Description
Product Overview
Fabbay’s 4 Pack Fiberglass Fiber Additive is engineered to provide a high‑performance reinforcement solution for a wide range of cement‑based applications. Each pack contains 8.8 lb of premium glass chopped strands that are specifically sized at 3/4 inch to 19 mm, delivering a balanced mix of flexibility and tensile strength. The fibers are uniformly distributed throughout the mix, creating a dense matrix that resists crack propagation, improves impact resistance, and reduces water infiltration. The product dimensions of 12.2 × 9.45 × 7.48 inches make storage and handling straightforward, while the total net weight of 8.69 lb per pack ensures consistent dosing for both small‑scale DIY projects and larger professional jobs.
Manufactured by Fabbay, a trusted name in construction materials, this fiberglass additive meets rigorous quality standards and carries an ASIN of B0BLXT3V5Z. It has earned a solid 4.6‑star rating from over 119 verified customers, reflecting its reliability and performance in real‑world conditions. The product is positioned in the Industrial & Scientific category, under Raw Materials > Laminates & Composites > Fiberglass, and holds a competitive Best Sellers Rank of #73 in Fiberglass Raw Materials.
Usage
This fiberglass additive is versatile and can be incorporated into a variety of concrete, mortar, and grout mixes. Ideal for garden walls, retaining structures, decorative countertops, and exterior facades, the fibers enhance the structural integrity of the substrate, making it more resistant to freeze‑thaw cycles, vibration, and mechanical impact. To achieve optimal results, blend the fibers with sand and cement in the recommended proportion, then add water gradually while stirring for an additional 30 to 60 seconds longer than a standard mix. This extended mixing time ensures the fibers are fully wetted and evenly dispersed, preventing clumping and guaranteeing uniform reinforcement throughout the matrix.
For projects in high‑moisture environments, such as pool decks, water‑retaining walls, or outdoor patios, the anti‑seepage properties of the fibers help to limit water penetration, extending the lifespan of the structure. In colder climates, the added toughness reduces the likelihood of micro‑cracks caused by thermal expansion and contraction, providing a more durable finish that can withstand harsh weather conditions.
Whether you are a seasoned contractor working on a commercial build or a homeowner tackling a weekend renovation, the product’s clear packaging and straightforward mixing instructions make it accessible for users of all skill levels. The 4‑pack configuration offers flexibility: you can use a single pack for small repairs or combine all four for larger pours, ensuring you have the right amount of reinforcement for any job size.
Why Choose Us
Choosing Fabbay means selecting a product backed by years of material science expertise and a commitment to quality assurance. Each batch of fiberglass fibers undergoes stringent testing for tensile strength, length consistency, and resistance to chemical degradation, guaranteeing that the fibers perform as advertised across a range of environmental conditions. The brand’s reputation for reliability is reinforced by its transparent manufacturing processes and responsive customer support, which includes detailed technical guides, mixing charts, and after‑sales assistance.
Our fibers are lightweight yet exceptionally strong, allowing you to achieve a higher reinforcement ratio without adding excessive weight to the mix. This characteristic is especially valuable in applications where load‑bearing capacity and ease of handling are critical, such as prefabricated panels or thin‑wall constructions. Additionally, the anti‑crack and anti‑seepage benefits translate into lower maintenance costs and longer service life for the finished structure, delivering tangible value to both residential and commercial stakeholders.
Fabbay also prioritizes sustainability. The glass fibers are produced using energy‑efficient processes, and the packaging is recyclable, aligning with green building practices and helping you meet environmental certification goals.

FAQ
How much water should I add when mixing the fibers with cement?
Start with the water amount recommended for your standard cement mix, then increase the mixing time by 30‑60 seconds. This extra stirring ensures the fibers are fully wetted and evenly dispersed, preventing clumping.
Can I use this product for outdoor concrete slabs?
Yes. The anti‑seepage and crack‑resistant properties make it ideal for outdoor slabs, patios, and driveways that are exposed to moisture and temperature fluctuations.
Is the product safe to handle?
The fibers are non‑hazardous, but it is advisable to wear a dust mask and gloves during mixing to avoid irritation from fine particles.
What is the recommended dosage for a standard 1 m³ concrete batch?
For a typical 1 m³ batch, use one full 8.8 lb pack of fibers. Adjust the amount proportionally if you are mixing larger volumes or require higher reinforcement.
Do the fibers affect the color of the finished concrete?
The fibers are white and blend seamlessly with most cement mixes, leaving no visible discoloration in the cured product.
