Yes, you can reuse old mulch, but it’s important to check its condition first. If the mulch is still structurally intact, not overly compacted, and free from mould or disease, it can simply be fluffed up and topped with a new layer. Reusing mulch reduces waste and maintains soil protection. However, if the mulch smells sour, has visible fungal growth, or has broken down into fine particles resembling soil, it’s better to incorporate it into your compost or garden beds as an organic amendment and apply fresh mulch over the top.

Road base is a specific type of compactable material made from crushed rock mixed with fine particles. It's designed to create a firm, stable surface and is typically used under driveways, paths, and concrete slabs. Gravel, on the other hand, generally refers to loose stones or pebbles, which may or may not compact depending on size and shape. Gravel is more decorative and is often used as a surface finish, while road base serves as a strong foundation underneath structures. In many projects, both are used together—road base for support, gravel for aesthetic topping.

For a long-lasting gravel driveway, it's recommended to lay gravel to a total compacted thickness of about 100mm. This often requires multiple layers: a base layer of larger crushed stone, topped with smaller gravel to create a smooth surface. Each layer should be spread evenly and compacted well before adding the next. Proper preparation of the sub-base is crucial—grading and compacting the ground before adding gravel ensures stability and good drainage. Without adequate thickness and compaction, gravel driveways are more likely to develop potholes and uneven surfaces over time.

Using a weed mat or landscape fabric under decorative rocks is highly recommended to prevent weeds from growing through the rocks while allowing water to drain through easily. It also stops the rocks from sinking into the soil over time, helping them stay clean and visually appealing. Choose a permeable, UV-resistant weed mat for the best results. If installing in high-traffic areas or sloped spaces, ensure the mat is well-anchored to avoid shifting. While it won’t eliminate weeds completely, it will drastically reduce maintenance and keep landscaped areas looking neat longer.
