Sides continue to be the industry leaders in the area of high tolerance large diameter
for dam remediation, port infrastructure and mining infrastructure.
Sides own and operate Australia's largest down hole hammers and offer both single and their own gang designs in sizes up to two meters and in both conventional and reverse circulation configurations with matching pipes drill collars stabilisers and swivels.
The Sides gang hammers are available in a number of sizes and configurations. The hammers are setup specifically for the application using a variety of hammers. To date the maximum depth drilled using a gang hammer system has been 500 metres at 750mm diameter single pass Tower Colliery in New South Wales through Sydney basin sandstone. These depths have been attained with blind hole drilling, greater diameters and depths are possible if we drop cuttings into underground workings. These massive tools quickly and cheaply drill holes large enough for man recovery shafts in mines, accurately drill pre-bores for raise drills or form hard pile rock sockets for piles on land or at sea. Sides have the necessary expertise and specialised rigs, heavy drill pipe, stabilisers, compressors and barges to support these massive tools in almost any situation.
Sides has the in house expertise and resources to customise rigs to suit specific site access requirements:

John Holland Group |
Ross River Dam |
Scope involved drilling, waterproof grouting, redrilling, water testing, and alignment surveys of a total of 9 off vertical 310mm nominal anchor holes to an average depth of 50 metres.
Tolerances required
Diameter +/- 4mm
Straightness +/- 1 in 200
Alignment / Direction along hole axis +/- 1 in 100 |

Clough Engineering |
Bunbury Berth #6 Wharf Construction |
Sub contracted to Clough Engineering Ltd, Sides was tasked with the drilling of 28 off vertical & raked (1:4) 24” 610 mm diameter sockets through marine sediments and basalt. Sides customised a rig for the project and utilised the SDS RC240 hammer system. The hammer in question is the largest reverse circulation type currently in Australia.

Southern Rural Water |
Lake Narrican Dam Upgrade |
Retained by Southern Rural Water Sides was tasked with the drilling and grouting phase of the overall upgrade works needed on the Lake Narracan Dam. The scope of works required 311mm diameter holes to be drilled over a length of 50 metres to a tolerance of 1:250. Due to the condition of the dam, an innovative approach was required to minimise the loadings placed on the dam. The rig constructed was evenly balanced producing zero turning moment on the dam. |

Walter Construction |
Canning Dam Upgrade |
Sides was contracted by Walter Construction to drill 175 off 311mm & 340mm anchor holes up to 130m depth at a tolerance of 1:400 as part of the strengthening upgrades to the dam. These were we understand the world’s largest anchors at the time |
