Megaflo is a rigid, high-flow velocity panel drain designed for drainage of the aggregate layers within roads, from behind retaining walls or in sports fields. Megaflo has twice the inflow capacity and drains water 60% faster than 100 mm slotted round pipe. The Megaflo drainage system requires only a narrow trench so installation costs are significantly reduced. Because of its stiff structure and high flow velocity there is also less risk of siltation.

The Megaflo system has a corrugated panel supported by internal pillars along the length of the drain. This shape and structure gives Megaflo a high crush resistance whether the drainage system is used vertically or horizontally.



Good road drainage is essential to maintain roads at optimal performance levels. The Megaflo drainage system is a cheaper alternative to French drains, which use scarce natural resources. Megaflo halves the installation time required for traditional methods of road drainage making it ideal for projects with tight construction deadlines.


Megaflo is well suited to a range of landfill drainage applications because of its high compressive strength under normal and inclined loads. It is resistant to leachates present in landfill operations and allows for safe gas and leachate drainage even under extreme loading pressures.

Sports fields

Removing surplus water from sports fields quickly is important so play can resume as soon as possible. Using the narrow Megaflo drainage pipe allows the sports field surface to make a speedy recovery. With standard depths of 170 mm, 300 mm and 450 mm, Megaflo drains water more quickly than other systems.

Shotcrete walls & tunnels

Structures located below the water table may become unstable over time. Megaflo provides reliable drainage for construction projects like shotcrete walls and tunnels thanks to its nonwoven geotextile wrap. 


Megaflo is ideal for use in landscaping applications such as behind non structural retaining walls, under driveways and paths, as well as being the most effective system on the market for drainage of lawns and turf.


The Megaflo subsoil drainage system is manufactured in Australia from recycled materials. It is narrow in width making it easy to install and is stiff in the vertical axis. Geofabrics can supply installation equipment to ensure for a safe and rapid installation process.
The Megaflo system’s design simplifies the installation process, significantly reducing costs. It has a high crush resistance and an unmatched drainage response time. 


Megaflo panel drain requires a minimum cover of 300 mm for road applications and is suited for narrow trenches. Megaflo is supplied in rolls and is dispensed into the trench followed by the backfill which can be a well graded gravel or sand. Applications for Megaflo panel drains include roadside edge drains, under kerb drainage, cross drainage for highways, under drains for road widening, sports field/lawn drainage systems, vertical drainage behind retaining and shotcreting, leachate collection drains and mine tailings and heap leach drains.
