What Helidrill accomplishes

Helidrill own and operate 4 Heliportable top drive rigs, the 2 main rigs are currently track mounted, with one easily removed from the tracks so that it can be flown, craned etc into place.

The rigs can be broken down into several parts, and flown to remote locations or locations that are inaccessible by road, they can be shifted by Helicopter.

Once on site they only require a 10 x 6m platform. Helidrill also has huts and associated camping equipment that can be flown to the site so that we can camp on site to negate the need to be dependant on the weather for flying to and from the rig each day.

Diamond Drilling

Helidrill has 2 main Diamond Drilling rigs that are capable of the following depths:

Rig One

PQ – 80 metres
HQ – 180 metres
NQ – 250 metres

Rig Two

PQ – 150 metres
HQ – 300 metres
NQ – 400 metres

The other smaller rigs are used for holes less than 50 metres.
Site Investigation Drilling

Site Investigation is used to determine the suitability for building sites, bridges and other structures. Any of the 4 rigs can be used for this purpose, depending on location and the depths and diameter of the holes that are required. The following services are also offered as part of the Site Investigation Drilling.
SPT Testing

Split spoon and spike SPT gear.
Pushtube Coring

Pushtube coring gear for coring very soft ground and for coring through a casing advance system, touch coring and moisture content testing.
Piezometer Installations

For ground water level monitoring.
Inclinometer Installations

For ground movement monitoring.
Siezmic Line Drilling

Any one of the 4 rigs that Helidrill has are suitable for seismic line drilling. For shallow depth seismic holes, one of the smaller rigs is mounted onto the back of the 4WD Suzuki, this allows the drilling to be completed on valuable farm land with minimal impact to the pasture or crops.
Drainage Holes

We offer drainage drilling for draining water out of landslides, building sites, from under roads and railway lines etc.

our equipment

TD150 – Rig 1

A heliportable drilling rig, built in 2009. This rig is capable of drilling to the following depths:

PQ – 80 metres
HQ – 180 metres
NQ – 250 metres

It is mounted on a Mitsubishi LD400 dump Truck, which is on rubber tracks. It can be moved easily between holes and is especially useful for wet or swampy ground.
By using the Mitsubishi the rigs requires minimal support because all the drill rods and other drilling equipment can be carried with the rig.
The rig can be easily removed from the deck of the dump track and put back on its base frame. This allows it to be flown or craned onto sites that aren’t accessible by land.  
TD250 – Rig 2

This rig is track mounted and also Heliportable. It was built in 2010. This rig is capable of drilling to the following depths:

PQ – 150 metres
HQ – 300 metres
NQ – 400 metres


The blade mounted on the front, allows the rig to level its own pad. It is a very compact rig, for the depths that it is capable of drilling to.
Tractor Mounted – Rig 3

This rig is suitable to mount on the back of a 100hp Tractor, with a maximum drilling depth of approx 50mtrs. It can used for:

Seismic Lines
Shallow Water Bores
Vertical Blast Holes
Wash Drilling
Jackro – Rig 4

A small rig that is very useful for holes of a depth less than 10mtrs. It can be mounted onto the back of the 4wd Suzuki, or flown onto site and mounted onto its own base frame. The type of holes that it is most suited for are:

Seismic Lines
Soil Sampling
Shallow Coring Holes
Anchor Holes
Blast Holes in Large Boulders
Drainage Holes
Cable Holes
Small Instrumentation Holes
Komatsu Rod Carrier

Brought in 2010 for the Croydon job, this is the dinosaur of the team and affectionately known as Deano. The unit is track mounted and has a lifting arm, perfect for carrying the rods, pumps gear, etc between sites and those heavy lifting jobs.
Suzuki

The baby of the team, that has been christened puddles. A great little 4WD machine, that has heaps of grunt and is nice and light, making it perfect for getting in and out of those tricky spots. It is also very useful when doing Seismic lines as it allows the drilling to be completed on valuable farm land with minimal impact to the pasture or crops.
