Bored Piled Retaining Walls2017-06-22T07:55:22+00:00

Project Description

Contiguous Piled Wall

Contiguous piled retaining walls are formed using either Rotary or CFA piling technics, piles are installed at close centres, with typically 100-200mm gaps between piles. These piles form temporary or permanent support to excavations. This techniques is suitable for basements, underground structures and motorway cuttings where working space is limited or adjacent to existing structures.

Secant Piled Wall

Secant piled retaining walls are formed using either Rotary or CFA piling technics, unreinforced female piles are installed at close centres using a slow-gain (soft) concrete mix, after a sufficient curing period and once each alternate pile has been installed, the reinforced male piles are installed using a standard concrete mix. The overlap for a typical secant section is approximately 75 – 100mm which ensures that water ingress is minimised and fines wash-out is prevented. The interlocking secant wall is not watertight; however water flow is greatly reduced. These piles form temporary or permanent support to excavations. This techniques is suitable for basements, underground structures and motorway cuttings where working space is limited or adjacent to existing structures.
