TexDrain™ Drainage Geonets and Geocomposites

CETCO TexDrain Geocomposites are designed to provide high capacity planar flow of liquids, with integrated protection from clogging. These high quality geotextiles resist clogging of the geonet core by soil particles while protecting adjacent geomembranes from damage. TexDrain’s high strength core is also available in different thickness profiles to provide a wide range of performance attributes.

Applications
TexDrain is used as a cost effective replacement for granular drainage and gas venting systems. In cover systems, TexDrain will inhibit the accumulation of pore-water pressure above the barrier layer by providing a high capacity flow path for the drainage of excess liquids. Additionally, TexDrain may be used as a component of a gas venting system below the barrier layer, to prevent gas build up - whether generated from contained waste or from underlying soils. In bottom liner systems, TexDrain may be used as a replacement for a granular leachate collection system, or underneath the primary liner or geosynthetic clay liner as the leak detection layer. Due to their flexibility and low mass per unit area, TexDrain products are easily installed and can accommodate the most challenging structures.

Features and Benefits

  • Cost effective replacement to granular drainage systems – ensures savings on materials, transportation, installation and airspace.

  • Saves time and natural resources – preserves aggregate resources for structural applications where alternative materials can’t be used.

  • Filter, drainage, and protection layer are a single unit – TexDrain can be installed rapidly at costs lower than conventional aggregate layers.

  • Wide range of product combinations – allows performance driven product selection at an economical price.

  • Chemically resistant polyethylene and polypropylene construction – provides long life in harsh environments.

  • Exceeds EPA performance guidelines for drainage – ensuring adequate performance for a variety of conditions.

  • Exhibits high interface shear strength – allowing greater factors of safety than with granular drainage material, under the most challenging conditions.

Available Products

TexDrain is available in a wide range of product combinations allowing economical performance driven product selection.

TexDrain Geonet can be combined with a broad range of nonwoven geotextiles, thermally bonded to either one or two sides to achieve a wide range of product performance.
