The foundations of any structure are a crucial component to its overall strength, stability and longevity. One of the most reliable and versatile foundation techniques available is mini piling. Mini piling can be used for a range of construction projects, including foundations for buildings and underground tunnels. It can be installed in confined spaces where traditional piling equipment cannot, and it produces less noise pollution and disturbance than other piling methods.

The maximum depth that can be achieved with mini piling depends on a number of factors, including ground conditions and the type of piling rig being used. For example, if the groundwater level is high it can limit the maximum depth that can be reached. In these cases, it may be necessary to install a dewatering system before proceeding with the piling works.

Understanding Mini Piling: Basics and Applications

There are several types of mini piling, but the most popular option is a bored case pile. This involves a hollow steel shaft being screwed or drilled into the ground and then filled with concrete or grout. This method is ideal for constructing piles in granular or cohesive soils, and it can also be constructed in areas with artesian water.

Another option is a sectional auger pile. This is a time-efficient technique, especially useful in cohesive soils. This technique involves drilling a series of flight sections into the ground, and temporary casing can be used to help advance the bore if the soil is unstable. Once the desired pile length has been achieved, the steel reinforcement is installed and the pile bore is filled with concrete or grout.
