The application of geotextiles for prefabricated drains. Until the seventies, vertical drainage systems were mainly being applied in the form of sand drains. This method consisted of forming holes in the ground by means of water jets in combination with drills or bailers, until the desired depth was reached. These holes were then filled with sand..... Nowadays there are many brands and types of drains available. These can be roughly divided into the following groups: Non-woven drains.... Composite drains....

On peut [...] assimiler un géotextile à un drain capable de dissiper les pressions interstitielles, de collecter et de conduire le fluide vers un exutoire. Cette capacité à remplir efficacement le rôle de drain sera d’autant plus grande que la transmissivité du géotextile sera élevée. La fonction drain est particulièrement intéressante, car les géotextiles se présentent sous forme de nappes; leur surface de contact est importante, et par conséquent leur possibilité de captage d’eau est grande.  3, record 1, French, - drain%20pr%C3%A9fabriqu%C3%A9%20Sandwick

Forages emplis de sable fin, par exemple, dans le but de réduire la durée des tassements. Ils servent également d’exutoire à l’eau des lentilles plus perméables que les argiles. Ils ne modifient pas la vitesse de tassement de certaines vases mais permettent alors d’annuler la pression des pores. Il faut les mettre en œuvre plusieurs mois avant le début de la construction et éventuellement surcharger le sol.  1, record 2, French, - drain%20vertical

... fabric-enclosed sand drains. [The method] consists of a polyethylene monofilament tube of varying diameter running the length of the compressible stratum. This net-type tube with 1.2 by 1.6 mm openings is inserted into a crane-mounted casing that drives the assembly into position for sand filling. The casing is withdrawn by a crane while the fabric-filled sand column is left behind with the aid of applied air pressure ... As with other applications of fabrics in drainage, the proper fabric can be considered to be part of the drainage system, not merely used as a separating medium.  1, record 5, English, - fabric%2Denclosed%20sand%20drain
