Why are screw piles popular in low-rise construction?

Low-rise construction requires a special approach to foundation selection to ensure the reliability and durability of the structure. One of the most popular and effective solutions today is screw piles. In this article, we will examine the main reasons for their popularity, their advantages, and their applications.

Basic Concepts

Screw piles are steel pipes with helical blades at the end that are screwed into the ground. This design provides high stability and load-bearing capacity, making them an ideal solution for various types of buildings.

Reasons for the Popularity of Screw Piles

1.       Ease and Speed ​​of Installation. Screw pile installation takes minimal time, which is especially important in tight construction schedules. Installing one pile takes anywhere from a few minutes to an hour, depending on the soil type and equipment. This significantly speeds up construction, allowing for the next stages to begin much sooner.

2.       Cost-Effective. Screw piles do not require complex preparatory work, such as excavation or formwork. This reduces construction costs and makes construction more affordable. Furthermore, there is no need for large volumes of concrete, further reducing costs.

3.       Versatility. Screw piles are suitable for use on all types of soil, including soft and marshy soils. This makes them an ideal solution for construction in a wide variety of conditions, from urban environments to remote rural areas.

4.       Minimal Environmental Impact. The installation of screw piles has a minimal impact on the environment. The lack of need for extensive excavation and the low waste generation make this method environmentally friendly and gentle on the landscape.

Application of Screw Piles

Screw piles are often used for foundations under private homes and cottages. They provide reliable support and stability for the structure, preventing deformation and subsidence. This is especially important in areas with unstable soil or high groundwater levels and resistance to aggressive environmental conditions. Each product undergoes strict quality control to ensure its compliance with established standards.

In addition to residential buildings, screw piles are widely used for the construction of various outbuildings, such as bathhouses, garages, terraces, and fences. Their versatility allows them to create strong and durable foundations for a wide variety of structures. Resistance to aggressive environmental conditions. Each product undergoes strict quality control to ensure its compliance with established standards.

The Installation Process

The installation of screw piles involves several stages:

1.       Site Marking: This stage involves planning and marking the site. Specialists determine the installation locations for each pile, taking into account design requirements and soil characteristics. Marking ensures uniform load distribution on the foundation and prevents errors during installation.

2.       Pile Driving: The piles are driven into the ground using specialized machines or manually. The choice of method depends on the soil type and construction conditions. Machine driving ensures greater speed and precision, while manual installation is suitable for sites with limited access for machinery. Specialized equipment helps ensure the correct depth and angle of pile installation.

3.       Leveling: After installation, the piles are leveled to ensure the foundation is horizontal. Leveling is performed using laser levels or other precise measuring instruments. This prevents distortion and ensures structural stability.

4.       Pile Cap Installation: The final stage involves installing pile caps on the piles, which serve as the foundation for further construction. The pile caps ensure a strong connection between the piles and the above-ground structure, evenly distributing the building load onto the piles.

Each stage of the screw pile installation process requires careful preparation and execution. Proper site marking, professional screwing, precise alignment, and installation of the pile caps are the key to creating a strong and reliable foundation. These tasks are performed by experienced specialists using modern equipment, guaranteeing the high quality and durability of the screw pile foundation.
