How bin weighing works
After we collect your bin, it goes to a licensed SA EPA-approved weighing facility. The bin is weighed full, then weighed empty — the difference is your waste weight. If it exceeds the included allowance for that bin size, you are charged $340/tonne (or part thereof) for the excess, directly to the credit card on your account. You receive an email with the weighbridge details and your receipt.
The weigh certificate is your only record of the charge. If you believe the weight is wrong, you can contest it through the facility — they record every scale reading.
Included disposal weight by bin size
Every bin can hold up to 10 tonnes maximum. The included weight varies by size. A 12m³ Medium at $1,150 includes 2 tonnes of disposal — anything over 2t costs $340/tonne extra.
| Bin size | Price from | Included weight | Max weight |
|---|---|---|---|
| 9m³ Standard | $850 | 1.5t | 10t |
| 12m³ Medium | $1,150 | 2t | 10t |
| 15m³ Large | $1,450 | 2.5t | 10t |
| 20m³ XL | $1,750 | 3t | 10t |
| 30m³ Maxi | $2,100 | 3.5t | 10t |
| 40m³ Super | $2,750 | 4.5t | 10t |
Material weight reference
- Concrete & brick: ~2.4 tonnes per m³ (very heavy — 1m³ of concrete alone is nearly 2.5t)
- Soil, clay, wet earth: 1.4–1.8 tonnes per m³ (depends on moisture)
- Timber & demolition wood: ~0.5–0.8 tonnes per m³ (light)
- Mixed renovation waste (plaster, timber, rubble): ~1.0–1.3 tonnes per m³ (light to medium)
- Furniture & household: ~0.4–0.6 tonnes per m³ (light)
- Green waste & garden: ~0.3–0.5 tonnes per m³ (very light)
Concrete is the weight killer. 1 cubic metre of concrete = 2.4 tonnes. A 15m³ bin with 2.5t included can only hold about 1m³ of concrete before overweight charges kick in.
Practical load-planning tips
- Estimate volume first: 1m³ roughly equals one 6×4 trailer load.
- If your load is mostly concrete or soil, calculate volume × material density (use 2.4t/m³ for concrete).
- Compare your estimate to the included weight. If it's close or over, book the next size up.
- Separate heavy materials into a dedicated bin if possible — a bin of just concrete is cheaper to handle than a mixed load.
- Email us a photo and description of your load when you quote — we can estimate weight and flag likely overweight before you book.
- If you're near the limit, book a second bin. A second 15m³ at $1,450 is cheaper than paying $1,020 in overweight charges (3 tonnes over at $340/t).
When to book a second bin instead
If your load is heavy and close to the limit, a second bin often costs less than paying overweight. Two 15m³ bins total $2,900 and include 5 tonnes of disposal. A single 15m³ with a 5-tonne load costs $1,450 + $1,190 in overweight = $2,640 — but that assumes perfect estimation and no surprises. Book a second bin if you want certainty.
For demolition work with a lot of concrete, always consider splitting the load across two bins or choosing a larger single bin up front.
