Void Liners
Custom Void Liner Solutions for Underground and Structural Applications
Raven Liners designs, manufactures, and installs custom void liners for construction, infrastructure, and underground applications across Australia. Our void liner systems provide reliable containment and long-term protection for cavities, basements, tunnels, and enclosed void spaces where water ingress, contamination control, or structural protection is required.
Each void liner is engineered to suit the exact geometry, size, and site conditions of the cavity. By tailoring every solution to the project environment, we help maximise the use of unused or inaccessible spaces while maintaining safety, durability, and compliance.
What are Void Liners Used for?
Void liners are flexible containment systems installed within enclosed or irregular cavities to isolate liquids, manage water storage, or prevent the migration of moisture, gases, or contaminants. They are commonly used in underground voids, building cavities, service tunnels, and structural spaces where traditional rigid tanks are not practical.
These systems allow otherwise unused spaces to be converted into functional storage or protected zones without altering the surrounding structure.
Key Advantages of Void Liner Systems
- Designed to fit cavities of any shape or size
- Suitable for underground and concealed installations
- Compatible with mains water and rainwater systems
- Flexible membrane adapts to natural building movement
- Accommodates internal piers, sumps, walls, and structural elements
- Helps optimise unused or wasted building space
Professional Void Liner Installation
The installation of void liners requires precise measurement, careful surface preparation, and controlled installation techniques to ensure long-term performance. Raven Liners manages the entire process, from site assessment through to final installation, ensuring each void liner performs as intended.
Our experienced technicians use specialised equipment to achieve accurate fitment and secure encapsulation, delivering reliable results even in complex or restricted spaces.
Tailored Void Liner Solutions for Complex Cavities
Irregular voids and structural cavities often remain unused due to their shape and limited access. Raven Liners specialises in designing custom void liners that adapt to complex geometries, allowing these spaces to be safely utilised or protected.
If you need a void liner solution tailored to your project requirements, our team can assess your site and provide a practical, engineered outcome.
