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.
Topdressing for grass
- What is topdressing for grass?
Topdressing for grass is an organic material, a mixture of decomposed organic substrate, silica sand, and mulch that is applied to grass to improve its growth, ensure that the soil is moist and nourished, and also to increase its resistance to drought and insects. The mulch is a plant-based product, usually made from branches and leaves of trees.
- Why is topdressing for grass used?
Topdressing for grass is used to improve soil structure, provide nutrients and moisture to the grass, prevent soil compaction, and increase resistance to drought and insects. This helps maintain a healthy and vigorous lawn. Topdressing is also used to prevent the loss of nutrients and moisture due to evaporation and to provide an optimal amount of organic matter to the soil.
- How is topdressing for grass used?
Topdressing for grass is applied to the grass to improve its growth and resistance to drought and insects. A layer of approximately 2-3 cm deep of topdressing should be applied to the grass, so that nutrients and moisture are distributed evenly. After applying the topdressing, it should be lightly raked to distribute it evenly.
- The advantages of using topdressing for grass
The use of topdressing for grass has many advantages, including improving soil structure, providing nutrients and moisture to the grass, preventing soil compaction, resistance to heat and drought, and an optimal amount of organic matter to the soil.
- How much should I apply per m² of grass?
The amount of topdressing that should be used per square meter of grass can vary depending on several factors, such as the quality of the existing soil, the type of grass to be sown, the climate, and local conditions. In general, it is recommended to apply a layer of topdressing of around 3-5 cm thick over the existing soil before sowing the grass. This is equivalent to about 30-50 liters of topdressing per square meter. It is important to remember that excess topdressing can be harmful to the grass, as it can obstruct the absorption of water and nutrients, and create an environment conducive to the growth of fungi and other diseases. Therefore, it is recommended to apply 30 L/m² or even slightly less.
