Benefits of Drainflo®

Superior drainage and filtration

Drainflo® products have a specially designed slot pattern to maximise drainage and enhance product strength. Moreover, they can come with custom-made Cirtex® Filter sleeves that have been designed to protect subsoil drains from sedimentation.

Durability and strength

After almost 50 years in the New Zealand market, these products have truly stood the test of time. This is why they’re IANZ accredited and verified by ISO 9001 certification. They are also independently verified by Bureau Veritas to meet the SN6 and SN10 stiffness rating.

Flexibility and range

The sheer range of product options means that you have a choice of diameter, length, stiffness and filtration to suit your particular needs, whatever they are. Should you choose, you also have the option of the Drainflo® smooth range, which has 50% higher flow rates – ideal for low gradient or high volume applications.
