In landscaping, “interlock” typically refers to interlocking pavers or stones used in hardscaping projects. These materials are designed to fit together seamlessly, creating durable surfaces for patios, walkways, driveways, and retaining walls. Here are some key points about interlock in landscaping:

1. Durability: Interlocking pavers are known for their strength and resilience, making them ideal for high-traffic areas. They can withstand the elements, including rain, snow, and UV exposure.
2. Aesthetic Appeal: Interlocking pavers come in various shapes, sizes, colors, and textures, allowing for creative design possibilities. They can enhance the overall look of a landscape and complement other features.
3. Flexibility: Unlike concrete slabs, interlocking pavers can shift slightly without cracking, making them a more flexible option for outdoor surfaces.
4. Easy Maintenance: Individual pavers can be replaced if damaged, making repairs straightforward. Additionally, they often require less maintenance than traditional concrete surfaces.
5. Permeability: Some interlocking systems are designed to be permeable, allowing water to drain through the joints, which helps reduce runoff and promotes groundwater recharge.

Overall, interlocking pavers are a popular choice in landscaping for their practicality and aesthetic versatility.
