Aztex Woven Geotextiles

Woven geotextiles are used for separation, filtration and reinforcement.

As a separation layer the geotextile prevents the loss of stone into the subgrade.

As a filtration layer the geotextile prevents soil fines entering the drainage media.
A geotextile wrapped drain has around twice the life expectancy of a conventional
French drain.

As a reinforcing layer the geotextile can save not only the initial loss of the fill into the
sub-grade but also offer a reduction in the overall construction thickness.

Aztex Standard Grades

A range for separation and drainage applications that will cover the majority of
site conditions. The numbers used in the standard grades represent the CBR push
through resistance of the geotextile.

Also available:
Aztex Mini Pack, 4.5m x 10m.

Aztex Highflow Grade

Aztex Highflow Grades are used where a high water flow is expected to flow through the geotextile, especially adjacent to a watercourse.

Aztex Reinforcing Grade

A new substantially improved geotextile for use where the geotextile must separate and reinforce the base of a construction.

The economic argument for the use of Aztex Woven Geotextiles

The use of Aztex Geotextiles as separators brings two main benefits:

1. The subgrade material onto which stone is laid is often not sufficiently solid to prevent some of this sinking into it as soon as traffic passes above. The American Federal Highways Administration estimates that when the subgrade CBR strength is 2%, between 15% and 40% of the design thickness of stone could be lost into the subgrade.
   There is no way to retrieve that stone once pushed down, it will never play any part in supporting traffic loads. Not only does it mean that money is being wasted on expensive aggregates but the road is being trafficked on up to only 2/3 of the thickness it needs to be as an engineering solution. This will result in the life expectancy of the road being reduced.
2. Aztex Geotextiles act as a support to the stone preventing it from being pushed down into the subgrade. If 500mm of stone is used in conjunction with our Geotextile you can count on 500mm of stone for the total life of the road. As well as extending the life of the road it will cut construction costs. Assuming stone costs £9.00 per tonne, every 100mm of lost stone will cost £2.00/m2 (this does not include the time cost).

Who can justify or afford this waste!!
