Drilling in sensitive areas


When drilling with Wassara, the risk of pressurising the formation is minimised as the water quickly lose pressure when leaving the hammer.

Casing advancing


The water lubricates the casing, which enables a smoother drilling operation. When casing advancing in longer holes, Wassara is often the only feasible method.

Energy and geothermal drilling


When minimal borehole deviation is crucial, Wassara has proven its capability to drill long straight holes that are not affected by the water table.

Jet-grouting


The Wassara Jet-grouting- hammer enables single pass jet-grouting in difficult formations. This eliminates the need for more than one drill rig and jet-grouting equipment.

Maritime drilling


With the Wassara-hammer, the capacity and speed is maintained during the whole operation, the surrounding water does not affect the drilling.
