Skip names in South Africa are trade convention, not a national standard. There is no regulation that says a builders skip must be a particular volume, so two operators in the same suburb can sell you a bin of the same name at different sizes. Treat the ranges below as the shape of the market, then confirm the actual dimensions and the weight allowance with the operator quoting you.
The four domestic sizes, plus one
| Size | Usual volume | What it realistically takes |
|---|---|---|
| Mini skip | about 2–3 m³ | One bathroom strip-out, a small garden clear, or clean rubble from a modest demolition. The default for tight townhouse access. |
| Midi skip | about 4–6 m³ | A garage or spare room, a kitchen strip-out, a decent garden clearing. The most commonly hired domestic bin. |
| Builders skip | about 6–9 m³ | Site rubble on a live build, multi-room renovation debris, bulky household or garden loads. |
| Maxi skip | about 10–12 m³ | Whole-house clearances, shopfitting and office strip-outs, light but bulky construction waste. |
| Roll-on / roll-off | about 15 m³ and up | Sustained construction programmes and industrial yards, swapped on a cycle rather than hired once. |
Why the weight allowance matters more than the volume
The single most expensive mistake in skip hire is choosing on volume when the load is dense. Operators include a weight allowance in the hire price and charge for anything above it, because the landfill or crushing plant charges them by mass at the weighbridge. Rubble reaches that allowance at a fraction of the bin's capacity.
These indicative bulk densities explain the gap. They are order-of-magnitude figures for reasoning about a load, not a substitute for the tonnage in your quote:
| Material | Indicative bulk density |
|---|---|
| Broken brick, block and concrete | ≈ 1.3–1.6 t per m³ |
| Sand, soil and excavation spoil | ≈ 1.4–1.8 t per m³ |
| Mixed renovation and strip-out waste | ≈ 0.3–0.6 t per m³ |
| Fresh garden refuse and cuttings | ≈ 0.15–0.3 t per m³ |
| General household and furniture waste | ≈ 0.1–0.2 t per m³ |
Run the arithmetic on a midi skip. Filled with household clutter it might carry half a tonne. Filled with broken concrete it would carry six or seven tonnes, which no domestic skip lorry is going to lift. That is why an operator will tell you to put rubble in a mini and why a maxi skip is the wrong answer for a demolition, however much rubble you have.
Sizing without guessing at cubic metres
Almost nobody can estimate volume accurately by eye. Describe the job instead and let the operator size it — they do this daily.
- For clearances, count rooms and garages rather than cubic metres.
- For demolition, give the square metres of floor or wall coming out and the thickness.
- For gardens, describe the area cleared and the biggest branch you have.
- For renovations, split the job into the heavy part (tile, screed, plaster, brick) and the bulky part (timber, board, cupboards, packaging), and give both.
- If you think in bakkie loads, say so — one level single-cab load is roughly a cubic metre, which is a fine unit for this conversation.
Two smaller loads often beat one big one
On rubble and on staged renovations, two loads is frequently the cheaper answer. A single bin sized for the heavy phase will not hold the bulky fit-out phase, and a bin sized for the bulky phase will be over its weight allowance before it looks full. Ask what a swap costs so you can compare a two-load plan against a one-bin plan properly.
Questions that decide the size
- What weight is included, in tonnes, and what does each tonne over cost?
- What are the bin's actual internal dimensions, especially length for roof timbers and long boards?
- Does this bin take mixed waste, or does it have to be clean rubble only?
- How many days does the hire cover, and what does an extra day cost?
- Are delivery and collection in the price, or added?
- Which licensed facility does the load go to, and can I have the disposal slip?
