• Used to obtain continuous, undisturbed soil samples.
• Comprises a cutting shoe, tube and catcher being pushed into the ground via machine.
• Fast, simple and safe operation.

• Widely used for soil sampling, groundwater monitoring and/or temporary drill casing.
• “Hollow” describes their ability for drill rods to pass through their centre, to take undisturbed samples for analysis or to install pipe for ground monitoring.
• Auger cutter head and pilot bit break up ground material while auger ‘flights’ act as a screw to move dirt from the bottom of the hole.

• Steel and tungsten blades are used to bore a hole while compressed air is injected into the hole to remove drill cuttings.
• Downhole percussion hammers can also be utilised.
• 50mm PVC monitoring well can be installed at depths of up to 60 meters.

• A drilling system used to penetrate through overburden in diamond and well drilling.
• Time and cost efficient system.

• Non-destructive vacuum excavation services.
• Used to expose or excavate around underground services, such as electrical and communication cables, water, gas, storm water and sewerage pipe work.
• Non-destructive method of digging ensures minimal risk of damage to buried assets, compared to mechanical excavators which can easily damage existing underground services.
• Provides a risk-free means of safely exposing underground cables and pipes which often run in different directions at various depths.  
• Vacuum units transfer the spoils directly into the spoils tank of the unit with no unsightly piles of dirt in the work area. 
• No machinery tracking back and forth means minimal ground disturbance to the site surrounds, results in a minimal footprint on the work area and minimising access restrictions
