Mini piles have lower capacity than bored piles. Therefore; they are used to transport lower grade of vertical loads. Mini piles are 25-30 cm diameter of pile applications. 15m. These pipes can be used in deep anchoring applications and underground ground improvements. After drilling with a piling machine, the iron reinforcement is lowered to the well and the concrete is cast, and the application is completed. The elevation of the groundwater level can affect the casting of concrete. To avoid this, the injection hose is added to the system and concrete-cement grout is added instead of concrete.
