Mini Piling
IOTA provides mini piling using piles with a narrow diameter to strengthen excavation walls. This makes them light and inexpensive, but still able to support a considerable load.
For the most common type of mini piling, a hollow steel or plastic shaft is either screwed or drilled into the ground. Grout or concrete can then be poured in to form the pile, with the soil supported throughout by the steel shaft. This means that, unlike the traditional boring method, no extra supports are needed, even in weak soil.
Alternatively, especially if there’s limited headroom, sectional auger mini piles can be used. This involves boring down and adding multiple flight sections as you go. Depending on the soil’s stability, the sections can either be removed or left in place while pouring the concrete in.
Mmini piling has advantages in many situations including cases where the piling has to be carried out in a confined space, since the equipment is significantly smaller than what’s required for traditional piling. It’s also good for built-up areas, since it causes less noise and vibrations, while still producing secure foundations.
