Ground Screws

Deck Foundations in Auckland — Without Concrete

Building a deck should be exciting — not slowed down by digging holes, pouring concrete, and waiting days for it to cure.

5 Frequently asked
‍questions

Yes. Ground screws are engineered load-bearing foundation systems designed to support residential and light commercial structures. When correctly specified and installed, they provide excellent vertical and lateral stability for decking projects.

Ground screws are widely used in New Zealand and internationally. Compliance depends on correct application, design, and installation. BaseDrive works within accepted construction practices and can coordinate with builders or designers as required.

Significantly. Most deck foundations using ground screws can be installed in a single visit, with no waiting time before construction starts. There is no curing period, which can shave days off a project timeline.

Ground screws can be removed or reused in many cases. Unlike concrete piles, they don’t permanently scar the ground — making them a more flexible and environmentally considerate option.

Upfront costs can be comparable depending on the site. However, when you factor in reduced labour, no excavation, no concrete pours, no curing delays, and faster build times, many homeowners find ground screws offer better overall value.
