Understanding why gardens waterlog
Gardens waterlog when water cannot soak away. Heavy clay soil holds water, while compacted soil blocks it. A high water table or a lot of paving can add to the problem.
Blocked pipes and gullies can also play a part. Meanwhile, rain from roofs may drain into the garden if downpipes fail. Finding the cause comes first.
A good fix starts with a plan. Walk the garden after rain and note where puddles form. Take photos and measure the area. This helps a contractor give a clear quote.
Diagnosing your garden drainage
Watch where the water collects after rain. Dig a small hole and fill it with water. If it takes a long time to empty, the soil drains poorly.
Check gullies, downpipes and any soakaway. A camera survey can show if pipes are damaged. Because several causes can combine, check each one.
Solutions for garden drainage
Simple fixes include aerating the lawn, adding organic matter and building raised beds. For larger problems, a land drain or French drain can carry water away. A soakaway can store water so it can seep into the ground.
Permeable paving lets rain soak in instead of running off. Each method suits different soils and sites. Ask a qualified professional for advice, since a bad design can move the problem to a neighbour.
Small gardens may only need a soakaway or better soil. Large or sloping sites may need a land drain that runs to a safe outlet. Whichever you choose, keep the outlet clear and check it each year, because silt can block it.

Legal and planning considerations
Some drainage work needs permission or approval, since rules cover digging near sewers. Digging near sewers or changing how water leaves your land may be covered by rules. Read our guide to building regulations for drainage.
Take care not to send water onto a neighbour’s land, because that can cause disputes. Check with your local council and your water company before you start. They can tell you what applies.
