Drilling & Pressure Grouting
- Auger Drilling: Uses a helical screw blade (auger) to remove soil from the borehole. Suitable for soft soils.
- Rotary Drilling: Employs a rotating drill bit to break up and remove soil and rock. Effective for harder materials.
- Percussion Drilling: Uses repeated hammering or impact to break up soil and rock. Common in hard ground conditions.
- Reverse Circulation Drilling: Involves pumping air or water through the drill bit and collecting cuttings via the outer annulus. Used in mineral exploration and geotechnical investigations.
- Soil and Rock Sampling: Collecting samples for analysis to determine soil properties and ground conditions.
