Why Screw Piles Are a Great Alternative to Concrete Foundations

6 days ago3 min read

When it comes to building projects, the foundation is key. A solid foundation provides the stability and support a structure needs to stand the test of time. Traditionally, concrete foundations have been the go-to solution. However, there are situations where concrete isn’t a feasible option due to site conditions, environmental concerns, or time constraints. In these cases, screw piles offer an excellent alternative.



What Are Screw Piles?

Screw piles, also known as helical piles, are a type of foundation that is screwed into the ground rather than poured or driven. They consist of steel shafts with helical plates that allow them to be installed quickly and with minimal disruption. Once installed, they provide a stable base for various types of structures, from residential buildings to commercial projects.


When Concrete Foundations Aren’t Suitable

There are several scenarios where concrete foundations may not be the best option:

  1. Restricted Access: Sites with limited access for heavy machinery can make pouring concrete difficult or impossible.

  2. Poor Soil Conditions: In areas with weak or unstable soil, achieving the necessary bearing capacity for a concrete foundation can be challenging.

  3. Environmental Sensitivity: Concrete production and installation can have significant environmental impacts. Projects in environmentally sensitive areas may benefit from the low-impact installation of screw piles.

  4. Tight Deadlines: Concrete requires time to cure, which can delay project timelines. Screw piles, on the other hand, can be installed and used immediately.

  5. Temporary Structures: For projects requiring removable or adjustable foundations, screw piles offer unmatched flexibility.


Not just a Concrete Alternative - Benefits of Using Screw Piles

If you’re considering screw piles as an alternative to concrete foundations, here are some compelling benefits:

1. Quick Installation

Screw piles can be installed in a fraction of the time it takes to pour and cure a concrete foundation. Using hand-held or mini-digger-mounted torque heads, installations can often be completed in just one or two days.

2. Minimal Disruption

Because screw piles don’t require excavation, they are ideal for sites where preserving the surrounding environment is a priority. This is especially beneficial in areas with tree root protection zones or on sites with uneven terrain.

3. Environmentally Friendly

Screw piles produce less waste and require fewer resources than concrete foundations. They’re also reusable and relocatable, making them a sustainable choice for temporary or semi-permanent structures.

4. High Load Capacity

Despite their slender design, screw piles can support impressive loads. ABC Anchors offers a range of screwpiles with torque capacities from 4 kNm to 22.5 kNm, making them suitable for various applications.

5. Versatility

Screw piles are compatible with a range of structures, from small modular buildings to larger commercial developments. They’re also adjustable, making them an excellent choice for sites with gradients or other challenges.

6. Cost-Effective

By reducing installation time and the need for heavy equipment, screw piles often prove to be more cost-effective than traditional concrete foundations, especially on challenging sites.


Applications for Screw Piles

Screw piles are versatile and can be used for:

  • Residential extensions

  • Modular buildings and log cabins

  • Temporary structures

  • Decks and patios

  • Bridges and boardwalks

  • Subsidence repairs


If your project is in an area where concrete foundations are impractical, screw piles offer a smart, efficient, and sustainable alternative. At ABC Anchors, we specialise in high-quality screw pile solutions that are tailored to meet the unique needs of each project. With a life expectancy of over 100 years when galvanised, screw piles provide long-lasting performance you can trust.
