How to get patio drainage right: Experts explain everything you need to know
Briefly

A well-designed patio drainage system is crucial to prevent water accumulation on the surface of patio pavers, which can render the space unusable. Experts emphasize the importance of incorporating effective drainage measures, including sloped surfaces and permeable layers, to channel water efficiently. Without proper drainage, issues such as water damage, structural problems, and safety hazards arise, leading to uneven surfaces and increased injury risks. Investing in easy and straightforward drainage systems during patio design ensures longevity and usability, making it a vital step in landscaping projects.
Effective patio drainage begins with the slope, is reinforced by permeable layers, and often requires integrated drainage systems to channel the water to a suitable outfall.
Standing water can seep into the joints between the patio slabs or beneath the surface, eroding the sub-base and causing the slabs to sink, heave or become uneven.
