Foundation specification
for permanent property poles

Every permanent pole order includes a hot-dip galvanised foundation cage delivered ready to place — your concreter pours the certified footing around it. Below: bore depths, bolt PCDs, reinforcement and concrete grade for both 1 kN and 3.5 kN poles, straight from the RPEQ-certified drawings.

Pick your pole rating

Toggle between the 1 kN and 3.5 kN specifications. The two poles have different bore depths, baseplate sizes, bolt patterns and PCDs — make sure your concreter is pouring for the rating that matches your order.

Soil & site conditions

The certified footing assumes standard soil conditions ≥ 150 kPa bearing capacity in Wind Region C, Terrain Category 2.5. Reactive clay, uncontrolled fill, sloping sites or unusually exposed locations require a site-specific geotechnical report and engineering certification. Call us on (07) 3367 2237 before you pour if you're unsure.

Builder checklist

Nine steps from confirming the pole location to handing the site over for installation. Tick these off and you'll be ready for our crew on day one.

  1. 1

    Confirm pole location & rating

    Verify the position with the site plan and confirm whether the pole is 1 kN or 3.5 kN. The two ratings have different bore depths, bolt patterns and PCDs — they are not interchangeable.

  2. 2

    Dial Before You Dig (1100)

    Confirm there are no underground services in the excavation zone before drilling.

  3. 3

    Excavate the bore

    Ø 450 mm hole drilled to the certified depth for your pole height (see spec above). Hole must be vertical and free of loose material.

  4. 4

    Place the foundation cage included with your order

    Every Poles & Holes permanent pole order includes a hot-dip galvanised reinforcement cage (Tempcore Y-bars + R8 hoops @ 300 CTS) with the cast-in bolts pre-set on the certified PCD and a position template at the top. 1 kN: 4 × M20 on 233 PCD. 3.5 kN: 4 × M24 on 280 PCD. Centre and plumb the cage in the bore. Maintain 75 mm minimum cover to all faces. Brace the position template to hold everything square during the pour.

  5. 5

    Pour min 32 MPa reinforced concrete around the cage

    Fill to full depth with min 32 MPa premix. Rod to remove air pockets. Slope the top to drain. The bolts should project enough that 2 threads minimum extend above the upper holding nuts after the pole is set.

  6. 6

    Cure for a minimum of 48 hours

    Do not disturb. Protect from extreme heat or rain. Installing on uncured concrete will void the structural warranty.

  7. 7

    Remove the position template

    Once the concrete has cured, remove the position template that held the bolts square. The bolts stay cast into the concrete; the template lifts off.

  8. 8

    Keep the area clear for crane access

    Remove spoil, tools and obstructions. Confirm crane truck access on installation day.

  9. 9

    Notify Poles & Holes

    Contact us once the footing has cured to schedule the pole install. Send a photo of the completed foundation.

Frequently asked questions

The questions builders, concreters and site managers ask us most often about pouring for our property poles.

What if my soil is below 150 kPa bearing capacity?
The certified specification is valid for soils with a bearing capacity of at least 150 kPa. If your site has reactive clay, fill, or other poor soil conditions, you'll need a site-specific geotechnical report and engineering certification — call us before you pour and we'll arrange the right path forward.
Can I substitute a lower concrete strength like 25 MPa?
No. The footing is certified at a minimum of 32 MPa reinforced concrete with the specified Y-bar / R8 reo cage. Substituting a lower grade voids the engineering certification, the structural warranty, and may fail an Energex inspection.
Where does the foundation cage and bolts come from?
Every Poles & Holes permanent pole order includes a hot-dip galvanised foundation cage delivered ready to place. The cage comes with the cast-in bolts pre-set on the certified PCD (4 × M20 for 1 kN, 4 × M24 for 3.5 kN), 2 nuts and washers per bolt, and a position template that holds the bolts square during the pour. Your concreter places it in the bore and pours the concrete around it — no sourcing or fabrication required on your end.
Do the dimensions in the diagrams match the certified drawings?
Yes. The bore diameter, depths, baseplate sizes, PCDs and bolt sizes shown on this page are taken directly from the RPEQ-certified drawings (refs P13023/CL4 for the 1 kN and P13023/CL5 for the 3.5 kN) signed by Peak Construction Engineering, RPEQ 8999, on 19 May 2021. Download the certified packs above for the originals.
How long after the pour can you install the pole?
Minimum 48-hour cure. We recommend booking the install for 3–5 days after the pour to be safe. Send us a photo of the completed footing when you book.
What about wind region and exposure?
The structural certification covers Wind Region C, Terrain Category 2.5 — which suits the vast majority of South East Queensland sites. Coastal exposure pockets or unusually exposed sites may need a site-specific check; call us if you're unsure.
What you actually buy

Everything bundled into a Poles & Holes order

Going direct to a fabricator gets you a pole. Going to Poles & Holes gets you a finished, energised installation — fixed-price, fully certified, with all the Energex paperwork handled.

Foundation cage delivered ready to place

Hot-dip galvanised cage with cast-in bolts pre-set on the certified PCD and position template — your concreter just drops it in and pours.

Crane installation by our licensed crew

Our team arrives with the truck, crane and equipment, positions the pole on your cured footing and tightens to the certified torque. No coordination on your side.

Energex Connect Application + EWR

We lodge the Connect Application and Electrical Work Request with Energex on your behalf, schedule the meter and connection, and chase the network for you.

Certificate of Compliance (CCEW)

Licensed electrical contractor sign-off — the certificate you need for council, insurance and re-energisation. Filed and copies sent to you.

Fixed price + warranty

One quote, no surprises. Backed by structural certification, our installer warranty and 24/7 emergency callout for defect rectification across SE QLD.
