The concept of using geotextiles in walls and steep sided embankmentsconstruction is well accepted in the developed countries and practically today, the demand for them is ever increasing .In Egypt, of course, the utility of geotextiles is still very limited to this particular area of application.. This research aimed to produce nonwoven fabrics that can be used in walls and steep sided embankments . Two kinds of textiles materials were used ,polyester and polypropylene of denier 6 to produce fabrics of 350 ,600 and 850 g/m2 weights using three puncture depths 6,12 and 18 mm with two bonding techniques ,needle punching and Calendering . Some more results were reached concerns structures and materials .
Geotextiles in walls and steep sided embankments
Surface erosion due to rain and wind cause loss of huge amount of top soil walls , hill slopes , and embankment slopes . Besides this there was problems with short –term instability in the form of deepseated rotational slippage or transverse spreading of the embankment.
