Geonor is a leading supplier of various types of wing drills, which are a safe, accurate and well-established method for in situ measurement of undrained shear strength in soft clays. The wing-drill technology is so well established as a tool that the equipment has formed the basis for international geotechnical standards.

The largest international markets for wing drills are in regions where marine clay and quick clay are a challenge for the construction industry.

Geonor manufactures and supplies three types of wing drills; H-60 (0-3 meters), H-70 (0-10 meters +) and H-10 (0-30 meters +)
