Where do pebbles come from?

The smooth shiny stones you see in beautiful gardens are actually a by-product of years of natural erosion in exotic locales like China, Indonesia, Philippines and Vietnam. 

 These pebbles aren’t easily found or formed – there is actually a lengthy process to achieve the finished product. 

As rainwater washes away bits and pieces of mountain, these loose pieces of stone slowly (over thousands of years) make they’re way into mountain steams – they then follow the water to the ocean. 

The beauty is truly reflected by the process, the stones travel with the flow of water and over time lose their rough texture and sharp edges, they become the beautiful pebbles you have in your home today.

Where can stone pebbles be used?

  1. Rooftops

  3. Drainage
  4. Poolside
  5. Garden edging
  6. Ground cover
  7. Garden beds
  8. Pot Plants
  9. Around Firepit
  10. Around bathtubs


Garden Pebbles can be used on rooftops not only to create more visual appeal but also having stone pebbles spread several inches thick over a roof can help reduce heat as pebbles absorb and release heat. This will assist in protecting the roof from any cracking that may occur from sun exposure. 

Between stepping stones: 

You can strategically use exotic pebbles to define the area between your stepping stones, it is wise to choose a style of the pebble that either compliments or completely contrasts with your stepping stones. 

Using pebbles to define your walkway or pathway will add more texture and movement to space.

Garden edging:

Landscaping Pebbles can be used to edge around your garden space, especially the larger size 90-120mm or 100-150mm pebbles can be ideal for this as they create a natural border and define your garden space. 

Ground cover:

Using decorative pebbles as the ground cover can be a smart way to attend to any neglected areas, for example, you could cover unwanted lawn or an eroding pathway. First, matt the area and then spread the pebbles evenly about two courses thick, we recommend a 50mm coverage for these types of areas.

Garden beds:

Using pebbles for garden beds can really reduce the chances of losing any moisture. This is beneficial to plants as soil retains a higher level of moisture as well as a reduction in watering. Not to mention they create a beautiful area around your plants which can be very visually pleasing. 

Pot Plants:

Pebbles make for a stunning surround around pot plants, not only this they also retain all the benefits mentioned in the previous point, you will see the area experience a higher water retention rate as well as sustainability.

How to install garden pebbles?

Weeds can be problematic with pebbles, however, a thick layer should do the trick in preventing them from growing through. You could also try a treatment of Roundup before laying the pebbles.

Adding underlay between the rocks and the soil creates a weed barrier that helps prevent weed seeds from touching the soil. Choose landscape fabric or black plastic as the underlay. Plastic creates a stronger weed barrier than landscape fabric, but water won’t pass through it to feed the bushes’ roots; an option is to use the plastic but leave holes in it around the bushes.

How to Calculate the coverage of the pebbles?

Pebble coverage is affected by a number of factors, including the coverage area, depth of cover shape of the pebbles and size. It can be tricky to calculate Garden pebbles as they are in some part, multiple sizes however what we have done is we have laid enough pebbles on each square meter and found an accurate formula to help you find out how much you would need. Even though we believe we have created an accurate formula, it is important to understand that it is impossible to get 100% accuracy so please keep in mind this calculation is still approximate. 


To manage your pebbles quantities correctly: 

1. Use an underlaying material – typically a less expensive pebble such as blue metal (or one that is a similar colour) can be layed to cover a significant amount of depth and then you may add your feature pebbles on top. This works best when the area you are covering is not going to be getting any foot traffic as foot traffic may allow the base pebbles to become visible. 

 2. Mix sizes – smaller pebbles offer much better coverage than larger pebbles. You can strategically mix large and small pebbles together as the smaller pebbles will fill gaps between larger pebbles and allow you to spend less to achieve a visually pleasing result. 

3. Play with shapes and sizes – some pebbles give better coverage per square metre than others. This usually comes down to the shape and size of the pebble. Smaller pebbles typically allow for a better spread and coverage than larger pebbles and this should be factored into your numbers. 

4. Insert your pebbles into grout – this allows for a better coverage per square metre and is a smart idea for surfaces that will have foot traffic. 



 You should now have a solid understanding of garden pebbles, where they come, how they can be used and an approximate guide to calculate coverage.
