In groundwork terms, drainage refers to the systems and processes used to manage surface and subsurface water on or around a construction site. Effective drainage is crucial for preventing water accumulation, erosion, and instability in the soil, which can weaken foundations, cause structural issues, and lead to flooding.
Groundwork drainage design is often site-specific, tailored to the soil type, water table level, and expected precipitation or water flow in the area. Proper groundwork drainage ensures long-term site stability and is a foundational step in many construction projects.
