Geotechnical Investigation & Installations

Site-investigative drilling for projects of all sizes for infrastructure developments including bridges, roads and railways, water supply, dams, processing plants and buildings, jetties and wharves, etc. Drilling services include soil boring & sampling, continuous or hollow flight augers, standard penetration testing (SPT), undisturbed sampling, diamond coring, packer testing, rotary air, water, mud and down-hole hammer drilling and piezometer installation for commercial, civil and environmental projects and sonic sampling.

The following rigs have been purpose built for the geotech market;

 

MANPORTABLE DRILLING RIG

This drill has been used to confirm depths and thickness of rock for large retaining walls and house piles. The rig and power pack is easily carried into tight hard to access sites. This allows the consulting team to accrutely design a project with confindence in the geology and know the thickness off the rock rather than relying on a scala test which stops on contact of any rock. The rig is capable of cased scala testing down to a depth.

Depth Capacity coring (wire or conventional)

NQ 15 metres, HQ 10 metres, PQ 6 metres

 

 

HELI-PORTABLE DRILL RIG

Our small heli-portable drill is weights 1.1 tonnes making it possible to heli lift the rig into hard to access drilling site in one piece. Our Heli-portable drill is capable of drilling PQ, HQ, NQ core and  BQ air core, RC concentrix sampling with SPTs and push tubes. SPTs can be proformed at .05m, 1.0m or 1.5 metre interviews.

Depth Capacity coring (wire or conventional)

NQ 100 metres, HQ 70 metres, PQ 35 metres

 

 

 

 

LANDCRUISER TD110 DRILLING RIG

The Landcruiser TD110 drill rig was built for mobility and is very powerful for it size. Speight
Drilling’s aim was to build a drill rig which was easy to transport but not limited in capability.
The TD110 is capable of drilling PQ, HQ, NQ core and RC, concentrix sampling with SPTs and push tubes.
SPTs can be proformed at .05m, 1.0m or 1.5 metre interviews. It has been designed to work in challenging ground formations where other smaller rigs may fail. Having the rig mounted on a landcruiser enables quick set up times between holes and great access user 4x4 diff lock. The drill is fitted with 3 emergency stops and a spin guard for safe operation.

Depth Capacity coring (wire or conventional)

NQ 350 metres, HQ 280 metres, PQ 180 metres

 

 

CS1000 P4 DRILLING RIG

Currently mounted on rubber track unit. SPTs can be proformed at .05m, 1.0m or 1.5 metre interviews. The modern design includes safety guards and emergency stop buttons that make the rig user-friendly and safe to operate. The simple, light-weight design makes the rig easy to operate in all conditions and areas. Designed to be as simple and robust as possible, the P4 rig can be disassembled to its major components, the rig’s “fly-version” that makes transportation by Huges 500 helicopter possible.

Depth Capacity coring (wire or conventional)

NQ 610 metres, HQ 460 metres, PQ 305 metres

 

 

HD900 Wireline Drilling Rig

 

The size and weight of this tracked machine allow it to easily navigate steep hills and soft swamps. The design of this machine is simple and efficient with the drill head mounting directly on the feed ram eliminating pull down cables and pull back chains. This direct coupling makes the rig safer, lighter and the hydraulics respond quicker, drilling straighter holes. Pictures with the extra 3 metre exstenion mast bolted on making pulling of 9 metres of drill pipe for bit changes. SPTs can be proformed at .05m, 1.0m or 1.5 metre interviews. Ideal drilling rig where large rotation power is need with minamil access and machine foot print.
