A groundwork job for new lake construction involves comprehensive site preparation to establish a stable foundation for the project. This includes surveying and grading the site to ensure proper elevation and drainage, excavating the lake basin to the required depth and shape, and compacting the soil to prevent erosion and leakage. The groundwork team may also install geotextile liners or clay barriers for water retention and build inlet and outlet structures to manage water flow. Additionally, they prepare surrounding areas for landscaping, access roads, and utility connections. Safety and environmental compliance are prioritized throughout to minimize ecological impact and ensure a durable, sustainable lake structure.
