Transforming gardens and driveways into stunning outdoor spaces can be easily achieved with the incorporation of decorative aggregates, pebbles, and cobbles. These versatile and visually appealing materials not only enhance the aesthetic appeal of outdoor areas but also offer a multitude of practical benefits. From adding texture and colour to providing a low-maintenance and durable alternative to traditional paving, decorative aggregates seamlessly complement existing paving, creating a harmonious and captivating landscape that captures the essence of nature's beauty. Whether used as focal points or as a cohesive design element, the integration of decorative aggregates elevates outdoor spaces to new heights, making them a delightful choice for homeowners and landscape enthusiasts alike.

Here's a few frequently asked questions and answers about decorative aggregates, pebbles and cobbles:

How much does a 20kg bag of stones cover?

The coverage area provided by a 20kg bag of decorative aggregates can vary depending on the size and type of the aggregates. For example, a small gravel will cover a greater area than a larger sized pebble or cobble. Generally, a rough estimate is that a 20kg bag can cover approximately 0.2 - 0.3 square metres of space, assuming a typical thickness of 2-3cm. For a full tonne in polybags, aim for around 10-15 square metres coverage, again depending upon aggregate size. Note that some products are sold in 20kg bags with 50 on a pallet to give a tonne and others are sold in 25kg bags with 40 on a pallet to give a tonne. Weights and measurements are nominal. 

What weight is a bulk bag of stones?

A bulk bag of stones typically weighs between 850 kilograms and 1 tonne, making it an efficient and convenient option for larger-scale landscaping projects. These robust and heavy-duty bags, often referred to as "tonne bags" or "bulk bags," are designed to hold a substantial amount of material while ensuring easy transportation and handling. Whether you're renovating a garden, constructing a driveway, or embarking on a commercial landscaping endeavor, a bulk bag of stones provides a generous supply of aggregate that simplifies the process and offers flexibility in meeting your project's requirements.

What do you put under garden stones?

When installing garden stones, it is essential to prepare the ground properly by using a suitable base material. One common practice is to put a layer of landscape fabric or geotextile membrane underneath the stones. This fabric acts as a barrier, preventing weed growth and minimising the risk of stones sinking into the soil over time. Additionally, a layer of compacted hardcore or crushed stone can be laid as a stable and level base for the garden stones. This base material provides structural support and helps with drainage, ensuring that the surface remains even and durable. By incorporating these preparatory measures, you can create a solid foundation that not only enhances the aesthetics but also prolongs the longevity of your garden stone installation. The key to laying decorative stone is not to have the stone too deep as this makes it difficult to walk on. Laying on MOT Type 1 and then only using a layer of stone 2-3cm in depth is usually ample for a pathway.

What garden pebbles are suitable for walking on?

When it comes to selecting garden pebbles that are suitable for walking on, it's important to consider their size, shape, and texture. Smooth, rounded pebbles are a good choice when small - usually graded up to 20mm, as they provide a comfortable walking surface. Pebbles with a larger diameter above 25mm can be slighly uncomfortable as a pathway material. Similarly, angled decorative aggregate makes a good pathway surface. 

What area will a 25kg bag of pebbles cover?

The coverage area provided by a 25kg bag of pebbles can vary depending on the size and thickness of the pebbles, as well as the desired depth of coverage. As a rough estimate, a 25kg bag of pebbles can typically cover around 0.25 to 0.4 square metres of space when applied at a thickness of 2-3cm. However, it's important to note that different types of pebbles can have varying coverage. For a full tonne in polybags, aim for around 10-15 square metres coverage, again depending upon aggregate size. Note that some products are sold in 20kg bags with 50 on a pallet to give a tonne and others are sold in 25kg bags with 40 on a pallet to give a tonne. Weights and measurements are nominal. 

Can you lay pebbles on soil?

Yes, pebbles can be laid directly on soil, but it is important to properly prepare the area beforehand to ensure a stable and long-lasting installation. Firstly, it is recommended to clear the area of any vegetation, debris, or weeds. Then, it can be helpful to create a border or edging around the desired area to contain the pebbles and prevent them from spreading. Adding a layer of landscape fabric or geotextile membrane over the soil before laying the pebbles can help inhibit weed growth and provide a barrier between the soil and the pebbles. This fabric allows for water drainage while preventing the pebbles from sinking into the soil. Additionally, compacting the soil and ensuring it is level can help create a solid base for the pebbles. By taking these steps, you can successfully lay pebbles on the soil, creating an attractive and low-maintenance surface in your garden or landscaping project.

What do you put down before laying pebbles?

In preparation for laying pebbles, it is crucial to undertake proper groundwork to ensure a successful and durable installation. Firstly, determine what the area is to be used for. If it's a planting bed and your are using the pebbles as a decorative mulch, it is recommended to employ a weed barrier or landscape fabric as a protective layer over the area. This barrier effectively prevents weed growth and safeguards against pebbles sinking into the soil.

If instead, you plan to use the decorative pebbles on a pathway or even a driveway, then it is necessary to establish a sturdy foundation by introducing a base layer consisting of MOT Type 1, crushed stone or a similar aggregate material. This base layer facilitates efficient drainage and enhances stability, guaranteeing that the pebbles remain level and securely in place. For a pathway, it's best to use at a compacted depth of 100mm and for a driveway, 150mm. By meticulously attending to these preparatory steps, you can confidently proceed with laying the pebbles, creating an appealing outdoor space that will withstand the test of time.

Which decorative stone should I use for a driveway?

Opting for a hard and durable stone is crucial to withstanding the weight of vehicles and regular traffic when deciding on an aggregate for a driveway. Crushed granite, limestone, flint gravels or basalt are popular choices due to their strength and ability to withstand heavy loads. Additionally, considering the aesthetics, choosing a stone that complements the overall style of your property is important. It is also advisable to select stones that have good interlocking properties to provide a stable surface and minimise movement. Some stones are not suitable such as those larger than 20-30mm, highly decorative polished or flat pebbles and crushed slate.

Do stone sizes vary within a bag of decorative stone?

The sizes of stones in a bag of decorative stones can indeed vary within the tolerances set by British Standards. The grading of natural stone, especially in accordance with British Standards, follows a specific procedure that employs sieve measurements. This process entails passing the stones through a series of sieves with different mesh sizes. Each sieve retains particles within a specific size range, effectively controlling the material falling into those particular categories. The resulting data is then utilised to assign a grading designation to the stone. It is important to note that due to this process, it is not uncommon for a stone to meet the graded size in one direction but exceed it in another direction, depending on how it enters the sieve. Such variations should be expected from time to time, as they are inherent to the grading process and within the tolerances outlined by British Standards.
