The inflatable packers are suitable:
- for grout injections and pumping tests in deep bore holes, where the time consuming installation is eliminated
- in case of abrasive and fractured rocks to permit uniform expansion of the rubber sleeve following the contours of the borehole until the required diameter is reached
- when maximum working pressure and wear resistance should achieve very high values.
Standard sealing lengthes for single or double packers are 500 and 1.000 mm.
