Services
From a dozen ground screws for a deck to a full house foundation with engineering and producer statements, one team takes care of it from Takanini.
Our rig and crew install every pile to target torque, cut to level and fit the heads. Most jobs take a day or less, and your builder can start straight after.
For consented builds we organise a chartered engineer to design the pile layout and target torque (PS1), then provide our PS3 with the torque record. Already have an engineer? We'll work to their design.
When the engineer wants proof beyond the torque correlation, we can arrange on-site load testing of a sample of piles before or after installation.
Ground screws, extensions, saddles, plates and bracket kits for builders and DIYers. Pick up from Takanini or we'll deliver. Send us your plan and we'll put the list together.
Applications
Most timber-floored houses can sit on screw piles instead of bored concrete piles. Your engineer (or ours) designs the layout and target torque, we install and log every pile, and the builder starts the subfloor the same day. It's especially worth it on soft, wet or sloping sites, where digging holes is slow and messy.
Additions are often squeezed against the existing house, with tight side access and nowhere to put spoil. The compact rig gets through a side gate, the piles go in beside existing foundations without undermining them, and there's no concrete truck in the driveway.
We install the piles to the layout before the house arrives, so it can be craned or rolled straight on. If the building moves again one day, the piles unscrew, with no concrete left behind.
Small standalone homes up to 70m² are what our sister company Hari Tiny Homes builds every week. Screw piles suit them perfectly: quick to install, easy to level, and removable. We can pile any brand of tiny home or granny flat, not just Hari's.
A typical deck's ground screws go in in a morning, and the builder can start framing straight after. They come supply-only for builders and confident DIYers, or installed by us.
Garden sheds, sleepouts, studios and cabins: a set of ground screws or helical piles gives a dead-level base on sloping or soggy ground, without boxing, pouring or waiting.
Heavier piles with cap plates for steel portal frames, canopies, carports and light commercial buildings, including Kiwi Steel Frames builds. Every one is a specific design, with load testing available.
Fence and gate posts, signs, flagpoles and ground-mounted solar arrays. Ground screws are quick to line up, carry wind uplift well, and don't leave concrete in the ground when things change.
Helical piles can carry retaining wall posts, and can underpin existing foundations that have settled, with minimal digging next to the building. These are always engineer-led, so talk to us early.
Where we work
Our rigs leave from the yard at 182 Great South Road, Takanini, just off the Southern Motorway. That puts most of Auckland, Waikato and the Bay of Plenty within a morning's drive. Further afield? Ask, especially for larger jobs.
