Traditional House Pile Foundation
Description

StopDigging provide a CodeMark certified groundscrew pile foundation system, that works as a cantilever pile foundation for lightweight and low rise buildings.

StopDigging's bespoke Design and Installation Declaration process allows easy specification and consenting.

Key Features
  • Codemark certified for an LBP Designer to specify within the scope of the Design Guide without further engineering costs
  • Groundscrews are the most efficient piling solution available due to speed of installation and instant load bearing capacities
  • Stopdigging provide onsite, static pile testing as formal verification for each project, which also eliminates the risk of on site variations
  • A Groundscrew foundation eliminates ground disturbance, and creates zero site waste allowing a massive increase in productivity onsite compared to traditional methods
  • Groundscrews are available in a wide variety of diameters, lengths and types to provide a solution for almost all ground conditions evident in NZ
  • The groundscrews system is highly sustainable and offers a lower carbon footprint than any other method
  • Groundscrews are designed as a permanent foundation solution, however they can easily be removed and re-used allowing them to be a perfect solution for temporary transportable buildings

Scope of Use

Groundscrews are suitable for all types of house piling either within the scope of NZ3604 or with structures that have specifically engineered design.

They are suitable for  low rise structures, lightweight transportable and modular buildings and traditional built on site construction methods.

They are suitable for use in most TC2 and TC3 ground classification with appropriate structural design to suit the site specific requirements.

Groundscrews work as a single, or grouped cantilever pile system and can also be used as a spot footing for pile extensions and posts.

The specification of the StopDigging groundscrew system has been simplified as part of the CodeMark accreditation, and has removed the need for producer statements.

The StopDigging groundscrew system is specified by an LBP Designer for projects within the scope of our Design Guide, without further structural engineering input.

An LBP Designer needs to simply provide pile design loads and a connection detail on the subfloor plan - these are taken from the table in Appendix 2 of our Design Guide for structures within  this scope. ( 3604/Nash)

For all other types of buildings, a CPEng will provide a pile design load calculation package based on the structure, and the Designer will include this in the documentation.

The Designer or Engineer provides a completed Design Declaration form as part of a building consent application. StopDigging provide an Installation Declaration and formal pile test report on completion of the foundation.

 

Limitations on Use

Where ground conditions are subject to liquefaction potential or slope stability issues, a CPEng needs to provide a pile design load specification in conjunction with the recommendations of the geotechnical report.

Groundscrews are not suitable for use in solid basalt/granite bedrock, but softer rock like sandstone/mudstone is suitable with appropriate pilot drilling.

Groundscrews are not suitable for founding into soft organic material/peat as a load bearing strata, but can be used to pile through into stable ground below.
