Like any project, the quality of your hardscaping depends a lot on the materials you choose. The right materials will bring your vision to life with lasting beauty and durability, while the wrong ones can lead to disappointing results.
Aggregates - like sands, gravels, and stones - play a major role in hardscaping. They form the foundation of many outdoor designs and can make a huge difference in both appearance and longevity, so it's important to get the choice right.
At Wright Readymix, we've spent years helping people choose the right aggregates for all kinds of projects, and we know what works best. Read on for our guide to making the most of aggregates in hardscaping, plus some tips for picking the perfect type for your project!
1. Pathways and Walkways
Pathways are one of the first things people notice in a garden, so why not make them a standout feature? For a smooth, colourful look, consider using smaller stones like pea gravel - its mix of natural hues and soft texture creates a charming effect. If your path will see a lot of foot traffic, crushed stone is a sturdy option that compacts well, giving you a durable, stable surface that stays put.
Don't forget to add an edging material before laying down your chosen stones; this will keep everything in place and save you from having to rake it back into shape.
Recommended aggregates:
- Gravel provides a stable, well-draining surface that's easy to walk on. Pea gravel gives pathways a natural look and is durable for foot traffic.
- Crushed stone is a tough and reliable choice for high-traffic paths, providing a stable and attractive surface.
2. Patio Bases
If you want your patio to last, starting with a solid base is key! Aggregates are perfect for creating a stable foundation as they provide excellent drainage and prevent your patio from shifting or sinking over time.
A 4-6 inch layer of compacted aggregate works well to keep pavers or concrete level and steady. This method is especially helpful in areas with freeze-thaw cycles, as the aggregate helps reduce movement and keeps everything in place.
Recommended aggregates:
- Limestone compacts well, creating a solid base that won't shift, which is essential for supporting pavers and patios.
- MOT Type 1 is a mix of crushed stone and aggregate fines that forms a dense, level surface ideal for patio foundations.
3. Retaining Walls
Angular gravel and limestone make great backfill choices since the irregular shapes lock together, preventing movement and shifting. Using aggregate also helps with water drainage - an important factor to avoid water buildup and protect your wall from damage. For even more stability, consider adding a layer of fabric between the soil and aggregate.
Recommended aggregates:
- Gravel is ideal as a backfill for retaining walls, as its angular shape helps lock it in place, supporting the wall while allowing water drainage to reduce pressure from soil.
- Limestone also works well for backfill due to its compatibility and stability, helping prevent soil erosion around the wall.
4. Driveways and Parking Areas
Tough, rough aggregates like crushed granite or larger crushed stone are excellent choices for high-traffic areas like driveways and parking pads. They hold up well under heavy loads and compact tightly, making them resilient against weathering and regular vehicle use. To make sure your driveway stays smooth and free from ruts, start with a well-compacted sub-base layer of aggregate, followed by a top layer of smaller stones or gravel for a stable, long-lasting surface.
Recommended aggregates:
- Crushed granite is durable and attractive - perfect for driveways that need to handle heavy loads.
- Crushed stone adds solid structural support and helps prevent ruts and potholes.
5. Water Features and Drainage Solutions
Aggregates are a great choice for creating beautiful water features and managing landscape drainage. Stones like slate and pea gravel work wonderfully in ponds, fountains, and dry creek beds, adding a natural look while helping water flow smoothly to prevent stagnation. These stones are also excellent for French drains, guiding rainwater away to keep pathways dry and prevent soil erosion.
Recommended aggregates:
- Slate brings a natural, decorative touch to water features.
- Pea gravel is perfect for drainage solutions and helps prevent soil erosion.
Tips for Choosing the Right Aggregate
Not quite sure which aggregate is right for your project, or tackling something we haven't mentioned yet? Here are a few tips to help you decide:
- Functionality: Each aggregate offers different benefits, so look into which would best suit your requirements. For example, crushed rock provides stability for load-bearing surfaces, while pea gravel adds a decorative touch.
- Drainage Needs: Good drainage is essential in many hardscaping projects, so if needed, choose aggregates that help manage water flow and prevent pooling.
- Aesthetic Preferences: Aggregates come in various colours and textures - pick the ones that match your design vision for a cohesive look.
- Maintenance: For high-traffic areas, go for durable aggregates that require minimal upkeep, as this will save you time in the long run.
With these factors in mind, you'll find the perfect fit for your project!
