Why Heavy Waste Goes in Small Bins
Concrete and brick weigh roughly 1.2–1.5 tonnes per cubic metre, and wet soil can go heavier still. A skip truck can only legally lift a few tonnes, so the maths is unavoidable: a 6m³ bin of concrete would weigh eight-plus tonnes and simply couldn't leave your property. That's why every reputable operator restricts concrete, brick, tile and soil to 2m³, 3m³ and 4m³ bins — it's physics and Queensland transport law, not upselling.
The practical upside: heavy waste jobs rarely need big bins anyway. Demolished materials compact tightly, and an old single-car driveway — which looks like a mountain when it's jackhammered up — typically fits in 3–4m³.
What Counts as Heavy Waste
Clean concrete and brick: broken slabs, paths, driveways, footings, besser blocks, bricks and pavers. "Clean" means free of general rubbish, soil, green waste and large amounts of embedded timber. Small amounts of reinforcing mesh in concrete are normal and accepted.
Roof tiles: terracotta and concrete tiles from re-roofs. A full roof strip on an average home produces several tonnes — talk to us about quantities before booking one bin for the lot.
Soil, dirt and clay: excavation spoil, garden bed strip-outs, trenching spoil, lifted turf. One important distinction: clean fill (natural soil, clay, rock, free of contamination) is handled differently from soil mixed with rubbish or building debris — clean fill is far cheaper to dispose of, and Gladstone Regional Council's Benaraby facility has at times accepted clean fill at reduced or no charge. Keep it clean and say so when booking.
Mixed heavy loads: brick-plus-soil, concrete-plus-tile and similar combinations are usually fine in the same bin, but tell us the mix — it affects the disposal stream and price.
The Golden Rule: Don't Top It Up
The most expensive mistake in heavy waste hire is treating the last bit of bin space as a bonus general-waste run. A heavy bin "topped up" with fence palings, garden bags and an old barbecue becomes a contaminated load — it can't go to the concrete crusher or the clean fill area, gets reclassified to a dearer disposal stream, and may attract sorting fees. Clean concrete and brick, by contrast, gets crushed into road base and recycled aggregate, which is exactly why it's cheap to tip. Keep the load pure; run a separate general waste bin or construction bin for everything else.
Typical Gladstone Heavy Waste Jobs
- Driveway and path removal — the classic. A single-car concrete driveway is usually a 3–4m³ job; a front path or shed slab fits a 2m³.
- Paver and retaining wall tear-outs — common as older landscaping around Kin Kora, Clinton and Telina gets refreshed. Pavers stack tight; don't overestimate.
- Re-roofing — tile strips from Gladstone's older housing stock. Coordinate bin count with your roofer's schedule.
- Garden bed and turf strip-outs — soil bins for landscaping resets, often paired with a green waste bin for the vegetation.
- Pool surrounds and patio demolition — mixed concrete/paver loads, well suited to a 4m³.
- Excavation spoil — post-hole, trench and footing spoil from builds and fence jobs across the region's expanding edges in Kirkwood and Tannum Sands.
Loading Tips That Save Money
Break slabs into pieces one person can lift — smaller pieces pack tighter and load faster. Load evenly across the bin floor rather than in one mound, keep everything below the rim (level loads are a legal transport requirement), and hose the dust off nothing: dry loads weigh less than wet ones, and soil especially gains real weight after rain, so tarp an open soil bin if weather's coming.
