Percentual variation of weightVariation of massper unit areaTensile ResistanceDeformationTime (months)Fig. 5Variation of the deformationAfter the third month both PET and PP showed increasesin the deformation variation. At the last time the variationdecreased again. The final values of the relentionobserved were: 84.79% (PET) and 52.56% (PP). In spiteof the behavior of the curves, the PP GT presented highervariations than the PET GT. At the first month the PPshowed a high variation in deformation: the retention ofthe property was about = 62%.In general, both PET and PP geotextiles showedsignificant decreases in deformation and some variation intensile strength (see Table 2). The variations in mass perunit area may explain the oscillations in tensile properties:the behavior was very similar showing to have a relationenters the variation of the mass per unit area and thevariation of the resistance.PP geotextiles showed the highest variation (decrease) indeformation:=50%after 4 months. Both PET and PP
