Everything You Need to Know About Decorative Gravels, Pebbles.

Decorative gravels, pebbles, and decomposed granite are versatile landscaping materials that can transform the look and functionality of your outdoor spaces. Whether you’re looking to enhance your driveway, pathway, garden beds, or water features, there’s a perfect solution for every need. Here’s a comprehensive guide to help you make informed choices and get the best out of these materials.

1. Are All Gravels and Pebbles Suitable for Driveways or Pathways?

Not all decorative gravels and pebbles are created equal. While most options are excellent for pathways and driveways, Scoria, a volcanic rock, is an exception. Scoria is too brittle to handle the weight and stress of vehicular or pedestrian traffic.

2. Which Gravels and Pebbles Are Best for Inorganic Mulch?

All gravels and pebbles can be used as inorganic mulch. For best results, it’s recommended to install a weed mat underneath the mulch. This ensures that the mulch remains clean and can be easily removed when necessary, such as when adding organic matter to the soil or installing irrigation systems.

3. What Gravel or Pebble Works Best for Natural Water Features?

If you’re designing a natural water feature, Random River Pebble is a popular choice. Its smooth, natural appearance complements the tranquil aesthetic of water features beautifully.

4. Do Gravels and Pebbles Have a Lifespan?

In general, decorative gravels and pebbles are incredibly durable and can last forever. The only exception is Scoria, which is softer and prone to degradation under heavy loads or regular vehicular traffic.

5. What Is Decomposed Granite (Deco Granite) Used For?

Deco Granite is a versatile and decorative gravel that’s perfect for creating durable driveways and pathways. Available in brown, pink, and gold hues, it can be stabilised and compacted to create a hard-wearing surface.

For best results:

• For pedestrian pathways, stabilise with 5% cement (1 bag per tonne of Deco® Granite).
• For driveways, use 10% cement (2 bags per tonne).
• Alternatively, stabilise with builders lime at 5% instead of cement.

6. Can Deco Granite Be Laid Over Existing Concrete?

No, laying Deco® Granite over concrete is not recommended. Concrete lacks flexibility, leading to potential cracking of the granite due to expansion and contraction caused by changes in temperature and moisture.

7. How to Lay Deco Granite

Proper installation is key to ensuring a long-lasting and aesthetically pleasing surface. Follow these steps:

1. Prepare the Base: Establish a suitable base layer.
2. Apply Stabilised Granite: Spread the stabilised Deco® Granite to a depth of at least 100mm.
3. Compact the Surface: Use a vibrating whacker plate for compaction. If dust blows out, lightly water the surface and compact again.
4. Level the Granite: Adjust the surface to achieve a level finish with a minimum cross-fall of 5% to prevent water pooling.
5. Finish the Surface: Lightly water and broom off excess material. Allow the surface to dry for 24-48 hours.
