This Park Road project had the potential to become a builder’s nightmare, with its steeply sloping site and construction over three levels. Access was difficult and two diggers were required to prepare platforms for construction of a pole house.
The design called for ‘extreme piling’ in the form of spiral cages with tana-pole piles inserted within the spiral.
The builder had come across Conqra’s Eziyaka pre-cast pads at a building merchant, and he contacted us for advice. We determined that Eziyaka pads could provide a strong base for the pole and cage alignment. Secure foundations could be easily created by placing the Eziyaka pads in the excavation before installing the steel cage and inserting the pile.
There were major cost and time savings through eliminating wet concrete and concrete pumps from the process. Using Eziyaka enabled the builder to align the foundations within one day, instead of the three days required for wet concrete and pumps. There was no need to engage a separate subcontractor and arrange delivery of a concrete truck on a site with difficult access.
The builder and homeowner were thrilled by the efficiency of the process and the quality of the result. The builder has since gone on to use Conqra products on dozens of further projects, including retaining walls and re-piling jobs as well as new house builds.
