Buying Guide
Key considerations when choosing interlocking stones for retaining walls and borders:
- Material and weight: Lighter plastics are easier to install but may require more panels for stability; heavier blocks offer durability but require careful handling.
- Interlocking design: Snap-fit or no-dig systems reduce installation effort but ensure a level base for stability.
- Weather resistance: Look for UV resistance, frost tolerance, and moisture resistance to ensure longevity in outdoor conditions.
- Aesthetic: Stone-look vs. cobbled appearance; consider compatibility with your landscape style and color palette.
- Maintenance: Some options are washable and fade-resistant; others may show wear more quickly in high-traffic areas.
- Installation surface: Ensure a flat, compacted base (concrete, soil with a trench, or compacted sand) for best results.
- Modularity: For curved beds or irregular edges, modular panels facilitate customization without cutting.
