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.

Ashley Bartley
I recently hired Grounded NZ to install screw piles for the deck flooring within a Marquee at the wedding venue I run, and I couldn't be more pleased with the results. The entire process was smooth and efficient from start to finish. The team arrived punctually and worked diligently to complete the installation in a timely manner. They demonstrated a high level of professionalism and expertise throughout, ensuring that the screw piles were installed securely and according to specifications, even with a few tricky aspects I threw at them. Communication with Thibaud Lastennet was excellent; he was responsive to my questions and kept me informed at every stage of the project. Overall, I'm extremely satisfied with the quality of workmanship and the level of service provided by Grounded NZ. I would highly recommend them to anyone looking for reliable and skilled contractors for screw pile installations. Reply: Thank you Ashley! I hope your deck sees a lot of merry people getting married and dancing on it!

I recently used the Grounded system of ground screws for two large public sculpture exhibitions, one in Hamilton and one in Waiheke. I need screws which can be easily levelled and which will ensure the sculpture is stable and safe from humans and high winds.Thibaud installed the screws in Hamilton in what turned out to be difficult teraain, and I was impressed by how thorugh and commited he was to providing an excellent service. On Waiheke I hired the driver and installed the screws with the assistance of an installation team. Both sculptures can now be easily removed at the end of the exhibitions and easily re-positioned in new situations. Reply: Thank you Natalie, it was a fun and unusual job.

Highly recommended. Thibaud was great at explaining the process, discussing options and being very clear about what our situation would require. Great knowledge and very helpful. When our ground tried its best to give us challenges he was easily available on the phone with solutions. Communication was excellent. Very happy with the whole process. Reply: Thank you Andrew and I am quite glad that your perseverance paid off. Good luck with the rest of the project.

My husband and I are very happy with Grounded NZ. Thibaud visited our site and we felt that he really understood what we wanted to achieve with our deck and solar ground mount. We received a detailed quote the same evening. The team worked efficiently and with precision (quite fascinating to watch) and finished all the work in one day. Reply: Hi Maria, thank you for the review. We certainly try to respond quickly, do just what is needed, using our screws or someone else's.
