Man made or concrete paving is often referred to as reconstituted stone paving. It is formed using one of two methods: Wet-Cast or Pressed. When wet-cast, the concrete mix is poured into moulds and then vibrated to remove air bubbles. This type of paving is a higher end product with a fine finish and is often more ornamental with a slightly tapered or rounded edge. Pressed paving slabs are made with a semi-dry concrete mix and hydraulically pressed to create a functional yet slightly porous slab. They tend to be used for utility purposes such as shed bases, and where aesthetics are not of prime importance.
Concrete paving has dye within the concrete mix to colour the paving. The premium paving products tend to stay true to colour for longer than cheaper concrete paving, however all concrete will fade over time, especially if cleaned regularly using chemical cleaners.
