What is the primary purpose of proper drainage around a building site?

The primary purpose of proper drainage around a building site is to prevent wet basements and erosion. Effective drainage systems manage the flow of water away from the foundation of a building, which is crucial for maintaining structural integrity. When water accumulates around a foundation, it can lead to increased hydrostatic pressure, which may cause leaks, mold growth, or even structural damage over time. Additionally, proper drainage minimizes soil erosion, which can undermine nearby structures and landscaping. By directing rainwater and runoff away from the building, it ensures a safe and stable environment, protecting both the property and its inhabitants.
