What is Mini Piling and Why is It Important?
Piling helps to ensure a sturdy foundation from the installing heavy posts or stakes in the subsurface. There are various kinds of deep foundation piling, as well as the micropile is one of them. Known as 'mini piling', micropiles are deep foundations developed with heavy-duty steel casings and/or threaded bars which are small in diameter, usually three to 10 inches. The casing is installed employing a specialised drilling equipment and method. An all-thread bar can serve as reinforcing steel in mini piling, which is often inserted in to the casing with the micropile. The capacities can vary according to the profile in the subsurface as well as the size with the micropile. Mini piling has been used effectively on structures with capacities exceeding 1,000 tonnes.

Mini piles had been applied only on certain ground conditions due to factors like speed and value. Without proper equipment, mini piling is slow and tedious as a result of the flushing and drilling processes involved in it, resulting inside the job possibly taking hours to be accomplished. However, technological advancements in equipment, machinery, and technique are making mini piling traditionally used in additional applications, particularly if from the project must adhere to low vibration and no-noise regulations, which are common in congested environments like towns.

Geotechnically speaking, mini piling is smart in ground conditions like shallow bedrock, intermediate hard strata, underpinning, cavities and boulders. Concrete piles like reinforced concrete square and spun piles can certainly produce a lots of noise during the driving process, so mini piles will be the better alternative because of the lack of noise and minimal vibration they've created. Hence, it's suitable for construction projects near or inside the vicinity of residential areas, hospitals, schools, and other places where a lot of noise can be disruptive.

Seasoned piling contractors can install mini piles. They recommend piling when the structure requires steady support, specially when being internal urban areas or on soil which has a weak surface. Timber subfloor piling contractors use suspended auger and hydraulic-driven mounted systems to push cylinders in the ground to get a quick and efficient job. Be sure to engage a piling contractor that understands the ground conditions locally.
