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.
Black Slate Gravel
Black Slate Gravel: The Reference Aggregate for Cutting-Edge Landscaping
The Black Slate Gravel is a French-imported aggregate specifically selected for projects that require a decorative pavement with its own identity. Unlike conventional basalt or granite blacks, this stone stands out for its controlled mineral heterogeneity, providing a rich and natural visual texture that avoids the "flat" effect in large expanses.
It is the preferred choice of architects and landscapers seeking a balance between the sobriety of black and the warmth of natural stone.
Main Features
-
Exclusive Origin: Selected directly from French quarries under strict granulometry controls.
-
Multitonal Aesthetic: Its dark base intertwines with mineral inclusions in white and gray tones, creating a subtle contrast that adds depth to the surface.
-
Professional Resistance: Stone with high mechanical hardness. It withstands wear from traffic and maintains its unaltered color intensity against UV radiation and weather conditions.
-
Minimal Maintenance: Its nature prevents excessive compaction, facilitating drainage and cleaning.
Recommended Applications
The Black Slate Gravel is extremely versatile, particularly excelling in:
-
High-Level Xeriscaping: Ideal for sustainable gardens seeking a premium visual impact.
-
Transition Areas: Perfect for hotels, residential complexes, and corporate spaces.
-
Design Contrasts: Combines masterfully with elements of technical wood, exposed concrete, and especially with the oxidized character of corten steel.
Technical Specifications
-
Color: Black with white and gray mineral hues.
-
Texture: Slabbed / Angular (excellent for stability in pavements).
-
Format: [Add available granulometries here, e.g., 6-12mm / 12-22mm].
-
Presentation: Available in bags, Big Bags of 1000 kg, and bulk.
Vetonek Advice: For a flawless finish and to prevent weed growth, we recommend the prior installation of our professional weed control fabric and the use of aggregate fixation resin in passage areas.
