High quality geotextile

Specifically developed to respond to the installation challenges of geotextile DuPont™ Typar® products are a breakthrough of importance comparing with other traditional construction techniques.

Unique properties

DuPont™ Typar® is composed of thermally bonded continuous polypropylene filaments. The fibre extrusion process produces thousands of superfine continuous filaments, which pass through a DuPont patented “pre-stretch” stage. The superfine tough filaments are directionally oriented producing a fibre web sheet that is then thermally and mechanically bonded.

By varying polymer and process conditions, a range of high strength Typar® sheet structures with differing denier and physical properties can be produced. DuPont patented production technique is one of the main reasons for the unique properties of Typar® compared to other geotextiles.


High energy absorption

95% of the damages to a geotextiles occur during the installation. DuPont has developed products that ensure a total resistance to this primary challenge consequently guaranteeing a long life service.


High profitability

It is generally recognised that the use of a geotextile in construction applications is cost saving(materials and manpower savings) and performance-enhancing solution compared to traditional construction techniques.


Ease of use and installation and widely available

Each DuPont™ Typar® product has been especially developed to provide the best solutions to the particular needs of the civil engineering and construction industry challenges.
All products are easy to handle, easy to install and to remove in the case it is needed.


Certificates and durable materials

DuPont™ Typar® products are submitted to several voluntary certification systems ensuring the highest quality. Typar® is manufactured in accordance with ISO 9001, ISO 14001 and EMAS  standards. Dupont stringent quality requirements ensure that only high quality products are released to the market place. The integrated production and laboratory system ensures the manufacturing process conditions and laboratory results for every roll are traceable.
