Inflatable Grouting Packers
Why use an inflatable grouting packer?
Inflatable packers are specified on many pressure grouting jobs to provide a superior seal against grout bleed. They are required for stage grouting and up-hole grouting from tunnels and galleries.
Tigre Tierra® Inflatable Grouting Packers are designed to deliver unmatched performance on the toughest pressure grouting jobs. No mechanical packer or home-made plug comes close.
Features include:
- Steel cable reinforced glands
Our glands retain run-in diameter and hold dimensional stability throughout their service life. Other packers may feature glands strengthened with synthetic fibers. Demand steel cable to protect your investment.
- Best ratio of through-pipe I.D. to packer O.D. in the industry
For example, 1.66" O.D. packers are available with ¾" I.D. center tubes. That means smooth, high volume grout flow so that you can do the job right and do it fast.
- Stainless steel center tubes
Standard with every packer so that you never have to worry about pitting or corrosion.
- Integral tube scrapers
Remove grout adhering to the outside of the center tube each time the packer is deflated.
- Easy field service and repair
You don't need to take our packers back to the shop for disassembly. Your crew can do everything in the field using common hand tools.

Packer sizes range from (in/mm) 1.20/30 to 6.69/170 O.D. to pack bores from (in/mm) 1.3/33 to 13/330 O.D. |
