced using spray-up GFRC, while smaller components are typically manufactured with the premix method. To ensure opting for the right method, assess your project needs based on the differences listed in the table below.

Feature Premix (Direct Cast) Method Spray-up Method Mixing Process Fibers are mixed with dry materials before adding water A wet mix is sprayed, and fibers are added during the spraying Fiber Distribution More even, leading to a homogeneous mix Less even distribution of fibers Production Speed Slower, due to the need for careful mixing and casting Faster, especially for large surfaces Application Suitable for thin, solid panels and high-strength requirements Suitable for larger, complex, or curved surfaces Material Density Generally results in a denser, stronger product May result in lower density and strength due to less fiber content Finishes A finer and smoother finish can be achieved May require additional finishing work

Step 3: Curing

Proper curing allows the cementitious material to fully hydrate, which ensures the concrete reaches its full strength potential. Thanks to this process, the concrete does not dry out too quickly, reducing the likelihood of shrinkage cracks.

There are several curing techniques used in GFRC production, depending on the size, type of components, and available resources. See them listed below.

Wet Curing

This method involves keeping the GFRC wet for an extended period to allow proper hydration of the cement. Typically, wet curing is maintained for a minimum of 3 days to allow the concrete to gain sufficient strength.

GFRC Wet Curing Process: Top Advantages

• Cement’s full hydration for maximized strength;
• Prevents shrinkage cracks and surface defects;
• High resistance to weathering and impact.

GFRC Wet Curing Process

Steam Curing

With this technique, GFRC is exposed to low-pressure steam in a controlled environment to accelerate hydration and strength development. The benefits of this process include a faster curing process, quicker turnaround times for production, and better early-strength development. However, it’s important to avoid overheating, since it can damage the fibers or cause cracking if not properly controlled correctly.

GFRC Steam Curing Process: Top Advantages

• Accelerated hydration process to faster reach full strength;
• Enhanced durability thanks to controlled heat and moisture;
• Reduced curing time for quicker demolding and production turnover.

GFRC Steam Curing Process

Air Curing (Natural Curing)

In this method, GFRC cures naturally at ambient temperature and humidity, without the use of wet curing or steam. The concrete is usually kept moist for at least 3 to 7 days, with final strength development continuing for up to 28 days.

Once the curing is complete, the GFRC panels can be demolded and left to cure further in open air or controlled conditions, especially for larger or thicker pieces.

GFRC Air Curing Process: Top Advantages

• Energy efficiency and sustainability since it requires no additional energy or water;
• Minimized material stress lowering the risk of cracking or warping;
• Simple and cost-saving with no need for specialized equipment.

Step 4: Demolding

After the curing process, GFRC panels must be carefully demolded to maintain their structural integrity and surface quality. The process involves gently releasing the cured GFRC from its mold using controlled techniques, ensuring the panel retains its intended shapes, colors, and textures. Depending on the panel size and complexity, release agents may be used to prevent sticking and facilitate smooth extraction.

Once demolded, the panels undergo further curing or finishing treatments to enhance durability, strength, and aesthetic appeal. As GFRC technology advances, improved mold materials, and release techniques continue to enhance efficiency and precision in the demolding process.

Challenges and Limitations of GFRC

While GFRC offers numerous benefits, it is not without its drawbacks. Firstly, GFRC materials and production can be more expensive than traditional concrete, though savings in installation and transport may offset costs. To make a well-informed choice, consider these potential bottlenecks.

Delamination

GFRC Delamination Defect

Poor bonding between layers or improper curing can lead to delamination, where layers separate over time, reducing durability and requiring repairs.

How to efficiently address it:

Ensure proper curing and bonding techniques, use high-quality polymer additives, and avoid excessive moisture loss during manufacturing.

Cracking

GFRC Cracking Defect

Cracks can develop in GFRC due to several factors, such as shrinkage, thermal stress, rapid drying, or excessive strain on the material.

How to efficiently address it:

Implement controlled curing methods, use proper reinforcement, and optimize the mix design to enhance flexibility and crack resistance.

Surface Defects (Pitting, Bubbling, or Voids)

GFRC Surface Defect

Surface defects might occur during insufficient material consolidation during the casting or spraying process, including:

• Pitting occurs when small air voids remain on the surface after curing, leading to an uneven texture.
• Bubbling happens when excess air or trapped moisture creates raised imperfections, affecting surface smoothness.
• Voids result from inadequate material compaction, leading to weak spots that may reduce durability over time.

How to efficiently address them:

Apply vibration, compaction, or air release techniques during casting and ensure proper mix consistency.

Warping or Distortion

Warping or Distortion in GFRC

Thin GFRC panels are susceptible to warping or distortion if improper curing, uneven drying, or excessive heat exposure occurs. Uneven drying or curing, leading to shape distortion or warping in GFRC products.

How to efficiently address it:

Maintain controlled curing conditions, store panels on flat surfaces, and use reinforced framing where needed.

Excessive Moisture Loss and Dying Out

Rapid moisture loss during curing can result in insufficient hydration, leading to weaker concrete and increased shrinkage cracks.

Proper curing methods are necessary to maintain hydration levels and prevent premature drying.

How to efficiently address it:

Use wet curing methods, sealing agents, or curing blankets to retain moisture and ensure full hydration.

Segregation of Mixed Components

Improper mixing, handling, or casting techniques can cause the separation of cement, fibers, and aggregates. This leads to inconsistent material properties, weak spots, and compromised durability.

How to efficiently address it:

Follow strict mixing protocols, ensure a strict mix calculator, use properly graded aggregates, and monitor mix consistency before casting.

Limited Structural Load-Bearing Capacity

While GFRC excels in tension and flexure, its low compressive strength makes it unsuitable for load-bearing applications without additional reinforcement — including architectural elements like structural columns and beams, long-bearing walls, roof decks, bridges, and parking structures.

Unlike traditional reinforced concrete, which can support heavy vertical and horizontal loads, GFRC panels alone cannot sustain significant structural weight and must be integrated with steel, reinforced concrete, or framing systems for support.

How to efficiently address it:

Combine GFRC with steel reinforcement, concrete cores, or hybrid systems to enhance its load-bearing capacity.

Once additional reinforcement is used, GFRC can achieve the necessary compressive strength and load-bearing capacity. By integrating these reinforcement techniques, GFRC can be used in any architectural element, expanding its application beyond decorative and cladding elements while maintaining its lightweight, durability, and design-flexible properties — as illustrated in the example of an installed GFRC bridge in the image below.
