Installing soakaways here requires understanding both soil percolation rates and the specific drainage challenges facing properties from Crayford's newer estates to Sidcup's established roads.
Testing infiltration rates determines soakaway sizing - crucial when dealing with London clay. Perforated chambers wrapped in geotextile membrane prevent silt blocking the system. Connecting downpipes and surface drains creates comprehensive water management. Each installation accounts for garden slope, existing utilities, and proximity to foundations.
