Drainage Solutions - Stop Flooding, Erosion and Foundation Damage for Good

Sydney's clay-heavy soils, steep blocks and intense East Coast Low downpours make drainage one of the most under-built parts of the average home. We see the same patterns across the harbour suburbs, Hills District and Central Coast - water tracking under slabs, sandstone cuts weeping into garages, retaining walls bulging because subsoil drains were never installed, and stormwater pits sized for 1990s rainfall events that now overflow every storm.

Tradetek's licensed plumbers design drainage to AS/NZS 3500.3 and local council DCPs (Northern Beaches, Hornsby, Ku-ring-gai, Sutherland, Central Coast and others). Every job starts with a site assessment - levels, soil type, existing pit and pipe layout, downpipe flows, neighbour runoff entry points - so the system we quote is sized for your actual rainfall load, not a generic 100mm spoon drain.

Typical work includes stormwater pit and pipe upgrades, French drains and slot drains around slabs and pools, agricultural (ag) pipe behind retaining walls, charged stormwater lines for tank connections, channel drains across driveways, soakwells where council allows, and easement drainage where neighbour runoff is a legal dispute. We coordinate with surveyors and structural engineers when a job needs certification for council or insurance.

Most residential drainage upgrades are completed in 1-3 days with a mini-excavator and finished off with reinstated turf, pavers or concrete. You receive as-built drawings, photos of every buried connection, and a workmanship warranty in writing - critical if you ever need to claim on home insurance or sell the property.

We work across Sydney metro, Northern Beaches, North Shore, Eastern Suburbs, Inner West, Hills District, Sutherland Shire, the Central Coast and Newcastle. After-hours emergency response is available for active flooding situations.
