A Guide to AMS Terminology

When it comes to our products and services, you may see words on our website that you are not familiar with. In this article, we’re providing you with a dictionary of the AMS terminology to help you make your decision on your purchase. 

Aggregate grade 

You may have seen this when you’re browsing the bagged or loose aggregates on our website. Choosing your aggregate grade basically means the size of aggregate. For example, if you are looking to purchase our Washed Shingle product, you can choose from 10mm, 20mm or 40mm. It also covers the composition of the aggregate. 


An inert material is one that can be recycled, reused or repurposed (typically a waste material). It doesn’t change its form so can easily be recycled through screening, washing and crushing. Typical examples of an inert material are soil, rubble, stone so they can be processed into a recycled material. 

Muckaway/ Cartaway

You’ll find reference to Muckaway/Cartaway if you are on the ‘Tippers’ section of our website. Our Muckaway/Cartaway service is used at the initial stage of a construction project, it will remove the soil and vegetation that will come from the excavation of a site. 


Primary aggregates are naturally occurring aggregates which come from a quarry. 


This stands for Roll On Roll Off, think of it as a very large skip. A RoRo is perfectly suited to businesses, contractors or individuals who need to clear large volumes of light and bulky waste and is available in options from 15-40 yards. They can sometimes be called ‘Hookloaders’ and they are named due to the nature of how the skip container is loaded on and off the lorry. 


A secondary aggregate is one that has been repurposed from an alternative aggregate. 


A sub base is an aggregate or aggregate mix that forms a sound, load-bearing base layer for applications such as the construction of roads, paths and pavements. Aggregates you can use as a sub-base include: 

  • Scalpings
  • Type 1 recycled
  • Type 1 limestone
  • All in ballast (when mixed with cement)

Static waste containers  

Also known as compactor containers, we provide enclosed 35 cubic yard (26.8 cubic metre) RoRos (rollonoffs), which are ideal for securely containing large volumes of waste that are compressed by the user’s own static waste compactor.

Haulage and tonnage rate  

Some of our larger waste disposal options are charged using a haulage and tonnage rate as opposed to a ‘all in one’ cost. So if you have a large amount of waste to dispose of, this is a very cost effective way, as you will only be paying for what you dispose of.  


When looking for concrete, you would have seen that we offer volumetric or ready mixed concrete. 

Our volumetric concrete mixing trucks make the process of acquiring just the right volume of concrete for your construction project hassle free and cost-effective.

The volumetric lorry is a mobile concrete plant so it mixes the concrete on site.  

You can read more FAQs about volumetric concrete here.


This stands for Waste Electrical and Electronic Equipment and would be referenced in the skip section of our website. WEEE is a hazardous waste so cannot be disposed of in a standard mixed waste skip. 

4, 6, 8, 12 yard

These are the sizes that skips come in that can be hired from Avon Material Supplies. It’s important to choose your skip size wisely to ensure the most cost effective solution for your project.
