Rock Armour

Overview

Groundworx Grabhire Ltd. supplies high-quality Rock Armour, a robust and durable material used for coastal, river, and erosion control projects as well as commonly being used for security and decorative projects. Rock armour consists of large, angular stones specifically designed to protect structures and landscapes from the impact of water, waves, and weather.

This heavy-duty material is widely used in civil engineering, offering an effective solution for stabilizing shorelines, riverbanks, and embankments. Its strength, size, and angular shape make it highly effective at absorbing and deflecting energy from natural forces, ensuring long-term protection for critical structures. Rock armour is also used for decorative features as well as providing security to keep unwanted vehicles and people out land and car parks.

What is Rock Armour?

Rock armour is a natural or quarried stone aggregate, which varies in size depending on the use and requirement. Rock armour sizes start from 100mm to over 1000mm. These large stones can be carefully selected for their weight and angular shape depending on the requirement, which helps them lock together to form a stable barrier. Commonly used in riprap applications, rock armour is essential for safeguarding infrastructure and landscapes from erosion and damage caused by water or heavy loads.
