What is a Screw Piers Concreter?

A Screw Piers Concretor is a qualified concreter or subcontractor who installs screw pier foundations — deep, steel piers that are mechanically screwed into the ground to support your structure. Screw piers are commonly used on reactive or sloped sites where extra foundation stability is needed.



Unlike traditional bored piers, screw piers can be installed without excavation and provide immediate load-bearing capacity, making them ideal for faster site progress.

What does a Screw Piers Concreter do?

Your Screw Piers Concreter will complete works according to your agreed scope of works.


Typically, a Screw Piers Concreter will:

  • Review engineering documentation and site conditions
  • Accurately mark out pier locations using survey data
  • Supply and install screw piers to required depths and torque levels
  • Coordinate with your builder or engineer to confirm final set-out
  • Provide certification or compliance documentation for installed piers


They may also assist in coordinating inspections if required by your certifier.

Tip: Allow for Pier Depth Variations and Double-Check Alignment

If your pier depth isn’t fixed in the plans, allow for variation in your quote — reactive clay soils can increase the number or length of screw piers needed.


Make sure your surveyor or builder is on-site for final alignment. Misaligned piers can throw off your whole slab layout.

What to look for in a Screw Piers Concreter

When reviewing quotes, look for:

  • Experience working with residential screw pier systems
  • Availability to complete works in line with your slab timeline
  • Clear quote terms for pier depth, inclusions, and machine access
  • Compliance with engineering and Australian StandardsAbility to provide certification post-installation

Before You Begin: What You’ll Need Ready

To get quotes from Screw Piers Concreters, you’ll need:

  • Engineering plans and pier schedule (or soil report)
  • Site survey and set-out plan
  • Access instructions and any restrictions on machinery
  • Target date for installation
  • Confirmation on whether you or the builder will manage site levels

Average Timeframe

For this task, Pros typically provide quotes within 7-10 business days.

When Can I Expect Quotes?

Timeframes often vary based on demand and the type of Pro you're engaging (e.g. a plumber). If additional communication or clarification is needed is needed, the quoting process may take longer.

 

Don't be alarmed if you don't receive quotes or communication from any Build Buddy Pros straight away. Some work is more complex and the Pro may need time to comprehend your documents or scope of work. Depending on the job, there may even be some work required by the Pro before they are able to quote (e.g. a site visit might be required).

 

If the average timeframe indicated here has passed, and you have not received any messages or quotes, please feel free to contact the Build Buddy Expert Guidance and Support team for an update on quoting for this task.

Frequently Asked Questions

  • Why use screw piers instead of bored concrete piers?

    Screw piers are quicker to install, don’t require excavation, and reduce mess on-site. They’re ideal for reactive soils or where fast load-bearing capacity is needed.
