Bored piling is a method of construction which utilises reinforced concrete piles to support high buildings bearing heavy vertical loads. Bored piling can be applied to a wide range of ground conditions and is often used to overcome unstable or difficult soil strata.
In addition to providing foundation piles, retaining walls and earth retention systems can be formed using the bored piling method. Such retaining walls may be either Contiguous or Secant. A contiguous wall is formed by installing closely spaced bored piles, with a small gap between adjacent piles. In contrast, a secant pile wall is formed by installing overlapping bored piles where water tightness is a requirement.
We have rigs which can install secant piled or contiguous piled walls within 100 mm of an adjacent structure. This is particularly of interest to basement schemes where every square foot of extra space adds value to the client. These rigs can work in any strength of soils and after the retaining walls are installed can also drill the foundation piles for the project.
