The work
Earth Stability was approached to provide a design and build solution following a land slip on this steep residential site. This was a lump sum project, awarded to Earth Stability through competitive tender amongst invited specialist tenderers.
The project involved the construction of a 19m long tied-back timber pole retaining wall, drilled horizontal drains, the installation of tie-back anchors, the installation of steel waling beams and earthworks.
This was an extremely steep site with highly restricted access. All plant and materials were mobilised to site by hand, including each of the 500kg timber poles that had to be winched up the slope and carefully lowered into position.
In addition to the main slip repair works, Earth Stability was awarded the pile construction works for a new extension and renovation to the property using its man-portable piling rig. The site sits near the top of Mt Atkinson in Titirangi, covered in dense protected native bush requiring compliance with very strict consent conditions, all of which were met throughout the works.
