Inflatable Brattice Walls, Tunnel Plugs & Pipe Plugs

Australian-Made Ventilation & Flow Control Solutions for Mining, Tunneling & Industrial Projects

Fleximake leads the Australian market in manufacturing high-performance inflatable brattice walls, tunnel plugs, and pipe plugs. We design these products to improve airflow, seal off airflow, and close off pipelines, tunnels, and industrial sites. Our systems make it easier to control airflow, odour control, keep workers safe, and manage dust in underground areas.

You can reuse them, making them a more environmentally friendly choice than single-use timber, steel, or plastic alternatives.

Why Choose Fleximake Inflatable Solutions?

     Each product is precision-engineered using CAD to match your tunnel, shaft, pipe, or duct dimensions for a secure and airtight seal.
  • Fast & Easy Installation
    Our inflatable units set up quickly and easily. Designed for quick unpacking and hassle-free inflation with clear instructions.
  • Durable & Reusable Materials
    Made from high quality  heavy-duty, UV-stabilised, tear- and puncture-resistant fabrics.  Its designed for repeated use across multiple jobs.
  • Portable & Space-Saving
    Compact shipping and easy transport between job sites nationally and internationally.
  • Environmentally Responsible
    Reduce waste by replacing bulky timber, plastic, and steel ventilation systems with reusable inflatable alternatives.
