Description

 

When it comes to marine salvage and heavy lifting, Marine Rubber Airbags offer unmatched strength and adaptability. Available in custom diameters and lengths (up to 5m), they provide controlled buoyancy for sunken vessel recovery, dock repairs, and cargo transfers. Built with multi-ply rubber reinforcement, they withstand sharp debris and high-pressure conditions. Their modular design allows multiple airbags to work in unison, supporting massive loads safely. Easy to transport, inflate, and reposition, they are the go-to solution for emergency responders, offshore operators, and wreck removal teams.
