Soggy lawns and pooling water plague many Sevenoaks gardens, particularly those built on the heavy clay soils common throughout the Greensand Ridge. Professional drainage transforms unusable outdoor spaces into year-round havens.
Response within 24 hours
Clay-rich soil beneath Sevenoaks creates notorious drainage headaches for homeowners from Otford to Dunton Green. Victorian properties with their generous plots often suffer worst, where decades of compaction meets naturally poor-draining earth. Modern solutions range from simple French drains to comprehensive soakaway systems, each tailored to your garden's unique challenges and the local water table conditions.
Proper assessment begins with understanding your garden's natural water flow and identifying problem zones where rainfall accumulates. Installation typically involves strategic placement of perforated pipes, gravel channels, or cellular crates beneath your lawn, directing excess water away from vulnerable areas. The depth and complexity depend entirely on factors like your property's position on Sevenoaks' undulating landscape and existing hardscaping that might block natural drainage paths.
