FUNCTIONAL CHARACTERISTICS AND FIELDS OF USE

Natural inert, ideal for:

? build substrates for plants that require the presence of carbonate in the substrate;

? with gypsum (1 part of gypsum and 3 parts of marble) if you want to create an acid reaction in the substrate with the release of magnesium ions;

? decorative if placed above the root system of potted plants or on the ground;

? mulch flower beds or areas of the garden where you want to avoid the growth of grasses or weeds.

NB: SHIPPING NEWS

THE BIG BAG FOR SALE WEIGHS ABOUT 1.500 KG, SO IT CANNOT BE UNLOADED BY THE COURIER IN CHARGE OF THE DELIVERY WITH THE HYDRAULIC TAILORING OF THE TRUCK (THE HYDRAULIC SIDES OF THE TRUCKS CAN UNLOAD UP TO A MAXIMUM OF 1.200 KG). IT WILL THEREFORE BE THE BUYER'S RESPONSIBILITY TO UNLOAD THE BIG BAG USING ITS OWN COMPATIBLE AND CERTIFIED MEANS IN ACCORDANCE WITH THE LAW FOR SUCH OPERATIONS.

NB: AVAILABILITY OF THE MATERIAL

The material is subject to availability, it is usually taken directly from the manufacturer in the quarry and sent to the customer in order to always have a clean product in excellent condition. We therefore ask our customers to check availability and delivery times by contacting Geosism & Nature sas

NB: PACKAGING NEWS

It should be noted that the aggregate is packaged by the manufacturer in big bags that can vary in shape, type and color depending on the availability on the market (therefore the photograph of the big bag is entirely indicative: it is only the container of the material ). The aforementioned big bags contain material that has a variable weight depending on the humidity contained (due to the climatic conditions during extraction inside the quarry) and depending on the specific weight of the material itself (which varies according to the extraction point at the 'interior of the quarry: the material, being of natural origin, has chemical-physical characteristics that may vary slightly during the geological period of formation). For this reason, there may be small variations in weight (both for defect and for excess) due to the reasons listed; Geosism & Nature sas is not responsible for such variations which are exclusively attributable to the manufacturer.

NB: GUARANTEES

Geosism & Nature sas certifies that the rock sold in this listing is totally natural and has not undergone any type of chemical treatment that could in any way pollute the soil or the crops with which it comes into contact. For the same reasons, Geosism & Nature sas is not responsible for any changes in the color of the stone due to the climatic conditions of the place (rain, humidity, snow and / or frost) or to any fertilization or irrigation done with particularly aggressive water or which they have elements in solution that can, in some way, alter the chemism - and therefore the color - of the rock itself (eg carbonates in general, salts, iron, manganese, molybdenum, heavy metals in general, etc ...). Remember that all stones that do not undergo chemical treatments can absorb water and with it the previously mentioned elements.
