GEOTEX 180ST PD

product data • GEOTEX 180STGEOTEX 180ST is a woven polypropylene geotextile containing heavy woven flat tape yarns produced by Propex, and will meet the following Minimum Average Roll Values (MARV) when tested in accordance with the methods listed below. These characteristics make GEOTEX 180ST ideal for the construction of embankments over soft soils, steepened slopes, and modular block and/or wrapped-face retaining walls. The geotextile is resistant to ultraviolet degradation and to biological and chemical environments normally found in soils. GEOTEX 180ST conforms to the property values listed below1 , as well as meets the requirements set forth by AASHTO M-288/NTPEP (Geotextile Specification for Highway Application). Propex performs internal Manufacturing Quality Control (MQC) tests that have been accredited by the Geosynthetic Accreditation Institute – Laboratory Accreditation Program (GAI-LAP).

The property values listed above are effective 04/2011 and are subject to change without notice.2. Values shown are in weaker principal direction. Minimum average roll values (MARV) are calculated as the typical minus two standard deviations. Statistically, it yields a 97.7% degree of confidence that any samples taken from quality assurance testing will exceed the value reported.3. Maximum average roll value.
