AS <br />lon; as this formula!ioA remains'the $ame the W resistance of a geotextiles does not change. Therefor--, <br />GSE derforms LTV testing only once per resin formulation. The testing is performed according to ASTM <br />Test Rethod D 4355'and results are included on GSE gebtextile specification sheet • C=ently, all GSE <br />geocetiles meet or eceeed & •value of 70go strength retained atet 500 hours of W exposure, GSE will <br />meet or exceed this value for the referenced project. <br />Mhougb GSE gcotextiles are bmanufaeta ed using one of the best available atttioxident packages, we <br />reconasrend covering the geotextiles within X5 days of exposure to direct Sunligght. This period does not <br />includb tune during which geotextats rolls remain on site cw. e: in black sbri k -wrap- Oq-, �eotextile <br />reco akeadation is based on W performance data published in technical literature indicating <br />strength can decrease sharply after prolonged exposure w Sunlight. <br />Actual idata from an independent laboratory can be supplied upon request. <br />C�4 I I �, <br />Charicio.
