Drilling in sensitive areas

Foundation work and ground engineering with Wassara

Minimal impact on ground water table

Urban areas are often considered as sensitive and must not be affected by side effects from a drilling operation. This means that no impact is allowed on the ground water level, or any injection of oil or air to the formation.

No risk of harming buildings

When drilling with Wassara, the risk of pressurising the formation is minimised as the water quickly lose pressure when leaving the hammer. When drilling with air-powered equipment, there is always a risk of pressurising the formations. If the formation is filled with cracks or cavities, the expanding air may cause hazard to adjacent structures.

Better work environment

Air-powered drilling in urban areas often face environmental restrictions in terms of allowed noise level and injection of oil or dust to the air. Wassaras water-powered drilling gives no injection of oil or dust in the formation, and is far quieter than top hammers since the percussion takes place down in the borehole.
