Our Services

An anchor is a structural component, which carries tractive forces to the ground, the slope or the rock. These forces occur during foundation engineering.

Capping beams are structural elements made of steel and concrete. Capping beams create the foundation for the slab and helps hold the earth and the neighbouring houses back.

Piling is a common construction technique on projects of all sizes. It involves driving in supporting members that will form the deep foundations required to support large and heavy structures.

These piles allow for the placing of structures in areas that would otherwise be unable to support them due to the conditions of the soil on and under the surface. The length of the piles transfers the load of the structure away from the unstable areas, and moves it deeper into the ground where it is better supported.

Piling is a quick and cost effective method of strengthening the foundations of a building when done during initial construction, as the piles can be driven straight into the ground without the need for any drilling.

When an existing foundation needs to be strengthened, this is often done with micropiles, a process known as Underpinning.

Piling works best in soft or weak soils, and these soil types are also where you are most likely to need piles to support structures. Soils that are silty, sandy, or high in clay are prime candidates for piling, as is anywhere that is marshy or has a high water table.

Piling is also commonly used when a structure has to support very heavy and concentrated loads, such as bridges, water tanks, and high rise buildings.

Pilings are usually made of one of three different materials: wood, steel, or concrete.

Wooden piles are highly economical and easy to install, but their size is limited by how big a tree trunk can be sourced. 

Steel piles are quick to install and are ideal for hammering into rock or sturdy soil, but will degrade and eventually fail if installed into corrosive soil. Steel is used when installing Screw Piles.

Concrete piles can be precast offsite, or cast in situ directly into the ground onsite. They resist corrosion and can be installed in standing water, but are very heavy to move and install.

Don’t know what kind of pile you should use? Don’t stress, we’ll tell you as part of our assessment of the site.

We’ll also assess your site to determine the correct size and depth of pile for your job. What depths can we do? Whatever you need! We can customise equipment to complete a variety of depths, so you’ll always have the right size.

Specialised heavy rock coring up to 12.4m deep. Full range of core barrel sizes (125mm – 1500mm) engineered for basalt, rhyodacite, and restricted civil sites

Engineered Rock Coring for Difficult Ground

When standard auger rigs hit impenetrable rock, basalt, or rhyodacite, core barreling is the essential engineering solution. By cutting a clean annular ring rather than pulverizing solid rock, our rigs reduce ground resistance, cut drilling time, and lower linear-metre costs.

Technical Specifications & Capacity:

• Core Barrel Diameters: 125mm, 300mm, 450mm, 600mm, 750mm, 900mm, up to 1500mm.
• Auger Support: Full range of rock augers (90mm to 2000mm) to clear core plugs in mixed ground.
• Drilling Depths: Equipment engineered for rock shafts up to 12.4 metres deep.
• Restricted Site Solutions: Zero-clearance drilling flush against existing walls, custom casing setups adjacent to Telstra poles without supporting cranes, and tail-boom excavator setups for cliff faces.
• Full Turnkey Scope: Supply & installation of steel reinforcement cages, concrete pouring, and capping beams.

Drilling through metres of earth and rock is no simple business, there’s a lot to consider before making a decision on what size and method is the one to go with.

When drilling with a standard auger isn’t viable, care barrelling is usually the operation that saves the day. With less surface area to cut thanks to the relatively thin walls of the barrel, resistance is greatly reduced and the shaft can be drilled quicker and more efficiently.

Our extensive range of available core barrel sizes is second to none:

125mm – 300mm – 450mm – 600mm – 750mm – 900mm – 1500mm

Sometimes an auger is required to augment the core barrel, which we will determine as part of our assessment of the soil foundations. If an auger is required to support the core barrelling process, we have an exhaustive range of augers for drilling through all kinds of rock.

Our augers are available in a wide range of sizes:

90mm – 140mm – 250mm – 300mm – 350mm – 450mm – 500mm – 600mm – 750mm – 900mm – 1200mm – 1500mm – 2000mm

Our barrels and augers can drill to a depth of up 12.4 metres.

Do you have a difficult or unusual job to complete? We’ve engineered solutions for a wide variety of projects that would leave other companies scratching their heads.

We have the ability to drill against existing walls without any risk of damaging the wall.

Our team can prepare custom-made casings that enable us to safely drill against existing Telstra poles without the need for a supporting crane.

We also possess the expertise to configure a tail boom to allow an excavator to drill over cliff faces.

Upon request we are able to supply and install the cages, concrete, and capping beams you need to finish the job.

We can safely and effectively drill in sandy and muddy conditions.

We are able to custom design whatever parts are required to complete the job, no matter how tough or complicated the circumstances.

We can custom design:

• Vertical casings for Continuous Flight Augers
• Alignment systems for straight/vertical piers
• Drill casings
• Smudge bars
• Buckets
• Hammers

Think you’ll struggle to get everything onto your job site? Think again. We can arrange the truck and float needed to transport the necessary machinery and parts anywhere in Australia or Tasmania.

Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope)

Underpinning may be accomplished by extending the foundation in depth or breadth so it either rests on a more supportive soil stratum or distributes its load across a greater area. Use of micropiles and jet grouting are common methods in underpinning.

An auger is a drilling device, or drill bit, that usually includes a rotating helical screw blade called a “flighting” to act as a screw conveyor to remove the drilled out material.
