Inflatable Grout Packers
Inflatable packers are available in diameter sizes of 1″- 2″, 2″- 3″, 3″ – 4″, 3″- 6″, 4″- 7″ and 5″- 8″. 
Lengths range from 355mm up to 1.5m or more. 
With their sliding head design, they have the ability to double in size from their run-in diameter and typically furnish a longer seal than that of a mechanical packer. 
These packers have integral tube scrapers that remove excess grout that has adhered to the outside of the center tube and work each time the packer is deflated.
