Top 10 Advantages of Contiguous Pile Walls

The Top 10 Advantages of choosing a Contiguous Pile Wall are:
  1. Easier to build in load variations, with no requirement for a guidewall
  2. It’s a cost-effective bored pile solution, compared to Diaphragm walls
  3. They can be used for more flexible geometry than a diaphragm wall
  4. Load bearing capacity
  5. Can be installed in difficult ground conditions
  6. Contiguous Walls are ideal for metropolitan cities. (Urbanisation makes the cost of land high and so it is increasingly common to go deeper into the ground)
  7. CFA piles are considered more economical than diaphragm walls in small to medium scale excavations due to reduction in cost and time of site operations
  8. Contiguous piles are suitable in crowded urban areas, where traditional retaining methods would otherwise encroach the adjoining properties
  9. The presence of footings of adjacent buildings and underground utilities on a site make contiguous pile wall the ideal choice for supporting an excavation
  10. Contiguous piled walls have a faster speed of installation when compared with secant piled walls

Contiguous pile walls are mainly constructed using the CFA technology and consist of reinforced piles (soft – reinforcement cage; firm – steel section). Contiguous piled walls are utilised when groundwater ingress is not an issue. The dimension of the gap between the piles typically ranges between 50 and 150mm. A permanent wall can be created, taking the form of a structural concrete facing wall tied to the piles or sprayed concrete. A contiguous pile wall is the ideal choice of earth retention systems in the urban context.
