More questions about Rock Armour.
Can the public safely access rock armour?
Rock armour isn’t a walkway. The big, uneven stones can be slippery and hazardous, especially when wet.
Do you offer design support or just supply stone?
We don’t replace your engineer, but we do more than just drop rock at the gate. We work with your team on sizing, build-ups and constructability so your defence works on paper and on site.
How does rock armour compare to sea walls, gabions or sheet piling?
Rock armour gives you a solid, natural-looking barrier that helps take the force out of the waves before they hit the shore. In many exposed spots, it can work out cheaper to install and simpler to look after than a rigid concrete wall, gabions or sheet piles.
How long does rock armour last?
When correctly specified (appropriate rock type and size) and installed on a suitable foundation, rock armour can provide protection for several decades, often lasting 50-100 years.
Its lifespan depends on the durability of the stone (for example, hard igneous rocks like granite and basalt), local wave climate, water levels and how well it is inspected and maintained over time.
