Pinpiles or Minipiles
 
Pin pile or mini pile with two compressive and tensile performances refers to casted-in-place piles with diameter of 250 mm and with the maximum length of 30 meters. These elements have been widely used in many construction projects during the past half century. The main purpose of the pin pile application is controlling settlement. Pin piles are applicable in most soils and they have acceptable bearing capacity. This method is particularly valuable when the soil layers are variable and surrounding buildings are sensitive to vibrations. The standard method of making pin piles consist of 4steps; (1) excavation and if necessary casing installation, (2) installation of reinforcement elements, (3) cement grout injection with casing removal.
