Katana Foundations Screw Piles

Katana Foundations Screw Piles Our name comes from the Japanese Samurai sword. Like a ‘Katana’, our curved twin-fin blade ‘slices’ through underlying strata leaving no spoil to remove.

We go the extra mile when estimating, supplying and installing your screw piles so that you have peace of mind your foundation is constructed on-time and certified to Engineering specifications. After 26,000 jobs and 1.5 million screw pile installations, we have established a reputation as Australia’s most reliable screw pile supplier for our transparency, performance, and technical expertise. And

our patented threaded square pile head eliminates hot works on site and supports slab on ground and raised floor systems. The Katana Pile is a market leading, "twin fin" screw pile made from all Australian 400 grade high-tensile steel, and is manufactured in Brisbane QLD from Australian raw materials. This unprecedented strength means that the Katana Pile can be installed in most soil types and geological conditions. With a 50+ year design life guarantee, the Katana Pile and its associated products can be used in conjunction with all types of concrete slabs, as well as timber and steel flooring systems. The Katana Pile has been designed to allow for custom made attachments to be manufactured for portable building applications, sloping sites and generally difficult building site conditions. Katana Foundations uses highly accredited installers whom have all been trained and certified by industry experts. We cover all areas of Queensland, New South Wales, Victoria, Tasmania and South Australia. Since our founding in 2012, our philosophy has been to install screw piles properly, and do it better than anyone else. Our mission is to service the Australian and New Zealand Residential Building markets with the highest quality steel screw piling products and foundation and flooring systems, installed to exact specifications, with a very transparent process. We will not compromise on the best quality Australian steel piles manufactured by Australian workers. If you are a civil contractor or concreter and want to expand your business by installing 100% Australian made screw piles, then please get in touch with us.

What actually stops a screw pile from pulling straight back out of the ground?

Mark demonstrates it using nothing more than a scale model and dry beach sand.

As the pile screws deeper, it becomes harder to turn. That resistance is measured as torque, and once the required torque is reached, it gives an indication that the pile has reached its required capacity.

Did you expect dry sand to hold it that firmly?

If one helix gives you 150kN, does adding another really give you 300kN?

In theory, you might expect it to.

But when the first helix is driven through the ground, it disturbs the soil above it. That means the second helix doesn’t necessarily have the same bearing conditions or carry the same load.

That’s why we take a more conservative approach and rate our twin-helix pile at 200kN rather than simply doubling it to 300kN.

Would you have expected the second helix to double the capacity?

Are you designing screw piles to their strengths?

Screw piles work particularly well when they’re working in tension and compression.

For applications like retaining wall footings or pedestrian bridge abutments, using piles as a couple can help eliminate the bending moment of a single pile and significantly reduce lateral and shear forces at the top of the pile.

It’s not just about specifying screw piles. It’s about designing the footing to take advantage of how they work.

How are you using tension and compression in your foundation designs?

800kg of steel or 38,000kg of concrete - which would you choose?

That’s the difference we’re looking at when comparing screw piles with concrete bored piers for the same foundation scenario.

Preliminary Swinburne University results are showing 84% less Global Warming Potential and 77% less Energy Consumption for the manufactured product.

And we haven’t even reached the end-of-life comparison yet.

Do numbers like these change how you think about foundation design?

That’s much closer to the Katana description style we’ve established.

Would you have approved this first design? 👇

Every great product starts somewhere.

When we set out to create an adjustable foundation system, our first prototype definitely wasn't the sleek solution we have today.

It worked but it was overcomplicated.

After plenty of engineering, testing and refinement, we developed the patented attachment nut you see today: a much simpler solution that allows the bearer plate to be adjusted after installation.

What's the most over-engineered solution you've seen on a job site?

How do you normally secure reinforcing to your piles?

Some systems require drilling through the pile. This solution allows reinforcing to be clamped using attachment nuts and the integrated top plate without drilling through the pile.

It's a simple engineering detail designed to help preserve the structural integrity of the pile while making reinforcement easy to install.

👇 We'd love to hear from the industry.

Do you:
🔹 Drill through the pile?
🔹 Weld to the pile?
🔹 Use an attachment system?
🔹 Something else?

Not every pile detail is just a design choice.

A concrete footing sitting directly on a cut pile or a pile without a bearing plate can create significantly higher bearing stress than one designed to distribute the load properly.

That's why details below ground matter just as much as the structure above it.

Would you ever pour concrete onto a cut pile, or do you always use a bearing plate?

👇 Let us know in the comments.

Many piling systems use drilled holes to connect extensions. While effective, those holes can introduce bearing stress to the pipe wall and create potential points where corrosion may begin over time.

That's why we use an end-to-end connection system designed to transfer torsion while keeping the pipe free of holes.

Because when it comes to foundations, the smallest design details can make a big difference.

Not all steel is equal.

When it comes to foundations, material quality plays a critical role in long-term performance, durability and reliability.

That's why we use Australian steel.

Would you compromise on steel quality to save cost?

👇 Comment YES or NO.
