Soft Non Woven & PROTEC

Soft Non Woven (SNW) geotextiles are manufactured using a process more or less equivalent to the thermally bonded Non Wovens, however, without any thermal processing. This results in greater elongation and puncture resistance.

The main functions of Soft Non Woven are protection, separation and filtration and are mainly used in conditions where both high tensile strength and high elongation are required, such as in the protection of membranes/foils in various applications and tree roots, and in the repelling of Japanese Knotweed.

Nonwoven Geotextiles (Protec)
The Protec Non Woven is characterized by a greater thickness and higher elongation than standard vernalized non-woven geotextiles. This makes these geotextiles ideal for protection and drainage applications where a thick cushioning layer and high elongation are critical design requirements.

Common application areas of the Protec include protection of costly pipeline coatings when backfilling pipe trenches, use as an erosion resistant layer under rock reinforcement in coastal defense projects and as protective attenuation for landfills and reservoirs. Due to its greater thickness, Protec non-woven geotextile offers better values for in-plane water flow than standard verniered non-woven geotextiles, allowing it to also be used as a drainage layer for certain applications.

Application SNW tbv Japanese knotweed

Deze Soft Non Woven [de TFDK40SNW] wordt ingezet om de (her)groei van de Japanse Duizendknoop te reduceren. Dit wordt gedaan door het speciaal in te pakken van de groeilocatie met dit niet-thermisch gebonden vlies. Door de hoge doorponssterkte en grote mate van flexibiliteit kan deze Non Woven de groeikracht van de Japanse Duizendknoop wortels weerstaan, voorkomt scheuren door eventuele uitstekende scherpe delen, en zorgt ervoor dat de wortels van de Japanse Duizendknoop niet of minimaal hechten aan het doek. Deze toepassing is tevens opgenomen in de handleiding ‘toepassen ondergronds worteldoek binnen stedelijk gebied ter bestrijding van Japanse Duizendknoop’, op te vragen via ons contactformulier.

Deze Soft Non Woven kan middels een ruime overlap gelegd worden, maar we adviseren om de scheidingslaag aan elkaar te verbinden middels een grondvaste dubbelzijdige (TFDK40 Geotape) kleeflaag.
