Screw pile foundations, installed in a day.

Engineered steel screw piles for houses, decks, tiny homes and sheds. No digging, no concrete trucks and nothing to cure, so you can build on them the same day.

Why screw piles

Everything good about a foundation, without the hole.

A screw pile is a steel shaft with helix plates near the tip, screwed into the ground until it reaches firm soil. It does the same job as a bored concrete pile, minus the digging, the mess and the wait.

  • Build the same day

    Nothing to cure. Piles carry load the moment they're in, so framing can start that afternoon.

  • No digging, no spoil

    No holes, no muck to cart away and no wrecked lawn. A small rig and a crew of two.

  • Rain or shine

    No holes to flood and no pour to postpone. Wet weather rarely stops an install.

  • Slopes & soft ground

    Bolt-on extensions take piles down to firm ground. No benching, no boxing.

  • Every pile verified

    Installation torque shows what each pile can carry, and we log it pile by pile for the engineer.

  • Removable & reusable

    They unscrew the way they went in, leaving no lump of concrete behind.

Pile estimator

How many piles will you need?

Pick what you're building and drag the size. You'll see the pile layout and how long we'd be on site, live. The full estimator adds ground and access, and sends the result to us for a quote.

How it works

Five steps from enquiry to building on it.

  1. 1

    Tell us about it

    Call, email or send your estimate. Plans help, but a sketch with dimensions is fine to start.

  2. 2

    Site check

    We look at access, ground and underground services, and confirm the right pile for the job.

  3. 3

    Engineering

    For consented work, the engineer designs the layout and target torque and issues a PS1.

  4. 4

    Install day

    Set-out, then each pile screwed to target torque and cut to level, with depth and torque logged.

  5. 5

    Handover

    The torque record and PS3 go to you and the engineer, and your builder starts straight away.

One yard, the whole build

From the ground up, on Great South Road.

Kiwi Screw Piles shares a yard and a team with Kiwi Steel Frames, Hari Tiny Homes and Pro Windows & Doors. So the piles, the frame, the home and the joinery can all come from people who work together every day, with one point of contact and nothing lost between trades.

Questions

The things people ask first.

All questions
What is a screw pile?

A steel shaft with one or more helix plates near the tip, screwed into the ground by a hydraulic drive head on a digger. The helix plates bear on the soil like the threads of a screw in timber, so the pile carries load as soon as it is in.

Ground screws are the lighter version: a tapered shaft threaded along its length, used for decks, fences, sheds and similar.

Can you build on them straight away?

Yes. Nothing has to cure. Once a pile is in and capped it can take load, so the builder can start on the bearers the same afternoon.

How long does installation take?

A deck or shed usually takes a few hours. A typical house or relocated home takes a day or two, depending on the number of piles, the ground and access. The estimator gives a rough figure for your project.

Are screw piles cheaper than concrete?

Often, once you count everything: no digging, no spoil to cart away, no concrete truck or pump, and no days lost waiting for concrete to cure or holes to stop filling with water. On easy, firm sites concrete can still come out cheaper. We'll tell you honestly which is better for yours.

How do you know each pile is strong enough?

There is a well-established relationship between the torque it takes to screw a pile in and the load it can carry. We record the depth and final torque of every pile and give that record to the engineer, who compares it with the design target. If a pile doesn't reach target torque, we keep going deeper with an extension.

For larger jobs we can also arrange on-site load testing.
