Compressed fibre cement is one of the most durable and versatile building materials used across Perth and Adelaide projects. Whether you’re working on flooring, external cladding, or high-impact areas, compressed sheets offer strength, moisture resistance, and long-term performance that standard materials can’t match.
In this guide, we break down everything you need to know — from what compressed fibre cement is, to where to use it, sheet sizes, and installation best practices.
—What Is Compressed Fibre Cement?
Compressed fibre cement is a high-density cement sheet reinforced with cellulose fibres. It’s manufactured under pressure to create a strong, rigid board that can handle heavy loads and harsh conditions.
- High strength and impact resistance
- Moisture and water resistant
- Suitable for internal and external use
- Long lifespan with minimal maintenance
It’s commonly used in applications where standard plasterboard or lightweight fibre cement isn’t suitable.
—Common Uses for Compressed Fibre Cement
Compressed sheets are used in a wide range of structural and non-structural applications.
Flooring & Underlay
- Substrate for tiles in bathrooms and kitchens
- Balcony and wet area flooring
- High-load flooring systems
External Cladding
- Facade systems
- Weather-exposed walls
- Architectural finishes

—Wet Areas
- Bathrooms and laundries
- Commercial kitchens
- Areas exposed to constant moisture
High-Impact Zones
- Garages and workshops
- Commercial fit-outs
- Public access areas
Compressed Fibre Cement vs Standard Fibre Cement
While both materials are made from similar components, compressed sheets are significantly denser and stronger.
| Feature | Compressed Fibre Cement | Standard Fibre Cement |
|---|---|---|
| Density | High | Moderate |
| Strength | Very high | Moderate |
| Weight | Heavy | Lighter |
| Applications | Structural / high-load | General cladding |
Standard Sheet Sizes & Thickness
Compressed fibre cement sheets are available in a range of sizes depending on the application.
- Thickness: Typically 6mm, 9mm, 12mm, 15mm, 18mm+
- Width: Usually 1200mm
- Length: Commonly 2400mm to 3000mm+
Thicker sheets are used for flooring and structural applications, while thinner sheets are used for walls and linings.
—How to Install Compressed Fibre Cement
Proper installation is critical due to the density and weight of compressed sheets.
Basic Installation Steps
- Ensure framing is level and properly spaced
- Use appropriate fibre cement screws or fixings
- Allow for expansion gaps where required
- Seal joints and edges correctly
Compressed sheets are often installed over systems like: Steel Framing
—Important Considerations
Before using compressed fibre cement, there are a few key things to keep in mind.
- Heavier than standard boards — requires proper handling
- Needs correct tools for cutting (dust control recommended)
- Must be installed to manufacturer specifications
- Requires proper sealing in wet areas
For internal areas, it’s often paired with: Plasterboard Systems
—Is Compressed Fibre Cement Waterproof?
Compressed fibre cement is highly water-resistant but not completely waterproof on its own.
- Resists moisture penetration
- Does not swell like timber
- Requires sealing or waterproofing systems in wet areas
This makes it ideal as a substrate rather than a finished waterproof surface.
