Prepare the Site and Lay the Sub-base

What happens here
Before any construction begins, the site must be thoroughly prepared. This involves clearing the designated area of any existing vegetation, debris, or old structures. Using a string line and stakes, accurately mark out the boundaries of the patio, outdoor kitchen, and fire pit areas according to your approved design. Excavate the soil to the required depth, typically 8 to 12 inches, to accommodate the sub-base, bedding sand, and pavers. Ensure a slight slope (approximately 1/4 inch per linear foot) away from the house or any structures for proper drainage. Lay down a layer of geotextile fabric over the excavated area to prevent soil migration and weed growth. Then, spread a thick layer of crushed stone (e.g., 3/4-inch crushed gravel) to form the sub-base. This layer must be compacted thoroughly using a plate compactor in multiple passes until it is firm and level. This stable and properly drained foundation is crucial for the longevity and stability of the entire outdoor living space.
Goal: Create a stable and properly drained foundation for the patio
