COMPOSITION: ALVEOLAR EFFUSIVE ROCK WITH OPEN CELLS
The material is essentially an effusive magmatic mineral (originating from the Vulsini volcano during the Pleistocene period) calcined at high temperatures. It is porous, lightweight, and insulating. This is a finished product with a fine texture, free of toxic substances or weed seeds.
IDEAL FOR:
- Growth substrate for root systems
- Drainage substrate for sports fields (football, tennis, etc.)
- Stabilizing drainage substrate for clayey soils
- Mulching
- Preparation of soil mixes
- Cultivation of potted plants, orchids, succulents, cacti, carnivorous plants, bonsai
- Thermal and acoustic insulation
- Soil amendment
- Substrate for aquariums
PHYSICO-CHEMICAL PROPERTIES:
- Water retention: 8-13% by volume
- Water availability: 6-9% by volume
- pH: 7-8
- CEC (Cation Exchange Capacity): approx. 18 milliequivalents/100 g
- No active lime
- NON-TOXIC product (free from silicate dust)
FUNCTIONAL PROPERTIES:
This material is especially recommended for drainage systems, making it ideal for lawns, sports landscaping, and construction technologies:
- Example: DIN standards in all variations
- STRI standards
- USGA drainage applications
- Uses in reinforced drainage systems
- Vertical drainage applications
