Application & Maintenance
Oyster shell, sun-bleached white in color, continues to break down over time making the ground cover more compact and level. One yard will cover approximately 100 square feet at 2-3" depth.
When used on driveways, walkways, courtyards and patios we recommend a gravel base layer before the shell is installed. On application, the crushed oyster shell requires compaction allowing it to re-calcify making a hard, porous surface.
During and after compaction lightly spray the area with water.
