Frequently Asked Questions

Here you can find answers to the most questions that we are asked by our customers. But if you can’t find the answer you’re looking for, please give us a call.

Bin Types and Sizes

The Bins page provides information on the size of each bin to help with this decision. In our experience, the majority of customers need a 4m3 mobile skip bin, while a small number need the bigger bin.

Sometimes it can be hard to visualise how big 4m3 is, so we've put together a simple explanation of how to figure this out.

This all depends on the type of rubbish you want to remove:

  • General Waste is typically anything involved with a “general cleanup around the house” and that is neither liquid nor of a hazardous nature.
  • Green Waste includes grass, leaves, tree trimmings, small branches and other organic materials.
  • Heavy Waste includes concrete, dirt, sand, clay, rocks, rubble, and bricks. This type of waste is only allowed in Trailer Trash mobile skip bins in very small quantities.

Visit the Waste page for more information

Our trailers are around 2.3m wide, and around 3-3.5m long. Depending on the size of the bin, they can be as low as 1.95m high, or up to 2.4m high. Full information on the dimensions can be found on the Bins page.

If you can get a car up your drive, then we can almost always get one of our mobile skip bins into the space. We need a space that is 2.4m wide to get into and occasionally gates are too narrow for us to enter, or in some inner city suburbs some driveways are narrow, particularly in houses built before 1940. If you have a narrow space it is worth measuring.

Remember that Trailer Trash mobile skip bins are road-registered trailers and therefore they can be parked in the street without needing a council permit, as long as parking restrictions are followed.

Waste and Weight

This is one of the most difficult questions to answer when trying to work out which bin to order, and whether to upgrade the weight limit. Here's a simple guide to the weight of items that commonly go into our bins, and remember that heavy waste should only go into 4m3 bins, not our larger 6m3 bins.

  • Books and Paperwork: Books are surprisingly heavy when you pile them up. As a rough rule of thumb, estimate about 1 tonne per cubic metre of books and/or paperwork.
  • Bricks: In our experience, bricks from a demolition weigh around 4kg each because of the mortar that is stuck to them. This means that 250 bricks will weigh around 1 tonne.
  • Carpet: This depends on the type of carpet, and whether you have underlay. As a rough rule of thumb, we suggest estimating around 5kg per m2, but this needs to increase for heavy duty carpet or thicker pile.
  • Carpet Tiles: Like carpet, carpet tiles vary in weight depending on the quality and thickness. However, as a rough rule of thumb, we suggest estimating around 5kg per m2 but remember that the tiles tend to pack more densely than carpet. We once had a bin that was only half full of carpet tiles, but it weighed over 2 tonnes and had to be emptied by hand.
  • Concrete, Tiles and Rubble: This is generally the heaviest type of waste we deal with, and can quickly tip you over the weight limit. A cubic metre of this type of waste is usually somewhere between 2 and 2.5 tonnes, so if you have this kind of waste you need to limit it to half a cubic metre or less.
  • Decking: The weight depends on the type of timber, thickness of the timber and how big the gaps are. For a common deck made of 90mm wide, 19mm thick merbau, the decking itself will weigh around 15kg per m2. Pine will generally weigh a little (but not a lot) less. If you also need to estimate the weight of the supporting structure (joists, etc), this also depends on the design, material, etc. As a really rough rule of thumb, joists will generally add around 10-15kg per m2 of decking, but the weight of posts will vary wildly depending on the deck.
  • Dirt and Sand: Dry dirt and sand generally weighs around 1 tonne per cubic metre, or just a little bit more. However, if it is damp, it can quickly jump to 1.5 - 2 tonnes per cubic metre.
  • Rocks: Rocks can weigh anywhere between 1.5 tonnes and 2.5 tonnes per cubic metre. In general, the smaller the rocks, the higher the weight, as there is less air in between the rocks.

As always, this depends on the size of the wheelbarrow and the type of waste. A common size of a wheelbarrow is 100L, which is 1 tenth of a cubic metre, if level loaded (i.e. it doesn't go above the sides). So, for example, if you are filling your wheelbarrow with concrete, each wheelbarrow load is going to weigh around 200-250kg. This is why we recommend 1-2 wheelbarrows of heavy waste in a kg bin, and 4-5 wheelbarrows in a kg bin.

Take a look at the How heavy is my waste? question, and then use the size of your wheelbarrow to get a rough idea of the weight of each load.

Different bins have different weight allowances, which you can see on the Bins page. If your skip exceeds your weight allowance, you will be charged an additional fee of $ per 100kg. Some waste is very heavy and could lead to large excess fees so please contact us if you are unsure about your needs.

Skip bins should not be filled any higher than the top of its sides. We must be able to fully close the lids to prevent spillage of material from the skip bin while stationary and in transit. Spilled contents can be extremely dangerous on roads, and it’s bad for the environment.

You cannot put any hazardous waste into the skip bins, so you will need to contact your local council to dispose of this. For more information, check out the Waste page.

No, sorry, we can't take your mattress. However, if you need to get rid of a mattress check out our blog post on the topic, which should get you sorted.

Yes, we can. However, these need to fit easily into the bins without getting jammed. Therefore we need you to cut or break them up into pieces before putting them in.

We can take large appliances, and we send them to recycling to avoid landfill and reduce your weight, but there are a few conditions:

  1. You need to let us know in advance so we are prepared to handle them. You can either put some comments in when you order online, or let us know when you order over the phone.
  2. The appliances need to be placed on top of all the other waste so we can remove them easily.
  3. We still need to be able to close the lids on the bin for safe transportation.
  4. The appliances must be small enough to get out of the bin easily. Generally bar fridges are ok, but many larger fridges are too large to easily remove.

If in doubt, give us a call and we'll be able to answer any questions you have.

We are charged for the disposal of our waste based on a combination of volume and weight. This means that if you go over the allocated weight, we get charged more by our supplier. We don't know the actual weight until the bin is emptied, and that's why the excess weight charge is processed after your bin is collected. If your bin weighs too much, all we do is pass that cost onto you, so that you're not being stung unfairly while not putting us out of pocket either.
