A solid base layer is crucial for the long-lasting performance of granite cobblestone pavers. The first step involves excavating the area to a depth that accommodates both the pavers and the base material. The typical depth ranges from 150mm to 200mm, depending on soil conditions and anticipated load. Once the area is excavated, it is essential to level the ground to ensure uniformity across the surface. This prevents uneven settling of the pavers over time.
Selecting the right base material will significantly impact the durability of the installation. Crushed rock or gravel is commonly recommended due to its ability to provide excellent drainage and stabilisation. The aggregate should be free from large debris and organic materials to promote effective compaction. When laying the base material, it is advisable to spread it in layers, compacting each layer adequately before adding the next. This practice establishes a strong foundation that can withstand the weight of the pavers and any surface loads expected in the future.
Incorporating drainage solutions into the design can enhance the longevity of the installation. Installing drainage pipes or French drains at strategic points will channel excess water away from the pavers. Additionally, using permeable materials in the surrounding landscape can absorb and redirect water effectively. These measures help maintain a stable foundation and contribute to the overall functionality of the paved area.
