MINI PILING

Sectional Flight Auger (SFA) piling is a type of auger-bored replacement pile that is ideal for use in areas with limited access or low headroom.

This method is similar to Continuous Flight Auger (CFA) piling, but it uses shorter sections of a hollow-stem auger instead of a continuous one.

WHAT THEY’RE USED FOR

SFA piling performs exceptionally well in open environments across a wide range of soil types, including made ground, clay, weak rock, gravel, glacial till, and areas with high water tables. Its adaptability to these varied substrates highlights its effectiveness in accommodating the geological diversity often encountered in construction projects.

In urban areas or confined spaces where conventional equipment may have difficulty operating, SFA piling offers a practical and efficient alternative. Its segmented auger design allows for precise drilling and pile installation in tight spaces, addressing the challenges posed by restricted access or overhead obstructions.

The versatility of SFA piling extends beyond just geological factors, also encompassing logistical and environmental considerations. Its ability to work through different soil types and challenging site conditions while maintaining efficiency makes it a preferred choice for projects where adaptability, performance, and reliability are essential.

In summary, SFA piling is a versatile and adaptable solution capable of overcoming a wide range of site-specific challenges, making it an indispensable tool in modern construction projects where restricted access, limited headroom, and diverse soil conditions pose significant obstacles.

THE PROCESS

SFA piles are an advanced foundation solution that uses sectional hollow-stemmed augers to provide strong and reliable structural support. This innovative approach offers numerous benefits across different ground conditions, making it the go-to choice for projects where precision, efficiency, and performance are essential.

The process starts with the insertion of a sectional hollow-stemmed auger into the ground to create boreholes that align with the project’s specifications. As the auger penetrates the soil, it removes arisings, effectively clearing the borehole and ensuring smooth operation in various ground conditions.

Once the borehole reaches the required depth, concrete or grout is pumped through the hollow stem of the auger as it is gradually withdrawn, maintaining a continuous flow. This ensures no voids form during the auger’s extraction, resulting in a solid and stable pile. The final step involves inserting reinforcement, which further strengthens the pile’s structural integrity and load-bearing capacity.
