Precast Piles for Wastewater Tanks: A Strong Foundation

Piling is a type of deep foundation, used to transfer the load to a deeper level than is possible with a traditional shallow foundation. Vertical columns of concrete, steel or timber, or a combination, are driven deep into the ground to give extra support to the building that sits on top. When conditions require, piling contractor, Aarsleff Ground Engineering can install all three on one site.

Precast concrete piling involves the use of precast concrete piles, which are manufactured off-site and then transported to the construction site for installation. They are driven into the ground, using a piling rig equipped with an impact hammer. These piles serve as foundational support for various structures and are especially beneficial for wastewater tanks.

Precast piles offer several advantages for wastewater sites, making them a preferred choice in foundation construction. Some key benefits include:

• Precast piles are manufactured off-site in a controlled environment, leading to increased efficiency and reduced on-site labour costs.
• The high-quality materials and controlled manufacturing process contribute to the long-term durability of precast piles. Their resistance to corrosion and degradation ensures a stable foundation for wastewater structures over time.
• Piles of various size, length, and shape can be made in advance and used at the site. As a result, the progress of the work will be rapid.
• Driven piles maintain their shape during installation. They do not bulge in soft ground conditions and are typically not susceptible to damage from the installation of subsequent piles.
• Driven piles require no curing time and can be driven in natural sequence rather than skipping alternate piles, thus minimising the moving of the equipment and speeding up installation time.
• The equipment and installation methods are time-tested and well proven. Advances in materials, equipment, methods, and testing continually combine to improve the efficiency of driven piles.

The benefits of precast piles for wastewater sites include cost-efficiency, minimal environmental impact, adaptability to various soil conditions, enhanced load-bearing capacity, rigorous quality control, and long-term durability. These advantages make precast piles a favourable choice for foundation construction in wastewater infrastructure projects.
