Some products are additionally calendered. Secutex® is used for the separation of soil layers with different grain sizes as well as to establish the missing filter stability.

When applying additional earth layers over a soil with a poor bearing capacity, the elongation characteristics of the nonwoven geotextile will minimise damage during the installation process. To ensure the separation function under high rutting, Secutex® nonwoven geotextiles with high elongations are the first choice.
The high elongation capacity of Secutex® nonwoven geotextiles ensures excellent resistance to damage. This characteristic of Secutex® products allows them to easily accommodate irregular or soft sub-grades. Especially when covered with stone material, Secutex® nonwoven geotextile fibres are reoriented around the stones, preventing damage to the nonwoven structure.
As with mineral filter layers, soil retention capacity also plays an important role when using Secutex® nonwoven geotextiles. Geotextile filters must be engineered such that the mechanical effectiveness and hydraulic filter effectiveness (water discharge without loss of pressure) are equally achieved.
