Some of the most beautiful sites in New Zealand come with their own set of challenges — and this project in Diamond Harbour, Christchurch was no exception.
Our client had a dream: to place a Genuine Tiny Home on a steep, rocky section with a spectacular view. The location was perfect — but it came with tricky access, solid rock, and no possibility of getting heavy machinery onto the site.
That’s where our team from Wildboar Footings and our install team from Helix Global Limited stepped in.
Using a combination of S250 and S400 footings, the installers were able to overcome the site’s toughest challenges. The tallest part of the foundation reached an impressive 4.7 meters — fully secured and braced — providing a rock-solid platform without a single drop of concrete required.
Even in hard rock (pre-drilling was required) and on steep terrain, the footing system performed exactly as designed. The client was thrilled to see how clean and efficient the process was — no mess, no delays, and no risk of failure.
It’s another great example of how versatile and proven Wildboar Footings are, giving builders and homeowners the freedom to build on land that others might walk away from.
If you’re dealing with a challenging site — steep, rocky, remote — we’d love to help you do the same.
Wildboar Concrete Free Footings are fully compliant with the NZ building code and are a great alternative to screw pile and concrete. Unlike screw piles a builder can install themselves with no special equipment required, saving time and money. No need to wait for a special installer to come out to site.
With over 250,000 feet installed across Australasia our products are tried and tested. Add to this 5 years worth of paid research and onsite validation testing by the structural teams at Melbourne and Swinburne Universities
Our footings will go in anything from solid rock to soft sand and we have solutions to suit small decks to large multi story buildings. Our foot capacities range from 4kN to 500kN
Wildboar Footings in the only licensed distributor of Surefoot products in the South Pacific. With a network of engineers and installers throughout New Zealand and the Pacific we can offer a full turn key service for foundations from Tiny homes up to Multi story buildings.
We are backed by Surefoot Australia who own all patents and intellectual property globally allowing us full access to the engineering and development team based in Melbourne.
Unlike Screw piles we can install into almost any ground condition from soft sand to hard rock. Making our foundations a very cost effective solution.
The Surefoot concrete free footing system is an “all-in-one system”, where a unique shape and high-strength steel combine to create an efficient pile cap. Once the piles have been driven, and the cap has been secured, the opposing forces of the multi-directional piles provide a stable, robust and economical footing.
The Surefoot system is designed to increase efficiency when resisting uplift, gravity, shear and moment loads. The soil structure ultimately absorbs the applied stress. This footing system is job specific, meaning it will be designed according to your particular site soil conditions, structural design loads etc.
The Surefoot footing system cannot be labelled as either a shallow or deep footing and therefore belongs to a new “hybrid” category of footing.
