Prior to Christmas 2022, we broke ground.
Rather than installing a traditional concrete slab, we opted for an alternative with a much lower carbon footprint and a lighter impact on the site.
To avoid concrete entirely, we chose a footing system manufactured by Mega Anchor.
These steel foundations utilise three rods per footing, which are jackhammered into the ground at opposing angles to form a stable tripod.
Because these foundations are significantly stronger than traditional concrete stumps, we were able to increase the span between them to 2.4 meters, nearly doubling the conventional 1.2 to 1.8-meter spacing. This essentially halved the total number of footings required for the project.
Our block sits on a layer of sandstone bedrock at a depth of about 900mm. Once the steel rods struck this bedrock, the excess length was cut off.
Thanks to this tripod configuration resting directly on solid rock, the foundations are completely immovable, even in wet conditions.
Directly onto these footings, we laminated two 190x45mm H3 MGP10 timbers together to serve as the bearers for the flooring.
