Marine Aggregates:
Sustainable Sand & Gravel from the Sea

Marine-won sand and gravel represent a significant and growing section of the UK's construction demands. Our high-quality marine aggregates sourced from our dredge areas off the south coast of England are responsibly managed, tightly regulated, and sourced from licensed areas of the seabed.

The location of our deposits, near major coastal population centres including Shoreham and Portsmouth, gives our Marine Aggregates team a logistic advantage. We deliver our materials by sea directly to local wharves, reducing long road transport routes, easing congestion, and cutting associated carbon emissions for your project.

Marine aggregates are a preferred choice for projects requiring exceptional quality and reliability. Our materials are recognised across various sectors for their consistent colour and grading. Add predictable volumes and yields and these attributes allow our aggregates to meet the high specifications of modern construction. This consistency is why our own Holcim ReadyMix division is a key internal customer.

Focusing on our planet’s sustainable future, we operate with a commitment to safety and environmental stewardship. Our UK-registered dredger, the MV AI Avocet, complies with all applicable international and UK marine regulations. We maintain a rigorous Safety Management System (SMS) under the International Management Code for the Safe Operation of Ships and for Pollution Prevention (ISM Code), which is fully certified by the UK Maritime and Coastguard Agency (MCA). Meeting or exceeding all requirements ensures that our operations are safe, efficient, and protects the welfare of our personnel and the marine environment.
