Piling or Piering

The term piling or piering is a way of making foundations in sand or unstable ground, every third hole is drilled out by hand to the required depth, a steel cage is lowered into the hole and the hole is pumped with concrete creating a solid concrete reinforced column to rock or the engineers required depth.

Our team of hand piling experts in Sydney will then repeat this process 2 more times, creating a straight wall called contiguous piling that can then be excavated. These piles can be used as foundations or retaining walls to create a space for under ground car parks, garages, basements or to house swimming pools. Most walls have a capping beamed formed on top of the piles that adds further strength and offers a level platform for additional construction. We can drill piles in sizes of 300mm, 400 mm, 450mm and 600mm in diameter and up to a maximum depth of 12 meters.
