Tested and Proven

Unique Group’s buoyancy bags are designed to provide maximum amount of lift for the least overall height with 5:1 minimum safety factor. Wide hem aids swifter emptying of the bag on emergency inversion. The single attachment point helps keep our bags inherently stable, regardless of load orientation or trim.


Our lifting bags are made from tensile Trevira® Polyester base cloth and are coated in heavy-duty PVC. Trevira is an extremely strong material with a break load of one tonne.


Unique Group’s lifting bags take up very little space storage relative to their lift capacity.


Carefully designed, constructed and tested to meet and exceed demanding international standards. Seaflex underwater lifting bags fully comply with IMCA D-016 guidelines.
