Draintube Geocomposites

The aztex draintube range of geocomposites can be used in the following applications:

• Drainage of surface rainwater and biogas - aztex draintube FT
• Drainage of leachate on slopes - aztex draintube UV2
• Drainage of infiltration water under the geomembrane - aztex draintube FT

Both the draintube FT and UV2 are designed specifically for each project using software developed by an independent laboratory. Not only do they offer drainage, they reinforce the mechanical protection of the geomembrane.

Draintube's Environmental Savings

When the aztex draintube is used as an alternative to a typical granular drainage layer of 300mm thickness it is possible to make a saving of 162 lorry loads of material. The typical example below illustrates the calculations.

300mm gravel layer V 7,500/m2 of aztex draintube
(Plus geotextile) (1 load of aztex draintube*)

Gravel layer (300mm deep) for 7,500/m2 = 7,500 x 0.3 = 2,250/m3 Gravel

Gravel weight 1.8tonne per /m3

2,250 x 1.8 = 4,050/tonnes

Summary of Environmental Savings

• Potentially massive savings in aggregate and haulage
• No additional requirements for separator geotextile above granular layer as the aztex draintube has a geotextile layer as part of the geocomposite
• CO2 reduction via dramatical reduction in haulage requirements and excavation plant machinery
• Less on site digging requirements means less disturbance to eco-systems.
