Tecdren® is used in landfills and works on compressible soft soils as drainage elements that remove the water contained in the voids of the soil, which can also reduce settlement time from years to months.

Tecdren® consists of a 10 cm wide by 5 mm thick HDPE core with small channels on both sides through which the water will percolate. The core is wrapped in a non-woven geotextile blanket, which functions as a separator filter that prevents penetration and clogging of the channels by the clay soil.
