How much gravel comes on a pebble bed? - How to calculate the quantity requirement
If gardeners clearly envision the construction of a pebble bed, the question of the material requirements in the room stands. Significant cost position in the budget is the required amount of gravel. Anyone who skits at this point will be annoyed by a patchy gravel blanket. Too generous calculation, on the other hand, drives up costs unnecessarily. This guide explains how to correctly determine the need for gravel.
Grain size defines layer height for opaque gravel surface
Flat heights for the layer height in the pebble bed are only a first orientation in the determination of needs. If you aim for an opaque gravel surface, the focus is on the grain size of your favorite type of gravel. Act here according to the following premise:
If you have chosen white quartz gravel in a grain size of 16-25 mm, apply the gravel at a height of 50 mm, that is 0.050 m. If you use donoauskies with a grain size of 8-16 mm, the dumping height is 32 mm, ie 0.032 m.
Formula for material requirements - so you calculate correctly
To calculate the required amount of gravel, first measure the bed. The third indication for determining needs still lacks the bulk density per cubic meter of the chosen type of gravel. This value is already part of the offer or can be found on the internet at Baustofflieferanten. The following formula gives the actual gravel requirements for your bed:
In order to cover a 5 m long and 4 m wide bed with Danube gravel 8-16 mm (1.42 t bulk density per m³) opaque, the following calculation results: 5 mx 4 mx 0.032 mx 1420 kg = 908.8 kg gravel requirement.
Include delivery costs
To calculate the costs, first multiply the purchase price per kilogram of gravel by the required quantity. In addition, there are the delivery costs, which can be considerable in view of the considerable weight. Sparfüchse among the gardeners rent a trailer and drive to the nearest gravel.
Tips
In order for the calculated amount of gravel to remain where it belongs, there must not be an adequate border around the bed. Even a simple lawn edge made of metal prevents the stones from spreading in the garden. Decorative and tasteful, a demarcation of natural stones highlights the pebble bed.
