Strong Foundations Start with Smarter Solutions

When you’re building in Burnie, you need to think from the ground up — literally.
The strength and stability of any structure depend on one thing: its foundation. And in Tasmania’s North-West, with its diverse soils and variable weather, that foundation needs to be tough, precise, and built to last.

That’s why more builders, engineers, and homeowners across Burnie are turning to screw pile foundations — a modern, efficient, and dependable solution for all types of construction.

At Mirage Building & Construction, we specialise in screw pile design and installation that ensures your structure stands firm for decades to come. Whether you’re working on a new build, an extension, or need to stabilise an existing foundation, our team brings local knowledge, technical skill, and genuine care to every project.

 

What Are Screw Piles — and Why They’re Changing the Game

Screw piles (also called helical piles) are steel shafts fitted with helical plates that are literally “screwed” deep into the ground to create an anchor point for your building. They transfer structural loads from above into stable soil layers below, providing a solid and reliable base.

Think of them as giant steel screws holding your building steady — no matter what’s happening beneath the surface.

Why They’re a Better Choice

Screw piles have become one of the most trusted modern foundation solutions because they offer:

• Speed: Installed quickly, with no curing time like concrete footings.

• Strength: Designed for impressive load-bearing capacity in a range of soil types.

• Precision: Installed to engineered torque and depth, ensuring maximum stability.

• Minimal Disruption: No large excavations or concrete trucks — cleaner and quieter installation.

• Immediate Use: Structures can be built on top as soon as the piles are in.

For Burnie projects where access, weather, or soil conditions make traditional foundations tricky, screw piles are the smart, modern alternative.

 

Why Screw Piles Are Perfect for Burnie Conditions

Tasmania’s North-West Coast is one of the most beautiful regions in the country — but its diverse terrain presents unique challenges for construction.

From the sandy soils along the coast to the clay and loam further inland, Burnie builders need foundations that can handle it all.

Here’s why screw piles work so well here:

1. Adaptable to Local Soils
   Screw piles are designed to reach deeper, more stable soil layers. Whether you’re on the slopes near Parklands or the low-lying areas around Cooee, we can tailor the depth and size of each pile to suit your ground conditions.

2. Great for Coastal Sites
   Near the shoreline, where salt and moisture can affect traditional foundations, screw piles perform exceptionally well thanks to corrosion-protected steel and engineered coatings.

3. Ideal for Sloping or Limited Access Sites
   Many Burnie builds happen on tricky terrain. Screw piles can be installed with compact machinery that fits into tight or uneven areas without disturbing your landscape.

4. Fast and Efficient
   Because there’s no waiting for concrete to cure, screw piles speed up the entire building process — perfect for projects that need to stay on schedule.

5. Reliable in All Seasons
   Whether it’s a dry spell or heavy rain, screw piles can be installed in most conditions, unlike traditional footings that depend on weather and soil moisture.

 

Applications of Screw Piles in Burnie

Our team at Mirage Building Foundations installs screw piles for a wide range of residential and commercial projects.

Some of the most common applications include:

• New home foundations

• Extensions and renovations

• Decks, patios, and pergolas

• Retaining walls and fencing

• Underpinning existing structures

• Commercial and industrial slabs

• Boardwalks, ramps, and temporary structures

Screw piles are incredibly versatile, making them suitable for almost any structure that needs a solid footing in Tasmanian conditions.

 

The Mirage Building Process

At Mirage Building, we treat every screw pile installation as a precision job — because the entire structure depends on getting it right.

Here’s how our process works:

1. Site Assessment

We begin by assessing your site conditions — checking soil type, access, water levels, and load requirements.
If needed, we’ll review geotechnical reports to ensure our design fits the site perfectly.

2. Design and Engineering

Every screw pile project is tailored. We determine the right pile size, number, and depth based on the expected loads and ground resistance.

3. Installation

Using specialised hydraulic equipment, our team screws each pile into the ground to a pre-set torque, ensuring secure anchoring. This process is quick, accurate, and low-impact.

4. Testing and Verification

Once installed, each pile is load-tested to verify it meets structural and engineering standards. You’ll know your foundation is solid before construction begins.

5. Integration

We connect the piles to your footing or slab system, ready for the next stage of building.

6. Clean-Up

Our team always leaves the site tidy and ready for the next trades to move in.

Throughout every stage, we maintain clear communication so you always know what’s happening — and when.

Screw Piles vs. Traditional Concrete Footings

If you’re wondering how screw piles compare to traditional foundations, here’s a simple breakdown:

Feature	Screw Piles	Concrete Footings
Installation Time	Fast, immediate load capacity	Slower, requires curing
Soil Suitability	Excellent in variable soils	Limited in unstable conditions
Site Disruption	Minimal excavation	High excavation and mess
Weather Dependence	All-weather capable	Limited by wet or cold conditions
Load Testing	Real-time torque verification	No direct load feedback
Access	Compact equipment	Large machinery needed
Environmental Impact	Low	Higher due to concrete and spoil removal

For Burnie’s changing soils and tight urban spaces, screw piles often provide a superior, more practical foundation solution.

 

When Screw Piles Are the Ideal Choice

You may want to consider screw piles if:

• Your site has unstable or reactive soil

• You’re building on a sloped or tight-access block.

• You need a foundation solution that can be installed quickly.

• Your structure requires deep anchoring for extra stability.

• You’re adding an extension or second storey.

• You need an underpinning for a settling home.

If any of these sound familiar, the team at Mirage Building can inspect your site and determine whether screw piles are the best fit.

 

Common Questions About Screw Piles

Q: How long do screw piles last?
Properly installed, galvanised steel screw piles have a very long service life, designed to withstand Tasmanian soil and climate conditions for decades.

Q: Can screw piles be installed on existing buildings?
Yes. They’re ideal for underpinning and stabilising homes with foundation movement or cracks.

Q: How deep do screw piles go?
Depth varies depending on soil conditions and engineering requirements. Our installers monitor torque levels to ensure each pile reaches a stable stratum.

Q: Is the process noisy or messy?
Not at all. Installation is far quieter and cleaner than traditional excavation, with little to no spoil.

Q: Do I need council approval?
Most structural work requires engineering certification, and we can assist in obtaining the necessary approvals.
