Turn to Winters for aggregates in London, Hitchin or the Home Counties
Although Winters has a strong reputation for waste management services like skip hire and grab lorry hire, it also has many customers for its aggregates.
Aggregates are the mineral materials that are used in the creation of concrete. Our extensive selection of aggregates shows that we are not just the go-to company for waste management services, but can also provide various other products and expertise to the construction industry.
We sell aggregates loose by the metre or by tonnage on bulk loads that exceed 10 tonnes (10,000kg). Our full selection of aggregates in stock includes soft sand, sharp sand, ballast 20mm, MOT type 1 + certificate and hardcore.
We produce the following recycled materials
Washed Recycled Products
40mm Washed Recycled Stone
For use as a drainage stone
Dry Recycled Products

This is a 50mm down sub-base material, ideal for use on road and track improvements
This material is used as a trench fill
25mm Crushed Asphalt
This is used for surfacing, on pathways, tracks and roads
Calculating coarse aggregate and fine aggregate
The amount of coarse aggregate that you will need is equal to the volume that will be concreted. Calculating the ballast therefore depends on knowledge of the volume that is to be concreted. To work out the required tonnage, you should multiply the volume of concrete by one fifth. The volume in cubic metres can be calculated, with concrete of five cubic requiring seven and a half cubic metres. How the concrete is used and the size of the ballast to be used also makes a difference.
Meanwhile, you will need to be familiar with the properties of fine aggregate to calculate its amount. When sand is wet, it bulks, whereas when it is dry, it shrinks. The volume that you will need to concrete is the same as 80% of the volume of sand that you will generally require, so you will therefore need to take into account bulking or shrinkage by adding about 20% more sand. Aggregates can be measured with appropriate batching boxes.
