What Is a Screw Pile?

A screw pile (also called a screw pier, helical pile, or steel screw pile) is a deep foundation element manufactured from high-strength steel. Each pile consists of a central shaft with one or more blades welded to the lower section. During installation, a hydraulic drive head rotates the pile into the ground until it reaches the minimum design requirements.

Screw piles function as ground anchors that transfer building loads below the surface. The helical blades engage the soil and create resistance against both compression and tension forces. This load transfer mechanism provides stable support for structures ranging from residential decks to multi-storey commercial buildings.

Screw pile foundations have transformed Australian construction practices over the past three decades. For a comprehensive overview of how this technology has shaped the industry, read our guide to screw piling in the Australian construction market.

Types of Screw Piles Compared

Steel screw piles vary by shaft profile, blade configuration, and load capacity.

Australian construction projects use four primary screw pile types, each suited to specific soil conditions and structural requirements.

Pile Type	Shaft Profile	Load Capacity	Installation Accuracy	Best For
Round Shaft (Single Helix)	76.1-273mm	up to 1000Kn	★★★☆☆	General residential, light commercial
Twin-Blade (Blade Pile) Recommended	76.1-273mm with twin-blade	up to 1000Kn	★★★★★	All residential, commercial, challenging soils
Multi-Helix	88.9-323mm	Up to 1000kN+	★★★★☆	Heavy commercial, tension anchors

Choosing the correct pile type depends on various factors such as geotechnical conditions, design loads, and installation access.

For an in-depth exploration of each configuration, visit our complete guide to types of screw piles.

Blade Pile’s Proprietary Technology & In-House Automation

Blade Pile manufactures screw piles from high-strength steel: 450-grade for 76mm shafts and 350-grade for larger sizes with wall thickness from 4mm to 12.7mm

All components undergo robotic welding to Australian standards.

In-house engineering team provides site-specific pile designs based on geotechnical conditions.

The Twin-Blade Screw Pile Advantage

At Blade Pile, we use our own symmetrical twin-blade design. Unlike single-helix alternatives, the twin-blade configuration creates balanced forces during rotation, improving installation verticality and compression performance.

Instead of pushing large amounts of soil aside, the steel blades cut cleanly into the ground. This helps to minimise movement, which is especially important when working near existing buildings and services.

Screw piles achieve their strength by transferring structural loads into competent soil layers beneath the surface. During installation, we continuously monitor the installation torque- the resistance encountered as the pile advances into the ground. Reaching the specified torque provides a direct, measurable indication that the required load-bearing capacity has been achieved. This real-time verification allows us to confirm that the foundation is structurally sound and ready to support the building.

Feature	Engineering Benefit	Practical Application
Symmetrical twin-blade design	Balanced forces during rotation	Improved verticality in variable soils
180° blade spacing	Equal torque distribution	Consistent penetration without pile wander
End-bearing mechanism	Load transfer to specific soil strata	Torque reading confirms capacity
Cutting blade action	Reduced soil disruption	Installation closer to existing structures

Benefits of Screw Pile Foundations

Screw pile foundations offer clear, practical advantages over traditional concrete piling and other foundation methods.

Screw pile installation completes approx 60-80% faster than concrete foundations. A standard residential foundation of 60-70 piles installed under 1 day.

60-80% Faster

Screw piles bear full design loads immediately after installation. No curing period, no waiting for concrete strength. Builders begin slab preperation on the same day piles are installed.

Zero Wait Time

Screw pile foundations cost up to 30% less than equivalent concrete piling. Savings come from reduced labour, eliminated soil removal, no concrete materials, and shorter project duration.

60-80% Faster

Screw pile installation produces zero excavation spoil. Helical blades displace soil downward rather than removing it. Small equipment suits restricted access sites.

Zero Spoil

Screw piles perform in all types of soil from sand to reactive clays. Engineers adjust shaft diameter, helix configuration, and depth to match site-specific conditions.

All Soil Types

Steel piles contain 15–25% recycled content and are up to 100% recyclable. No water required for mixing or curing. No chemical additives enter the soil.

100% Recyclable

FAQs

What are screw piles?

Screw piles, also known as screw piers or steel screw piles, are deep foundation solutions made from steel. They are screwed into the ground to provide stable support for structures, offering an alternative to traditional concrete piling. Screw piles are highly versatile and can be used in various soil conditions, making them an excellent choice for many construction projects.

How long do screw piles last

Screw piles have a design life of 50+ years in standard Australian soil conditions. Hot-dip galvanisation protects against corrosion. Projects in aggressive soils (high salinity, acidic pH) may require additional protective coatings to achieve the same lifespan.

How are screw piles installed?

Screw piles are installed by screwing them into the ground using specialised equipment. This process causes minimal ground disturbance and can be completed quickly, making it an efficient foundation solution. The installation does not require any curing time, allowing for immediate load-bearing and progression to the next stage of construction.

Can screw piles be used in wet conditions?

Yes, screw piles can be installed in wet conditions, making them a versatile solution for various environments. They are designed to provide stability and durability even in challenging conditions. This makes screw piles an ideal foundation solution in areas with high water tables or unpredictable weather conditions.

Can screw piles be used in clay soil?

Yes. Screw piles perform well in clay soils, including reactive clays common in Melbourne, Adelaide, and South East Queensland. Piles extend below the reactive zone (typically 2-4 metres) to stable ground unaffected by moisture changes, preventing foundation movement.

Do I need council approval for screw piles?

Yes. Screw pile foundations require the same building approvals as concrete footings. Blade Pile provides complete engineering certification and documentation packages that satisfy council and building certifier requirements across all Australian states.
