An unfilled underground tank doesn’t stay put. Over time the void shifts, the ground above compresses, and you end up with cracked driveways, sunken garden beds, or worse, a property that fails inspection. We’ve seen it enough times to know it’s not a problem worth deferring.

Our team handles backfilling of decommissioned fuel tanks, rainwater tanks, and old septic structures across residential and commercial properties. We have the right materials for the specific job, compact it correctly, and provide documentation where required. 

Why Choose Us

  • Fill Material That Actually Suits the Job: Flowable fill, compacted gravel, engineered soil; we choose based on what the tank and surrounding ground actually needs, not what is easiest for us.
  • Compliance Sorted: Council and environmental requirements for decommissioned tanks surprise many people. We know what’s involved and make sure the work ticks every box, including paperwork for sales or development.
  • We Work Around What’s Already There: Driveways, garden beds, fencing, limited access, our crew is used to working in constrained sites without causing collateral damage.
  • No Handoffs, No Gaps: One team from assessment to completion. We don’t sub out portions of the job or leave you chasing separate contractors to finish what we started.

How It Works

  1. Start by telling us the basics: Give us information about the tank type, location on the property, and any access details. You can connect with us by a simple call.  
  2. We visit and have a proper look:  Once we have enough information about the tank, we will come out to the site and assess the area, and we will give you a reasonable quote based on reality.
  3. We complete the job cleanly: Right materials, properly compacted, site tidied. If you need documentation at the end, we have it ready. Nothing left unfinished.

Questions you may have

Is backfilling a legal requirement for decommissioned tanks?

For fuel tanks, generally yes. Most council and environmental regulations require underground tanks to be properly filled or removed once out of service. Leaving one in place, especially before a property sale, can create real liability.

Based on the tank type, depth, and what the surrounding ground can take. Flowable fill works well for larger tanks with awkward shapes. Gravel or compacted fill suits shallower or smaller structures. It's not a one-answer situation.

A standard residential tank is usually done within a day. Larger jobs or tricky access points take longer, we'll be upfront about timing before we schedule anything.

The tank is underneath my driveway. Will that be a problem?

We give you proof of the work done; handy for council records, property settlements or development applications. Let us know when you book and it’ll be arranged before we leave.
