Description
Cast-in-Place Piles (also known as bored piles or drilled shafts) are deep foundation elements constructed by drilling a hole into the ground and then filling it with reinforced concrete on site. They are widely used in construction and infrastructure projects where high load-bearing capacity and ground stability are required.
In photovoltaic (PV) and structural applications, Cast-in-Place Piles provide a solid and permanent foundation for mounting systems, especially in areas with complex soil conditions or where driven piles are not suitable.
