Why Screw Piling Is Best For Your Construction Project
When it comes to construction, you’ll know a solid foundation lays the base for the entire project’s success. Screw piling is a robust and reliable foundation system that has been gaining popularity in recent years. As a cost-effective and versatile solution, it provides an excellent alternative to traditional foundations.
Key takeaways:
- Screw piles are a versatile alternative to traditional foundations in construction like concrete.
- They generate less environmental disruption due to less noise and vibration, and the need for minimal excavation.
- Screw piling is suitable for a range of construction projects including residential, commercial, and infrastructure.
What Are Screw Piles?
Manufactured from steel, screw piles consist of a steel shaft with helical plates attached to the bottom of them. These helical plates allow the pile to be screwed into the ground creating a stable foundation with tension, compression and lateral bearing capacity.
They’re a versatile solution for a range of applications, including:
- Residential construction, like family homes
- Boardwalks, decks or jetties
- Commercial construction, such as retail stores or offices
- Solar panel installation
- Pipelines above ground, and creek or river crossings
- Infrastructure projects like bridges and highways
How Do They Work?
The screw pile is rotated into the ground by a hydraulic motor. This creates a screw-like effect that anchors the pile into the soil, forming a deep foundation for structures. Screw piles can be used with or without concrete, and can be installed on sites with limited access.
They can hold a large amount of weight due to the helical plates that anchor the pile to the ground. Their ability to withstand lateral forces makes them an ideal solution for high-rise buildings and bridges.
Are Screw Piles Right For My Project?
There’s plenty to consider when choosing the foundation for your construction. To ensure you’ve made the right choice, you need to think about:
- Topographical location: are there any hills or is it difficult to access?
- Weather conditions and climate: hot weather can impact the use of concrete through early setting.
- Soil bearing capacity: your soil type will impact how much it can bear.
- Economical design: what are your budget constraints?
Screw piles can be used in a range of construction projects but it’s important to consider the pros and cons of using them compared to other foundation solutions.
The Advantages Of Screw Piles In Construction
Cost Efficiency
The cost of screw piles in Australia will vary depending on the construction project. However, they provide a more cost-effective solution to other foundation systems like concrete piles. Overall costs are reduced by fast installation, their long lifespan, and minimal maintenance as opposed to other systems.
Environmental Impact
For an environmentally-friendly option, screw piles provide an excellent solution. Their installation generates less environmental disturbance due to minimal excavation, noise and vibration. They’re also recyclable and can be removed and reused in other projects.
Weatherproof
Although the weather in Western Australia is usually pleasant, another benefit of screw piling is it can be installed year-round, regardless of rain. Other foundation systems need dry conditions, whereas screw piles can be installed in wet ground which reduces the impact of weather on project schedules.
Versatile Application
Screw piles are suitable for a range of different soil conditions including soft soil, sand, clay, silt, and rock. They’re flexible in terms of installation depth and can be used in places where mixing and pouring concrete would be impractical.
Ease Of Installation
Screw piles can bear weight immediately after installation, unlike other methods which require curing time. As screw piling installation doesn’t need any excavation or heavy machinery, the process is much quicker and less disruptive, minimising project downtime.
Screw Piles Vs Bored Piles- What’s Best?
Bored piles are a foundation method that requires drilling directly into the ground to create a borehole. The hole is then filled with concrete and reinforced with steel. While bored holes are a common and often effective foundation method due to their ability to hold heavy loads, they require extensive excavation, curing time, and suitable ground conditions.
In comparison, screw piling provides numerous advantages, making them a cheaper, quicker, and more environmentally friendly option.
Frequently Asked Questions About Screw Piles
Can screw piles be installed in any soil?
Yes. Screw piling is suitable for a range of soil conditions including rock, clay, and sand, making them a sturdy and versatile foundation.
How long do they last?
When properly installed, screw piles can last for over 75 years. This depends on the soil conditions, but you can expect a long-lasting result.
Will having screw piles installed be disruptive?
No. Screw piles are a quick and non-disruptive foundation solution. Due to excavation and curing time not being required, they are ideal for saving time and resources.
