EXPOL QuickDrain is the no-scoria drainage solution made with recycled polystyrene aggregate.

The QuickDrain solution is designed for the economic removal of excess ground water in residential and commercial non-traffic applications.  It is ideal to be used in retaining walls, water logged backyards and gardens, and perimeter drainage around houses and sections.

QuickDrain comes ready to go. It is sold in 2.5 metre lengths and is approximately 200mm in diameter. Every 2.5m length of QuickDrain is supplied with one joiner, one cable tie and instructions how to cut, join and install.

QuickDrain Is an engineered drainage solution that provides a scoria-free alternative to traditional scoria drainage solutions, cutting installation time in half.

QuickDrain incorporates a recycled polystyrene aggregate that provides enhanced drainage performance, strength, filtration and longevity.

The QuickDrain solution is a faster and easier install than traditional drainage solutions.

Once buried the QuickDrain will last indefinitely (50+ years) as it is produced from HDPE plastic, recycled polystyrene and PET fibre, however the drainage performance will be dependent on the overall design.

What is R-Value?

An R-Value is a rating which measures how well insulation can resist heat flow. ‘R’ stands for thermal resistance.

  • R-Value level depends on a number of things such as the type
    of material, its density and thickness.
  • Higher R-Value = Better insulation.

System Components

EXPOL supplies joiners to connect one length of QuickDrain to another. EXPOL’s range of available components is listed below:

Straight Joiner

1 x straight joiner comes with every length of QuickDrain.

Y Joiner

Where you need to change direction and join one length of QuickDrain with two you can use a Y joiner.

Installation Instructions

  • QuickDrain comes in easy-to-handle 2.5 metre lengths. Each length comes with a QuickDrain Joiner and cable tie.
  • Dig your trench the same width as your QuickDrain and deep enough to allow a minimum of 200mm of soil coverage.
  • Simply clip the length together to achieve the required length for your project. Once the QuickDrain has been laid in the trench you are ready to start covering the QuickDrain.

Once QuickDrain is buried it will last 50+ years as it is produced from HDPE plastic, recycled polystyrene and PET fibre, however the drainage performance will be dependent on the overall design.

When laying QuickDrain please ensure it has a fall. Make sure it is directed to the lowest point of your property and is connected to a stormwater outlet. Exposure of QuickDrain to sunlight for prolonged periods should be avoided.
