  • *Shallow Foundations~ for transferring building loads to underlying ground~ mostly for firm soils or light loads

    *

  • *Deep FoundationsPILE~ for transferring building loads to underlying ground~ mostly for weak soils or heavy loads

  • *EarthworksRoadwork, Pacific Highway~ preparing the ground prior to construction

  • *Sheet Piles~ sheets of interlocking steel or timber driven into the ground, forming a continuous sheet

    *

  • *Sheet Piles~ used in temporary works

    *

  • *Cofferdam~ sheet pile walls enclosing an area, to prevent water seeping in

    *Cofferdams are often used in temporary works, to enclose the construction area within a continuous sheet pile wall around and protect it from water entering from outside.
