South County Sand and Gravel provides armourstone for coastal and flood protection. We also can supply armourstone for offshore subsea engineering. Armourstone is natural quarry stone, chosen for its durability and resistance to wear and erosion.
Armourstone is the most important construction material for building breakwaters in our coastal waterways. They function to dissipate wave energy as waves hit the exterior of the breakwaters and move through the gaps between the stones.
