Inflatable Plugs & Isolation Systems
INFLATABLE PLUGS & ISOLATION SYSTEMS
Pressure control, isolation and forming systems for mining and industrial applications
PolyFusion designs and manufactures inflatable plug systems for mining and industrial environments where isolation, pressure control or void forming is required.
These systems are used to seal shafts, isolate headings, manage pressure zones and create temporary or permanent separation in underground and surface operations.
From isolation plugs through to inflatable formwork systems used in concrete and remediation applications, each solution is engineered to suit the installation environment, load requirements and operating conditions.
Why inflatable plugs are used
Inflatable plugs provide a practical solution for isolating areas, controlling pressure and forming temporary barriers in environments where rigid systems are difficult to install or remove.
Their ability to conform to irregular surfaces and create controlled sealing makes them well suited to underground mining, processing environments and infrastructure work.
Compared to fixed or constructed barriers, inflatable systems can be deployed quickly, adjusted as required and removed when no longer needed, reducing downtime and improving operational flexibility.
ISOLATION & PRESSURE CONTROL
Sealing and separating active and inactive areas
Inflatable plugs are commonly used to isolate shafts, headings and process areas where controlled separation or pressure management is required.
These systems can be used to restrict airflow, manage pressure zones or prevent material movement between sections of a site.
Where required, plug systems can be integrated with ventilation controls and protection systems to support safe and controlled working conditions.
FORMING & REMEDIATION SYSTEMS
Inflatable formwork for concrete, void forming and rehabilitation
Inflatable plug systems can also be used as forming systems in concrete and remediation applications, where controlled voids or barriers are required during placement.
These systems are used to form plugs in shafts, create voids in filled structures and support staged pours where controlled geometry is critical.
Unlike traditional formwork, inflatable systems can be installed quickly, removed easily and adapted to suit the application, reducing labour requirements and simplifying installation in confined environments.
Applications in shafts, raises and infrastructure
Inflatable plugs are widely used in vertical and inclined environments such as shafts, ventilation raises and ore passes where access is limited and installation conditions are challenging.
Their flexible design allows them to be positioned and inflated in place, creating effective sealing or forming systems without the need for complex installation methods.
These systems are suited to both temporary and permanent works, depending on the application and materials used.
SITE PRACTICALITY
Fast deployment and adaptable installation
Inflatable plug systems can be transported easily and installed with minimal equipment, making them ideal for underground and restricted-access environments.
Their ability to be deployed quickly reduces downtime and allows work to proceed without the delays associated with traditional construction methods.
Reusable designs also allow systems to be repositioned or redeployed across multiple applications, improving efficiency and reducing overall project cost.
Common applications
• Isolation of shafts, headings and underground work areas
• Pressure control and sealing of ventilation pathways
• Concrete plug forming and staged pours
• Void forming in shafts, raises and filled structures
• Remediation and rehabilitation works
• Temporary or permanent separation of site zones
CUSTOM PLUG SYSTEMS
Designed for site-specific performance and conditions
PolyFusion manufactures custom inflatable plug systems designed to suit specific site requirements, including pressure conditions, geometry, material selection and installation constraints.
These systems can be integrated containment systems, inflatable systems and protection systems to deliver complete, controlled solutions.
Each system is developed with a focus on performance, reliability and practical use in real operating environments.
