B.1 Solider Piles Walls
Installation of the soldier piles ( sometimes two back-to-back C-channels are used
as a soldier pile) is undertaken by means of rotary drilling to the required level, then
installing the reinforcement and concrete of the soldier pile( or the two back-to-back
C-channels ).
The bulk-excavation process is executed in layers, to allow for the lagging panels
(timber/ R.C slabs) installation at the same time during excavation.

B.1 Secant Piles Walls
The demand for efficient and economic retaining walls solutions has significantly
increased during the past few years. With the varying conditions of adjacent soils /
structures, the secant piles walls can be considered as one of the best solutions to
handle/overcome such variance. The secant piles wall consists of two types of
piles:
• Primary piles: which are rotary drilled to the required level, but poured with plastic concrete (a mix of plain concrete and bentonite slurry), and no reinforcement is used.
• Secondary piles: which are rotary drilled to the required level (cutting through the edges of the primary piles), then installation of reinforcement and pouring of concrete is carried out in the same way as bored piles.
