LotrakŪ 25R: Technical
Lotrak® Geotextiles are manufactured under a Quality Management Scheme in accordance with provisions of ISO 9001.
Tested, independently, in accordance with European Standards, Lotrak® geotextiles comply fully with all aspects of the CE Regulations and are marked accordingly.
Lotrak® geotextiles used in each application have varying characteristics that are key to their success. In order to summarise these characteristics, the European Standards Committee (CEN) has documented the required characteristics for geotextiles for each specific end use.
A separate European standard covers each application and stipulates the different functions, characteristics and test methods to be used. One standard, EN:13249, lists the mechanical and hydraulic properties important to the functions of Filtration, Separation and Reinforcement when used in the construction of roads and other trafficked areas.
