Piling foundations in Aukland are a type of deep foundation used in structures and buildings that require extra support. They are built by inserting piles, often made out of concrete or steel, deep into the ground to form a stable base for the structure above. Piling foundations provide stability against natural forces such as earthquakes, wind and soil erosion and help to spread the weight of loads imposed by the structure evenly across the ground. As piling foundations penetrate deeper than shallow foundations, they enable heavier loads to be supported and also help to protect against water ingress. Piling foundations can be installed using various methods including driven piles which are hammered into the ground; drilled shafts which use a drilling machine; or pressed piles which use hydraulic pressure to push them into place. The choice of method depends on factors like site conditions, cost and environmental requirements.
