Fence
Replacing a fence destroyed by Gabrielle. First ground screws for the fence posts and then assembling the fence.
High deck, solar array and cabins
The project was to set up the foundations for a few additions (solar array, deck & 2 cabins) around a large relocatable house. Nice project in a surprisingly difficult ground, including boulders underneath. Ground screws delivered their promise!
Kitset cabin on sloping ground!
A friend wanted to install a kit set cabin in his back yard. Although the ground had a steep slope, ground screws came to the rescue.
Homestead installation and relocation
We first installed the foundation for a tiny house, shed and decks in 2022...and relocated the whole homestead in 2024! Every screw was reused. No waste.
Cabin piles
Installing ground screws for a cabin. It is always important to know the load capacity of the screws in the ground. We conduct a load test to determine it exactly.

I really appreciated the work that Thibaud and Tiko did for me in putting in ground screws for my cabin and inserting screws and tie downs for my tiny home. I feel a lot more secure, especially in this current spate of horrendous wind and rain. Equally importantly, I appreciated Thibaud's communication; getting back to me straight away to answer questions, listening to any concerns I might have had, and making suggestions about what would work best. It's challenging enough trying to manage a project and having other tradespeople who didn't get back to me (sometimes at all!) makes it even more difficult. Thanks for being the Good Guys. Reply: Many thanks Stephanie.

I would highly recommend Ground NZ to anyone requiring ground screw installation. Thibaud was meticulous in his planning, and then careful and effective in the execution, resulting in a very satisfactory outcome for us. Thibaud is obviously very experienced, and his friendly demeanour and willingness to discuss details made working with him easy and pleasant. Reply: Thank you for the kind words Andrew!

What lovely people, their communication and interaction was nothing but professional, friendly and informative. An absolute delight and nothing was too much trouble. Cant wait for our tiny home to arrive and get put onto the screw piles they did for us. Reply: Thank you Heather for your kind words.
