Wick drain is a geosynthetic material used for drainage aiming to increase consolidation process of foundation. Wick drain consists of two layers: filter cover is made from non-woven geo-textile from PP or PET 100% without any binding agent and drainage core from PP plastic with water ditch in both sides.

OPTIMAL DRAINAGE SOLUTION

Aritex wick drain (RID and VID) is a prefabricated drainage strip or board. The core is a highly flexible polypropylene extrusion, having maximum water flow capacity along the grooves formed longitudinally on both sides of the core. The filter fabric on our drain is made from strong, durable, non-woven geotextile, having a very high permeability. The geotextile fabric serves as a filter to allow passage of groundwater into the drain core while preventing piping of fines from the adjacent soils.  Water is absorbed through the geotextile filter of the wick drain, soaked and flows into the wick drain core smoothly.

Prefabricated vertical drain

RID and VID prefabricated drain with its outstanding properties of being anti-bacteria, anti-organic bacteria, corrosion resistance makes it an economical solution to long-term foundation settlements by accelerating the consolidation of soft soils.

board drain

Board drain is a board-shaped material that is used to reduce consolidation time and increase foundation shear strength of soft clay soils. Similar to prefabricated vertical drain, board drain consists of a filter layer and a core layer.

VARIOUS APPLICATIONS

The works that can apply absorbent wicks to handle a variety of soil requirements, including highways, bridge leading roads, airport runways, railways, ports, petroleum depots, construction projects. on soft ground and with dynamic load. At the same time, absorbent wicks are also used for the purpose of treating the environment in contaminated soil areas, absorbing groundwater through the contaminated soil layers, carrying water-soluble pollutants to the surface. to handle.
