armourstone

The Peak of Sea Defence Against Coastal Erosion

Armourstone or rock armour plays a critical role in coast protection by serving as a natural and highly effective defence against coastal erosion, storm surges, and wave impacts.
Armourstone is a coarse rock available from a size range within the BS EN 13383 specification. It's an effective choice for the protection of shorelines, structures and rivers offering long lasting wave dissipation and scour protection.

Our rock armour is a form of hydraulic engineering used to disperse wave energy and reduce the impact of waves crashing against any shoreline infrastructure. It also boasts excellent drainage properties in order to maintain the structure of the land.

Protection from erosion

One of the primary functions of armourstone is to prevent coastal erosion, which occurs due to the constant action of waves and tides. By creating a physical barrier, armourstone shields the shoreline from being worn away, preserving beaches, cliffs, and coastal properties.

Durability and Strength

Our rock armour is designed to withstand the test of time due to its hard wearing properties. It is a high quality rock, with a strong resistance against erosion. Its durability ensures that it remains effective for many years, reducing the need for ongoing repairs.

Weight and Dimension

All size ranges can be supplied in order to meet your requirements. The rocks can easily interlock to dissipate energy from the waves. Its flexibility allows it to be added or reshaped over time to meet evolving coastal protection needs.

ARMOURSTONE IN ACTION

Why Armoustone?

Our highly durable Armourstone should be your first port of call for anything sea defence related, and we can provide you with a solution for our high quality product all over the country. Armourstone is designed to absorb and dissipate the energy from incoming waves, reducing their impact on the coastline. By breaking up waves and reducing their force, it minimises the risk of erosion and damage to coastal structures. The permeability of Armourstone slows the water flow, reducing the effect of erosion.

The size and weight of Armourstone, combined with its irregular shape, allow the rocks to interlock naturally, forming a stable and cohesive structure. This interlocking nature ensures that the rocks remain in place, even in the face of strong wave action

We have numerous sites all over the country that can create products of this size to meet all grading & specification requirements. We have plenty of sites who can provide a highly durable product for all of your sea defence needs.

We can transport our heavy duty Armourstone across the country with excellent logistics services meaning we can distribute by sea, road or rail. This also works towards our sustainability goals as we can differentiate our modes of transport depending on your requirements.
