What are marine aggregates?


Marine aggregates are naturally occurring sand and gravels found on the inner continental shelf off the UK coast.

The geological origin and mineral composition are the same as land based sands and gravels and they therefore exhibit the same geological mechanical, geometrical and chemical properties as their land based equivalents.

The shape, strength and other physical characteristics are generally identical to high quality land-based aggregates.
