All-in Concrete Gravel (20mm [¾"] all-in)

A blend of sand and gravel aggregate, also known as all-in ballast or mixed ballast. It requires only the addition of a cement (e.g. ordinary Portland Cement) and water to make concrete. It is also used for pipe bedding haunching and surrounding material (the exact all-in material used will depend on the nature of the pipe).

Complies with BSEN 12620. We regularly sample our gravels to check that grain size distribution meets specification.
