La Marmolina Blanca are volcanic rocks (or pozzolans) of great decorative value designed to beautify pots, planters and flower beds.
It can be used as a drainage element in the base of pots and planters for the evacuation of excess irrigation water.
Raw siliceous stone, residual of ancient volcanic eruptions, is particularly light and decorative. It prevents weeds growth, keeps the ground humid in summertime and in winter gives plants a good protection against cold weather.
Volcanic stone, selected and cut into blocks , is a valid alternative in any type of building: fences, floors, flower stands etc.
