Boral supplies inert filler aggregates for use in a range of construction and industrial applications where a consistent, non‑reactive material is required.
Produced from carefully selected raw materials and processed to controlled grading, Boral’s inert fillers are used as supplementary components in cement‑based products, epoxy resin systems and specialist construction applications.
Features and Benefits
Non‑reactive material
Suitable for use as an inert component in cement and resin systems where chemical stability is required.
Consistent grading
Processed to deliver predictable particle size and performance across mixed and blended applications.
Broad system compatibility
Used across construction, repair and industrial systems requiring reliable filler performance.

Applications
Cement‑based systems
Boral inert filler aggregates are commonly used in cement‑based products, including:
- Construction grouts
- Repair mortars
- Renders and screeds
- Tile adhesives
- Shotcrete and specialty blends
In these applications, inert fillers help support workability, grading control and cost efficiency while maintaining performance requirements.
Epoxy resin and specialty systems
Inert filler aggregates are also used in epoxy resin and polymer‑modified systems, including:
- Resin flooring systems
- Waterproofing systems
- Textured coatings and finishes
- Line marking and repair applications
Their controlled properties make them suitable where predictable behaviour within resin systems is required.
Why use inert filler aggregates
Inert fillers are specified where a stable, non‑reactive material is required to support grading, system performance and cost efficiency within cement or resin‑based formulations, without introducing unwanted chemical interaction.
This makes inert filler aggregates a practical component in a wide range of construction and industrial systems.
Product quality and availability
Boral inert filler aggregates are:
- produced from selected raw materials
- processed under controlled conditions
- supplied through Boral’s packaged products network
As with all natural products, some variation may occur; however, processing controls are in place to support consistent performance for typical construction and industrial applications.
