Commercial Rock Armour Projects

on Thursday, 22 January 2015. Posted in News

We have completed numerous commercial projects throughout Ireland which include the supply of rock armour to complete works. Rock armour is most commonly used as a sea defence mechanism to support piers and to protect land from sea erosion.

Recent Rock Armour Projects

We recently completed rock armour works on Arranmore Island and Creevey Pier in Ballyshannon. Equipment and materials required for the Aranmore Island project were transported by ferry. We have also completed rock armour sea defence projects on Tory Island, Maghery and Mahergroarty. Our stone is excelllent for sea defence walls as it does not erode with the impact of sea salt water.

What Do These Projects Involve?

In order to complete these projects, Donegal Granite transport and place large boulders in amounts of up to 10 tonnes or above and stack them along the shoreline which forms a sea defence wall. The rocks are piled on top of each other, with gaps left between to allow the water to escape. This process reduces the impact of the waves and results in less erosion. It is important that we place large boulders which are highly resistance to sea water erosion such as Granite and Basalt stone. Small rocks would not be able to withstand the impact of the waves and would therefore result in the occurance of erosion.
