Calculating pebble requirements
Here is a quick guide to how many pebbles you will need to lay one square metre.
|Square Metre Coverage (1 layer)||Square Metre Coverage (2 layers)|
|10mm – 30mm = 50kgs||10mm – 30mm = 110kgs|
|30mm – 50mm = 70kgs||30mm – 50mm = 150kgs|
To keep your pebble quantities to a minimum:
Use a base material
You can use an underlay of a less expensive base pebble (the same or similar colour) and lay the feature pebbles on top. However, this should only be done in areas where pebbles are not going to be walked on as this mixes the two types of pebbles together and the base material becomes visible.
Mix pebble sizes
Larger pebbles do not offer as much coverage as smaller pebbles. You can mix large and small pebbles together, as the smaller pebbles fill the gaps between the larger stones.
Choose specific shapes and sizes
Flatter stones give better coverage per square metre than rounder stones, and smaller pebbles give better coverage per square metre than larger stone.
Lay your pebbles in grout
This gives you a greater coverage per square metre and is a good idea for areas you walk on.
