Downspout erosion at foundation — Barcelona, Catalonia
When a roof downspout empties directly at the base of the house without an extension or splash block, the concentrated flow of rainwater erodes soil along the foundation wall. Over time this carves a channel or depression that directs more water against the foundation, increasing the risk of basement leaks, crawl-space flooding, and even undermining of the footing. The constant wetting and drying cycle can also cause the surrounding soil to compact unevenly, leading to settlement cracks in walkways or patios nearby. A landscaper can regrade the eroded area, install downspout extensions or buried drain lines to carry water at least 4–6 feet from the house, and add erosion-resistant ground cover or rock beds to prevent recurrence.
Waarom dit veel voorkomt in Barcelona
Barcelona's private gardens concentrate in the upper districts (Sarrià, Pedralbes) and the hillside Tibidabo belt, where terraced plots and Mediterranean planting require specialist care. Rooftop terraces (terrats) and balcony greening are common in the dense Eixample, and water-efficiency rules increasingly govern irrigation under Catalan drought planning.
