How does concrete’s durability compare to natural stone in coastal erosion zones?

When evaluating construction materials for coastal erosion zones, concrete and natural stone are often compared for their durability. Concrete, a man-made material, is engineered for strength and can be reinforced with additives to resist saltwater corrosion and wave impact. Its homogeneous composition allows for consistent performance, though long-term exposure may lead to cracking or spalling.

Natural stone, such as granite or basalt, offers inherent resistance to erosion due to its dense mineral structure. It withstands abrasion well and often requires less maintenance than concrete. However, its performance varies based on geological composition, and certain types may degrade faster in aggressive marine environments.

In coastal erosion zones, concrete is often preferred for large-scale projects due to its customizable properties and cost-effectiveness, while natural stone excels in aesthetic applications where longevity and minimal upkeep are priorities. The choice depends on environmental conditions, budget, and project requirements.
