How much stone do I need?
How much stone do I need for the ground?
For pebble and gravel:
• approximately 80kg per m², based on a 5cm layer.*For particle sizes >32mm, a thicker layer is required.
• Consumption per sack: 1000kg = 0.625m³.
• Coverage: approximately 12.5m² with a 5 cm layer.
For pine bark:
• approximately 70L per m², based on a 5cm layer.
• Consumption per sack: 1000L = approximately 1m³ = approximately 600kg
• Coverage: approximately 14m² with a 5 cm layer.
For volcanic, slate and chamotte:
• approximately 50kg per m², based on a 5cm layer.
• Consumption per sack: 1000kg = approximately 1m³
• Coverage: approximately 20m² with a 5 cm layer
How much stone do I need to fill a gabion?
Density of approximately 1,650kg per 1m³.
The calculation is very easy to understand with an example: if you have a gabion of 100x50x30 cm, you must do the following calculations:
1x0.5x0.3 = 0.15m³
0.15x1,650 = 247.50kg of stone.
*It is always a good idea to calculate an extra 5%, since when gabions are filled they expand a little and a little more stone always fits than in the theoretical calculations.
Clarifications
ATTENTION!
The grain sizes of GRAVELS AND pebbles are sieve sizes
The actual sizes may vary slightly, since when talking about, for example, 60-80mm stone, it means that the stones pass through an 80x80mm square mesh and do not pass through a 60x60mm one.
Through that 80x80 mesh, a stone 100mm long and 65mm wide can pass, so there may be a percentage of stones larger than 80 and smaller than 60mm.
Breakage of pebbles
On the other hand, in pebbles larger than 60mm, there is a percentage of up to 10% of stones that can break during sorting, washing, loading and unloading; to this day we do not have machinery that prevents such breakages.
In the photos you can see, only real products are shown; broken pieces have not been removed.
Dust and sand in the products
This product is not washed, so it contains dust, sand and even traces of other products due to processing and transport. This is not a problem when using it; the stone will wash itself over time or you can pour water on it before using it.
Expanded Vermiculite
Expanded Vermiculite is a natural mineral that belongs to the mica group, primarily composed of iron and magnesium silicates. Its extraction takes place in open-pit mines, where it is processed to remove rocks and impurities, obtaining a mineral classified by size.
Subsequently, the Expanded Vermiculite undergoes a thermal treatment known as exfoliation, which allows the mineral to expand up to 12 times its original volume. This process highlights key characteristics that make this material an ideal option for multiple applications.
Properties of Expanded Vermiculite
- Light and clean: Perfect for use in sensitive environments.
- Thermal and acoustic insulation: Provides excellent insulation properties.
- Non-combustible and insoluble in water: Resistant to high temperatures and humid conditions.
- Absorption capacity: Ideal for applications that require managing liquids.
Uses of Expanded Vermiculite
Industry
Used in the creation of mortars and refractory elements, as well as passive fire protection. In metallurgy and foundry, it acts as a cushioning for liquid metals.
Agriculture
It is ideal for tray covers in seedbeds, maintaining temperature and humidity. Additionally, when mixed with organic substrates, it improves aeration. In animal nutrition, it facilitates nutrient loading in feed additives.
Construction
Functions as a basic ingredient in the production of lightweight projection plasters and in the creation of vermiculite boards or panels, providing fire resistance and thermal stability.
The versatility of Expanded Vermiculite makes it an essential product for various industries.
