Nonwoven needlepunched geotextiles are a suitable material for the construction of geotextile reinforced earth structures. With a correct design they can be used even for structures with high loading requirements. Simple design methods (earth pressure method) can be applied when an adequate factor of safety is applied to the tensile strength of the geotextile. Provided carefull installation and good compaction of the fill material are achieved, the settlements of such a structure are negligible. These requirements are obligatory and of highest importance in any reinforced soil structure. Temporary geotextile reinforced earth structures using low modulus nonwoven geotextiles are a technically and economically sound alternative to sheet pile walls, based on quick installation and low demand for space. The actual in soil stress-strain behaviour of nonwoven geotextiles made from Polypropylene shows an increase in modulus and significantly lower creep behaviour.
