Augering Christchurch
Clean holes. Controlled positions.
Excavator augering and hole boring across Christchurch and Canterbury for retaining poles, foundations, structural posts and civil or rural projects.

Common auger diameters
Matched to the specified hole.
Available diameter and achievable depth depend on the excavator, auger setup, ground conditions, access and the engineering requirement. Confirm the required diameter and depth before pricing.

Excavator-mounted augering
More accurate and efficient than excavating an oversized hole.
Where ground and access allow, an auger produces a controlled circular excavation with less unnecessary spoil and disturbance around the intended pole or footing position.
TBT provides operated excavator and auger capability as part of standalone boring work or a wider earthworks package. The hole layout, diameter, depth, services and engineering requirements remain project-specific.
Retaining-wall polesHoles bored to the design layout, diameter and depth before pole placement and concrete.
Foundation and structural postsBoring for specified pole, pile or footing positions where excavator augering is suitable.
Large fence and gate postsEfficient hole construction for substantial rural, commercial or boundary infrastructure.
Civil and rural workProject-specific boring incorporated into access, drainage, structural and property-development works.
Auger diameter selected around the project requirement
Plant and cartage available for the wider site scope
Machinery matched to access and ground conditionsWhat the service includes
From setup to clean handover.
Augering is most effective when positions, services and specifications are established before the machine arrives.
Position and specification confirmation
The client, surveyor or engineer provides the required centres, diameters, depths and tolerances.
Controlled boring
Holes are advanced according to ground response, with excavated spoil managed around the work area.
Wider earthworks support
Excavation, access, cartage, retaining, drainage and backfill can be included where the project needs more than boring.
Before augering starts
Know what is below and above the work.
Service location and site hazards must be addressed before drilling. Unknown services, rock and unstable ground can materially change the work method.
Underground servicesPlans and physical locating completed as appropriate before excavation.
Overhead hazardsPowerlines, trees and structures checked against boom and auger movement.
Ground conditionsFill, gravels, groundwater and rock may affect production and achievable depth.
Engineering informationDiameter, depth, centres and reinforcement requirements confirmed by the relevant designer.
A straightforward workflow
What we need to price it.
01 / LOCATION
Address and access photos
Show the route to the work, available room, slopes and surrounding structures.
02 / HOLE SCHEDULE
Quantity, diameter and depth
Provide the number of holes and the specified dimensions for each group.
03 / GROUND
Known soil or geotechnical information
Any information about rock, fill, groundwater or previous excavation helps define the setup.
04 / SCOPE
Any associated earthworks
Confirm whether access, spoil removal, pole placement, retaining or excavation is also required.
Common questions
Augering and hole-boring FAQs.
How deep can you auger?
Achievable depth depends on auger setup, excavator, diameter, ground conditions and access. Send the required depth so the correct configuration can be confirmed.
Can an auger drill through rock?
Standard augering may stop or become inefficient in hard rock. Rock breaking or a specialist drilling method may be required depending on the material and design.
Do you provide geotechnical drilling?
No. This page covers excavator-mounted construction augering, not geotechnical investigation, core drilling or soil sampling.
Can you bore retaining-wall holes?
Yes. Retaining pole holes are a core application, provided the engineering layout, diameter, depth, access and ground conditions are suitable.
Do you dry-hire augers or excavators?
No. TBT provides machinery with experienced operators rather than dry hire.
Can spoil be removed?
Yes. Spoil can be stockpiled, spread where appropriate or carted away as part of the quoted scope.
