Piling or piering is a method of creating a foundation for a structure in sandy or unstable ground by creating reinforced, solid concrete columns that reach down to the bedrock or nominated depth.

These piles/piers can be spaced according to an engineer's specification or in a line to form a barrier or structural support, which is called contiguous piling. Normally a concrete beam is formed along the top of the piles and is referred to as a capping beam, which adds further structural integrity to the system and can offer a platform for further structural construction.
