French Drains That Work, Installed by The Plumbing Paramedics
Does your yard flood every time it rains? Seeing water pool near your slab or patio? A French drain may be your best fix, and it needs to be installed right the first time.
What is a French Drain?
A French drain is a subsurface drainage system that collects and redirects water away from areas where it causes damage, like soggy lawns, shifting retaining walls or saturated footings. It consists of a slotted or perforated pipe buried in gravel, usually wrapped in geotextile fabric, and is designed to use gravity to remove water from the problem zone.
French drains are not just trenches with gravel. They are engineered systems that require proper slope, flow, and connection to legal discharge points. They are a proven solution for:
- Sloping blocks
- Saturated soil
- Retaining wall seepage
- Pool and shed zones
- Backyards without stormwater mains access
How French Drains Work
- Water seeps into the gravel trench from the surrounding soil
- Water enters the perforated pipe, which runs at a gentle downward slope
- The pipe carries water away to a drainage pit, dispersion trench or legal outlet
- The geotextile fabric prevents sediment & root intrusion
- Topsoil or turf is laid back over the system for an invisible finish

What Sydney Locals Say About Us
All Drainage Relies Upon Fall
Correct fall is critical. A French drain must fall at a minimum of 1% (10mm per metre) or water will stagnate inside. If the drain is too shallow, backfilled incorrectly, or laid uphill, it fails.
We calculate fall using laser levels and drainage maps to ensure your system complies with AS/NZS 3500 and local council regulations. If the outlet point is lower than your boundary, we’ll connect to a stormwater pit. If there’s no council connection available, we’ll engineer a legal dispersal method like a soakwell or absorption trench.
Where We Install The Most French Drains
We work across The Hills District, Blacktown, and Greater Western Sydney, especially in acreage and sloping blocks in:
- Dural: high clay content, poor natural absorption
- Kenthurst & Glenorie: slope management and retaining wall protection
- Castle Hill & Rouse Hill: modern infill lots with poor backyard runoff
- Cherrybrook & Bella Vista: hard-surfaced landscapes with poor fall
Signs You Need a French Drain
- Pooling water after light rain
- Soggy turf or dying plants
- Damp rising through paving or slabs
- Water running from neighbouring property
- Seepage from retaining walls
- Water entering under doors or garages
