Composition
Volcanic substrate consisting of a mixture of volcanic materials (pumices and lapilli), blond peat and/or organic substances with humus (like composted vegetable material) and complex fertilizers with Nitrogen in the form of controlled transfer.
In function of the kind of greening application (extensive or intensive) and the carrying capacity of the covering, it is possible to choose between:
FUNCTIONAL PROPERTIES:
– VULCAFLOR is a finished product, soft textured, free form toxic or dangerous substances and weed seeds.
– VULCAFLOR is a ideal substrate for the construction of green roofs, flower boxes and every type of realization in the green where a reduced intervention of maintenance is required.
– VULCAFLOR intensive forms a fertile root layer for the essences of green gardening.
– VULCAFLOR extensive is a ideal substrate for the construction of green roofs of the extensive type with reduced thickness, available load bearing capacity of the attic (100-200 kg/mq) and lawn with plant essences with reduced water and nutritional needs.
– VULCAFLOR LIGHT is a light substrate ideal for the pump in the construction of green roofs.
