The foundations of a building are arguably the most important part of any construction project, from adding a basement to your home to underpinning an existing building. It’s no secret that piling is the most efficient and cost effective method of strengthening a structure’s foundations, however a lot of builders aren’t aware that there are different methods of piling that can be used depending on the circumstances.

Mini pile is a method of foundational piling that can be used when standard piles wouldn’t work due to a lack of headroom or restriction on space. Essentially it involves steel driven tubes being screwed into the ground using specialist machinery. This process has a number of advantages over conventional piling techniques.

The Advantages of Mini Pile Foundations: A Comprehensive Overview

There are a few different types of mini pile that can be employed depending on the ground conditions and requirements for a particular project. Mini pile can be constructed from a variety of materials including concrete, steel, and precast piles.

One of the most commonly used methods is called sectional auger mini pile, this consists of installing the supporting shafts in segments to accommodate for a lack of headroom or space and can be achieved by utilising various drilling techniques including rotary-percussive, cased and auger. It is also the most adaptable of all the piling options when it comes to varying soil conditions as it can be completed with either an open bore or temporary casings. It is also capable of resisting lateral and uplift loads.
