What is the main purpose of drainage systems in construction?

The main purpose of drainage systems in construction is to manage excess water and prevent structural damage. Proper drainage is crucial to diverting water away from buildings and other structures. When excess water accumulates around a structure, it can lead to various issues such as soil erosion, foundation settlement, and water infiltration into basements or crawl spaces. By effectively channeling water away from the property, drainage systems help maintain structural integrity and longevity, reducing the risk of costly repairs and ensuring a safe environment.

While enhancing aesthetic appeal, increasing property value, and facilitating landscaping irrigation are valuable considerations in construction, they do not represent the primary function of drainage systems. The focus of drainage is fundamentally about the effective management of water to protect buildings and maintain their foundations from the detrimental effects of excess moisture.
