Why Screw Pile Foundations Are the Smart Alternative to Concrete

When it comes to foundations, concrete has long been the default choice. But in recent years, screw pile foundations (also known as helical piles) have become the go-to solution for builders, engineers, and homeowners looking for a faster, cleaner, and more flexible alternative.

At ABC Anchors, we design and manufacture high-quality screw piles in our Wiltshire factory, supporting projects across residential, commercial, and specialist sectors. In this article, we’ll explain what screw piles are, how they work, and why they’re increasingly replacing traditional concrete foundations.

What Are Screw Pile Foundations?

Screw piles are steel foundations with helical plates that are literally screwed into the ground, much like a bolt into timber. Once installed, they provide immediate load-bearing capacity without the need for excavation, curing time, or wet trades.

ABC Anchors manufactures a full range of screw piles, including 60R, 76R, 76RL, and 89R, designed to perform in a wide variety of ground conditions. With torque capacities ranging from light-duty to heavy structural loads, screw piles are suitable for everything from garden rooms to large modular buildings.

Key Benefits of Screw Pile Foundations

1. No Excavation, No Concrete

Unlike concrete foundations, screw piles require no digging, no spoil removal, and no concrete pours. This means:

• Minimal site disruption

• Cleaner installations

• Faster project timelines

In many cases, foundations can be installed and ready to build on the same day.

2. Faster Installation Times

Concrete foundations can take days - or even weeks - once excavation, shuttering, pouring, and curing are factored in. Screw piles, by contrast, are installed quickly using hand-held torque heads or small machinery, making them ideal for sites with restricted access.

For contractors, this means less downtime. For homeowners, it means projects move forward sooner.

3. Environmentally Friendly Foundations

Screw piles are widely recognised as a low-impact foundation solution. They:

• Reduce ground disturbance

• Eliminate concrete-related carbon emissions

• Can be removed and reused if required

This makes them particularly well-suited to environmentally sensitive areas, root protection zones, and projects aiming to reduce their carbon footprint.

4. Long Design Life

ABC Anchors screw piles have a design life in excess of 100 years - fully galvanised. This durability makes them suitable for both temporary and permanent structures, offering peace of mind without compromising performance.

5. Adaptable and Adjustable

One of the biggest advantages of screw piles is flexibility. They can be:

• Installed on sloping sites

• Adjusted for height during installation

• Used with various base systems

ABC Anchors’ modular foundation solutions allow buildings ranging from 2 x 2 meters up to 6 x 18 meters to be installed without excavation, even in challenging ground conditions.

Ideal Applications for Screw Piles

Screw pile foundations are suitable for a wide range of uses, including:

• Garden rooms and home offices

• Modular buildings and cabins

• Residential extensions

• Temporary structures

• Commercial and industrial buildings

• Sites with restricted or difficult access

• New build homes

Their versatility makes them a practical solution across both domestic and professional construction projects.
