Description

Crushed coquina is a granular material made by breaking up Coquina, a soft sedimentary rock composed mostly of broken shell fragments from marine organisms.

Description

• Composition: Primarily crushed shells (such as clams and other mollusks) that have naturally cemented together over time with calcium carbonate.

• Color: Usually light tan, cream, or off-white, sometimes with pinkish shell pieces mixed in.

• Texture: Rough, porous, and gritty, with irregular shell fragments visible.

• Particle size: Ranges from fine sand-like grains to small gravel pieces, depending on how finely it’s crushed.

• Drainage: Highly permeable, allowing water to pass through easily.

• Hardness: Relatively soft compared to limestone, so it compacts but can break down gradually under heavy traffic.

Common Uses

• Driveways and rural roads

• Walking paths and landscaping

• Base material for patios or pavers

• Decorative ground cover

• Historic restoration, especially in coastal regions where coquina is native
