Understanding The Basics Of Screw Piling
Screw piling has proved to be a reliable and cost-effective way of laying foundational structures. The technique involves driving a screw pile into the soil, which then forms a solid connection with the foundation of a building. The popularity of screw piling has led to an increased demand for foundation contractors that have the expertise to install screw piles. This post will walk you through the basics of screw piling and how it works.
What are screw piles?
Screw piles are essentially designed as large screws that are driven into the ground instead of being drilled or cast in place. They are made up of tube segments that are screwed into the soil until they reach the required depth and are then filled with concrete. The piles come in different sizes and lengths, depending on the load they'll be supporting. The screw pile design is more versatile than traditional foundations as it does not only work in soil and rock, but it can also interact with bedrock and other compressible classes of soil.
The benefits of using screw piles
Screw piles offer a range of benefits over other foundational techniques, making them popular with contractors and property owners alike. They are quicker to install, which means reduced project times and lower labour costs. Due to their pre-manufactured design, screw piles can be transported to the site easily and require minimal site preparation, reducing the impact on the surrounding environment. They are cost-effective, with lower material costs as compared to traditional foundation methods. The installation process has minimal vibration, which means there is not going to be any disturbance to the surrounding soil.
Choosing the right screw pile
When selecting the type of pile to use, several factors come into play, such as soil quality, site location and duration and the weight of the building that will sit on top of it. The size and number of screw piles you'll need will depend on each site's specific requirements, so a thorough site assessment needs to be conducted. Working with a qualified contractor to choose the right pile is essential in ensuring the success of your project.
The installation process
The installation of screw piles is a relatively straightforward process. The contractor secures a drilling rig in position, which then drives the screw pile steadily into the soil. Once the screw pile is at the correct depth, it is filled with concrete, and all pipes installed are cut off at a pre-determined height below ground level. Then, the installation is left to cure, and the building work above commences.
