Groundscrew Underslab Piling
Stopdigging Groundscrews can be used as an alternative to a deepened perimeter footing or cantilevered raft slab design as a ground improvement method in expansive ground, or ground with poor bearing cpacity.
The ground screws extend beyond the influence of the shrink-swell zone and support the slab edge in the event of shrinking soil, or through soft ground into higher capacity soils below.
There are also used to efficiently create bridging over buried services and zone of influence mitigation of retaining walls.

About the
Seller
Groundscrews allow installation of a pile foundation in a fraction of the time it takes with other piling methods.
How do you use our Groundscrews?
Our CodeMark certification allows a simple design process for building consent.
They are an anchor pile to NZ3604. Standard subfloor design is all that is required. For projects outside of 3604, we have multiple design options for cantilever piles, and spot footings with load bearing capacity up to around 150kN, and larger by special order.
We provide a full specification and installation service, including site specific static pile testing, reports and CodeMark declaration for Building Consent.
For large scale developments, small one off houses and decks, or civil engineering projects, especially in areas with sensitive environmental considerations or limited access, the use of StopDigging! groundscrews will massively impact your construction timeline - for the better:
No spoil / mess to clear up.
No excavation inspections.
No weather delays.
Zero construction waste for foundations.
Lower carbon footprint than concrete.
