Geotextiles separate adjacent soil types or fill materials preventing them from becoming intermixed. They are used in the form of durable,robust nonwoven or woven fabrics and/or composites manufactured of synthetic raw materials able to withstand high loads. Common
applications include road and railway construction, hydraulic engineering, and construction of riding and sports grounds. The selection of the appropriate product depends on the grain size distribution of the base course materials and the expected operational loads.


Mechanically bonded nonwovens are especially suitable for this
function since they adjust themselves very well to irregular subsoils
and also to soft soils due to their high elongation capacity. This
elongation capacity is important to accommodate the penetration of a
stone. The fibres lay themselves around the stone and prevent the
nonwoven structure from being damaged.
