How much stone do I need?

How much stone do I need for the ground?

For shot and gravel song:
• ± 80kg per m², based on a 5cm layer.*For granulometries> 32mm a thicker layer is necessary.• Saca consumption: 1000kg = 0.625m³.
• Covering capacity: ± 12.5m² with a layer of 5 cm.

For pine cortex:
• ± 70L per m², based on a 5cm layer.
• Saca consumption: 1000L = ± 1m³ = ± 600kg
• Covering capacity: ± 14m² with a layer of 5 cm.

For volcanic, slate and chamota:
• ± 50kg per m², based on a 5cm layer.
• Saca consumption: 1000kg = ± 1m³
• Covering capacity: ± 20m² with a layer of 5 cm

How much stone do I need to fill a gabion?

Density of ± 1,650kg by 1m³.

The calculation is very simple to understand with an example, if you have a 100x50x30 cm gav. You have to make the following accounts:
1x0.5x0,3 = 0.15m³
0.15x1,650 = 247.50kg. stone.
*It is always good to calculate an extra 5%, since the gavions when filling them are a little and always enters some more stone than in the theoretical calculations.

Clarifications

ATTENTION!

Granulometries are sizes of sizes

Real sizes can vary slightly, since when talking, for example, 60-80mm stone, it means that the stones pass through a square mesh of 80x80mm. and do not go through a 60x60mm.
This 80x80 mesh can pass a 100mm stone. long and 65mm. wide so there may be a percentage of stones greater than 80 and less than 60mm.

Broken stones

On the other hand, in the stones of more than 60mm. There is a percentage of up to 10% stones that can be broken during classification, washing, loading and downloading, today we have no machinery that avoids those breaks.

In the photos you can see, only real products are seen, broken pieces have been removed.

Dust and sand in 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 be washed alone over time or can throw water before using it.
