At Aggregate Superstore, we believe every outdoor space — whether a small garden, a large driveway, or a landscaped courtyard — deserves to shine with character, texture, and style. One of the most effective ways to achieve this is by learning how to lay decorative aggregates. With the right preparation and materials, you can completely transform your outdoor space into something truly eye-catching.
In this guide, we’ll walk you through every step — from planning and groundwork to laying and maintaining your aggregates — so you can create a standout garden or driveway confidently. Whether you’re a professional landscaper or a DIY enthusiast, this comprehensive approach ensures lasting results.
Why Choose Decorative Aggregates?
Decorative aggregates are not only visually appealing but also highly practical. They’re versatile, low-maintenance, and available in a wide variety of colours and textures. When you understand how to lay decorative aggregates correctly, you gain control over the finished look and durability of your project.
At Aggregate Superstore, we stock an exceptional range of aggregates — from classic pea gravel and crushed slate to marble chips and decorative stones — perfect for gardens, pathways, and driveways. We make it simple for you to find the ideal solution for your space, budget, and design preferences.
Step 1: Planning Your Space
Before you rush to buy materials, take time to plan your layout carefully. Consider the overall style of your property and what you want your garden or driveway to convey — elegance, modern minimalism, rustic charm, or something else entirely.
Start by measuring the area you want to cover. This will help you calculate how much aggregate you’ll need. Our Aggregate Superstore calculator tool (available on our website) makes this easy and ensures you purchase just the right amount — no wastage, no shortage.
Step 2: Preparing the Groundwork
Knowing how to lay decorative aggregates properly begins with solid groundwork. Remove any existing grass, weeds, or debris, and dig to a depth of at least 50–75 mm depending on the use (a garden path will require less depth than a driveway).
Next, install a high-quality weed membrane. This prevents future weed growth and keeps your aggregates clean and tidy. At Aggregate Superstore, we supply professional-grade membranes that are durable and easy to install — perfect for DIY projects.
Step 3: Edging for a Defined Finish
Edging plays an important role in keeping your aggregates contained and providing a clean, professional look. Use timber, metal, or stone edging depending on your aesthetic preference. A sturdy edge ensures your aggregates stay neatly in place, even after heavy rain or foot traffic.
This step is often overlooked, but our experts at Aggregate Superstore always emphasise it when advising customers on how to lay decorative aggregates effectively.
Step 4: Adding a Sub-Base (for Driveways and Paths)
If you’re laying aggregates for a driveway or an area that will experience regular vehicle use, you’ll need a solid sub-base layer. We recommend using MOT Type 1 or crushed limestone compacted thoroughly to create a stable foundation. Without it, your decorative aggregates may shift or sink over time.
For light garden paths or seating areas, a thinner layer may suffice, but always aim for stability before applying your final decorative layer.
Step 5: Laying the Decorative Aggregates
Now comes the exciting part — adding your chosen aggregates. Spread them evenly across the prepared area using a rake, aiming for a consistent depth of about 40–50 mm for most projects. Too thin, and you’ll expose the underlay; too thick, and the surface may feel uneven underfoot.
At Aggregate Superstore, we provide high-quality aggregates that are pre-washed and graded for consistency. This makes your installation smoother and the final look more polished. Whether you’re working with golden gravel, white marble chippings, or plum slate, the method remains the same — even distribution and careful levelling are key.
Step 6: Compact and Settle the Surface
Lightly compact the surface using a garden roller or tamper. Avoid heavy compaction, as you want your decorative aggregates to maintain their natural texture and appearance. Over the first few weeks, the stones will naturally settle — topping up where necessary will ensure long-term evenness.
Knowing how to lay decorative aggregates correctly at this stage helps prevent uneven surfaces and long-term movement.
Step 7: Finishing Touches and Maintenance Tips
Once laid, take a moment to admire your handiwork. You’ve created a stunning, low-maintenance outdoor surface that will last for years.
Regular upkeep is minimal. Simply rake the surface occasionally to redistribute stones evenly, and remove debris or fallen leaves to preserve the colour and texture. A well-laid decorative aggregate surface doesn’t just look impressive — it also improves drainage and reduces maintenance time compared to lawns or paved areas.
At Aggregate Superstore we provide everything you need to maintain your new surface — from replacement bags of matching aggregates to top-quality landscape fabric and edging materials.
