Aggregate sources described as being from a secondary source indicate the materials are not being used for the first time. This may indicate the material is from a recycled source or that the proposed use is not that which was originally intended. Examples include:
In line with current recommendations from the latest British Standards, each source would need to be tested on a regular and routine basis for a variety of performance criteria, including physical, chemical and mechanical properties. ENVERiTY is able to provide a comprehensive testing service on secondary sourced aggregates including sampling, insitu and laboratory testing.
