DuraFlow Q Drainage Composite
DuraFlow Q is a three-dimensional composite product consisting of a drainage core and nonwoven geotextile for drainage application.
DuraFlow Q is used extensively to drain water or gas in various applications. In landfill engineering, DuraFlow Q serves three functions at once; filtration, protection and drainage, when installed directly above a geomembrane.
The ability of DuraFlow Q to passively relieve water pressure makes it ideal for drainage over buried structures and for road edge strip drain applications. The filter geotextile and the drainage core can be efficiently dimensioned to meet the required drainage capacity. DuraFlow Q is also used successfully as a drainage layer in the construction of buildings, tunnels and roofs.
Frequently Asked Questions
What is the difference between DuraFlow Q and DuraFlow?
DuraFlow Q uses a three-dimensional matrix core while DuraFlow T uses a biplanar net. The crush and flow rate data is different for both products, but in practice, they do the same job and are often interchangeable.
Will pressure on the DuraFlow Q reduce its flow capacity?
Yes to a certain degree. Refer to the data sheet (available in downloads section) for flow rates under various surcharge loads. In practice, the DuraFlow Q will still function with a very high standard stress applied.
