What is Mini Piling and Why is It Important?
Piling helps ensure a sturdy foundation with the installation of heavy posts or stakes within the subsurface. T here are several types of deep foundation piling, along with the micropile is one of them. Known as 'mini piling', micropiles are deep foundations designed with heavy-duty steel casings and/or threaded bars that are small in diameter, usually three to 10 inches. The casing is installed by using a specialised drilling equipment and method. An all-thread bar is reinforcing steel in mini piling, which is often inserted in to the casing of the micropile. The capacities are vastly different with regards to the profile from the subsurface along with the size in the micropile. Mini piling has been used effectively on structures with capacities exceeding 1,000 tonnes.

Mini piles was once applied only on certain ground conditions because of factors like speed and cost. Without proper equipment, mini piling is slow and tedious on account of the flushing and drilling processes associated with it, resulting inside job possibly taking hours being accomplished. However, technological advancements in equipment, machinery, and technique are making mini piling popular in more applications, especially when the development project must comply with low vibration and no-noise regulations, that are common in congested environments like urban areas.

Geotechnically speaking, mini piling makes sense in ground conditions like shallow bedrock, intermediate hard strata, underpinning, cavities and boulders. Concrete piles like reinforced concrete square and spun piles can produce a lot of noise through the driving process, so mini piles will be the better alternative due to the lack of noise and minimal vibration they've created. Hence, it really is perfect for construction projects near or from the vicinity of residential areas, hospitals, schools, as well as other places where excessive noise may be disruptive.

Seasoned piling contractors can install mini piles. They recommend piling if your structure requires steady support, especially when being internal urban areas or on soil with a weak surface. Reputable piling contractors use suspended auger and hydraulic-driven mounted systems to push cylinders in the ground for the quick and efficient job. Be sure to work with a piling contractor that understands the bottom conditions locally.
