The difference between the filter mechanism established by thick geotextiles, compared with that established by thin geotextiles, is another drawback of strip drains. With the thin geotextile, the very fine soil particles initially pass through, leaving the large soil particles to bridge across the pore openings in the geotextile surface. This process induces a beneficial filter layer within the adjacent soil. In the case of the thick felt-like geotextiles used for strip drains the pore structure is complex and the soil particles do not readily pass completely through. 2, record 1, English, - thick%20geotextile

[Fabrication d'un géotextile] Non-tissé épais. Ces matériaux très volumineux, et à structure très lâche sont très souvent réalisés à partir de fil monofilament de gros calibre (diamètre élémentaire de l'ordre de quelques 1/10 de mm). La réception de ces fils a lieu sur un convoyeur, de sorte que la température de ceux-ci soit voisine du point de collage de la matière. Une liaison entre les brins s'opère, puis un brusque refroidissement dans l'eau fige les points de collage. Selon la forme du tablier de réception des monofilaments, on peut atteindre des épaisseurs de nappes de l'ordre de 30 à 40 mm. 3, record 1, French, - g%C3%A9otextile%20%C3%A9pais

A couple of studies have attempted to assess the long-term performance of geotextiles in erosion prevention structures.... The method employed in both cases, was to test samples recovered from sites where geotextiles had been in service for periods of 5 to 12 years. Examination of samples of thick non-woven geotextile revealed that, in some instances, a large quantity of soil particles had become trapped, filling over half the volume of pores in the geotextile. Although this degree of partial clogging might at first appear ominous none of these installations was actually at risk. This was because, even in this partially clogged state, the ratio of geotextile permeability to soil permeability exceeded 5. Heerten comments that this should guarantee sufficient long-term permeability. 1, record 3, English, - long%2Dterm%20permeability

(...) quelques exemples d'endommagement des structures côtières appellent d'urgence une étude de résistance à long terme. Un programme de recherche a donc été élaboré en vue de mettre au point des recommandations d'essai des géotextiles, des règles en matière de filtration et l'élucidation de la résistance à long terme des tissus. Cet article traite des procédures d'essai en relation avec les dimensions des mailles et la perméabilité à l'eau des tissus. 2, record 3, French, - perm%C3%A9abilit%C3%A9%20%C3%A0%20long%20terme

For filtration design it is necessary to know the amount of openings. For a thick product such as a needlepunched nonwoven, a mat, or a net, the amount of openings is characterized by the porosity ... For thin products such as woven geotextiles, the amount of openings is characterized by the percent open area ... 2, record 4, English, - thick%20non%20woven

Clogging, blocking and blinding. If the geotextile pore openings are slightly too small, then there will be insufficient initial wash-through of fine soil particles to promote the rapid formation of an efficient graded filter in the adjacent soil. Where the geotextile pore openings are even smaller, then there is a serious risk that either blinding, severe blocking or severe clogging will develop with time. Blocking is where soil particles resting on the surface of the geotextile, either totally or partially obstruct the pore openings.... Blinding is a special form of severe blocking, where the soil grading permits the suffusion of fine soil particles which are too large to pass through the geotextile.... Where the size of many of the soil particles is very close to that of the geotextile pore openings, then they are likely to enter the pores and become trapped within the geotextile. This can cause severe clogging which is most likely to arise in thick non-woven geotextiles with a complex pore structure. 3, record 5, English, - clogging
