Traditional piling involves using a pile driver to smash piles into the ground under hydraulic action. Mini piling, however, typically involves inserting smaller piles with a narrower diameter with lighter equipment. 

Mini piles are smaller than conventional piles, but also more expensive. That is because they need to support a given load of weight using less material. 

To construct a mini pile, operatives first lower a hollow steel shaft into the ground and drill it into place. They then pour in concrete and grout to form the pile while the steel shaft prevents soil contamination. Unlike in traditional boring, there is no need for additional supports to hold back weak soil. 

In some cases, construction operatives may use sectional mini piles for foundations. This process involves drilling into the soil and then adding supporting sections in sequence. It is a popular technique in weak soil situations or where a project requires deep piles. 

Mini piling, just like regular piling, comes with benefits. However, which you choose will depend on the job itself. 

Mini piling tends to be most beneficial in confined spaces. Because the piles are smaller, so too is the equipment required to insert them into the ground. Clients often request mini piling in heavily built-up areas because it causes less noise and vibrations. 

As with regular piling, mini piling has a range of applications. These include residential properties, office buildings, bridges and industrial installation, such as wind farms.
