Exposed
aggregate remains each extremely popular as it combines the
strengths of concrete, ease of mould manufacturing with the
decorative appeal of the aggregate and relatively low cost production.
The Moulds in this category have a plain surface and are ideally
suited to exposed aggregate casting. Simply pour the aggregate
into the base of the mould, pour the concrete into the mould
to fill, then once demoulded, wash away 1 - 2cm of concrete
to expose the aggregate.
