The TerraTex® Non-Woven 1200 geotextile range is a 100% polypropylene staple filament that is highly needled for the use of a wide range of geotechnical applications including separation, filtration and reinforcement procedures. TerraTex® PP Non-Woven 1200 geotextile is manufactured according to ISO 9001 quality standards. The product is wrapped in highly UV stable outer wrap and may be left outside, onsite or for later use provided the wrapper is not removed prior to deployment and use. It is recommended installation occur within a month of delivery.
TerraTex® Non-Woven geotextiles enhance the performance and design life of granular layers by providing the filtration and separation functions. Typical uses for TerraTex® standard geotextiles include ground stabilisation (between the sub-base and subgrade) around drainage materials and the protection of impermeable liners.

Terratex® prevents intermixing of granular materials and soils
TerraTex geotextiles provide an effective solution for constructing a stable granular layer over soft foundation soils. When stone is placed directly on a soft subgrade, the imposed load often causes intermixing of two layers. This results in contamination of the stone layer and a resulting loss in bearing strength, surface rutting and deformation at the sub-base/subgrade interface.
Terratex® prevents the ingress of fines into drainage media
Whether it’s a granular drain or a geosynthetic alternative such as an open TerraDrain unit, TerraTex standard geotextiles are ideal for preventing the ingress of fines.
Balancing the cost/quality of the drainage stone with the level of protection that it will demand is part of the engineering process. The broad TerraTex geotextile range provides grades for use with inexpensive, aggressive stone as well as for expensive, more-rounded alternatives.
Coastal and Waterway Engineering
The hydraulic and filtration properties of TerraTex® standard geotextiles makes them highly effective in replacing traditional filter layers. Typically, a single layer of geotextile can replace a succession of stone filter layers. A single bedding layer of stone is laid on the geotextile and this is followed by the rock armour. See an example of TerraTex® of being used for this application in the construction of a new water storage at Euroa, Victoria.
