GRAY VOLCANIC POZZOLAN



Natural gray-black volcanic rock.



Porous structure and low density.  


Applications

For the fabrication of substrates because it provides a good structure, water retention and capacity for retention.

For drainage in planters.


For decoration in gardens:

Prevents the spreading of weeds.
Saves on the consumption of water.
Protects plants from frost and drought.

Spread a uniform layer of 5-7 cm of the volcanic pozzolan. 
If you want to completely eliminate the growth of weeds, it is recommended to put an anti-germination mesh before spreading the volcanic pozzolan.
