At MACt, we understand the precision and care required to manufacture Glass Fibre Reinforced Concrete (GFRC) that not only meets but exceeds industry standards. Through our extensive experience and dedication to quality, we’ve identified seven critical mistakes that can compromise the integrity of GFRC products. Here’s what every manufacturer needs to avoid:

1. Inappropriate Binder Use

Selecting the right binder is foundational to achieving the structural integrity and durability expected of GFRC. MACt emphasizes the importance of using the correct type and quantity of binder, as deviations can lead to subpar performance and safety concerns. Our training courses delve into the specifics of binder selection to ensure optimal results.

2. Mismanagement of Fibre Content

The strength and flexibility of GFRC heavily rely on the type and amount of fibre incorporated. Using inappropriate fibres or incorrect quantities not only undermines the material’s properties but may also pose safety risks. MACt’s GFRC range and training programs are designed to educate on the precise formulations needed for superior GFRC.

3. Incorrect Aggregate Choices

The choice of aggregate affects the texture, weight, and overall performance of GFRC. At MACt, we guide manufacturers in selecting the proper type and amount of aggregate to match the desired outcome, ensuring the final product meets all necessary requirements and quality benchmarks.

4. Inaccurate Mixing Techniques

Precision in mixing is crucial for the homogeneity and performance of GFRC. Incorrect mixing can lead to inconsistencies and weaknesses in the final product. MACt’s workshops provide hands-on experience in achieving the perfect mix, using techniques that have been refined over years of practice.

5. Using Expired or Contaminated Materials

The quality of materials used significantly impacts the integrity of GFRC. MACt insists on the use of fresh, uncontaminated materials to ensure the final product’s performance and safety. Our professional GFRC product line is guaranteed to be of the highest quality, ensuring reliability in your manufacturing process.

6. Exposure to Extreme Conditions

GFRC’s sensitivity to environmental conditions means that extreme temperatures and humidity levels during manufacturing can alter its properties. MACt’s manufacturing environment is meticulously controlled to prevent such exposure, ensuring consistent quality across all products.

7. Neglecting the Curing Process

Proper curing is non-negotiable for GFRC, affecting everything from strength to surface finish. Skipping or rushing this process can have dire consequences. At MACt, we adhere strictly to recommended curing practices, a principle that is central to our training courses as well.

MACt’s Commitment to Excellence in GFRC Manufacturing


Understanding and avoiding these seven mistakes are fundamental to producing high-quality GFRC. At MACt, we not only follow these principles in our manufacturing processes but also teach them in our comprehensive GFRC 2-day training course held in Brisbane. By combining our professional GFRC product range with expert-led training, we equip manufacturers with the knowledge and tools to excel in GFRC production, ensuring safety, durability, and aesthetic excellence in every project.
