Drainage Geonets

HAOYANG HYD series Composite geonet for drainage, the drainage net is manufactured from HDPE,adding anti-aging agent and using special plastic processing technology and machinery, through heating, extrusion-molding and cooling extrusion to produce two or three staggered ribs to form three-dimensional spatial smoother drainage strucure and overlapping network structure created by two layers of interlocked ribs with compatibility with plastic raw materials, this composite drain net can bear high mechanical loads, and geotextile effectively prevent all kinds of impurities from clogging the mesh.

Bi-planar drainage geonets are also known as two-dimensional drainage geogrids and double layer geosynthetic drainage nets. The three-dimensional drainage net is also called a tri-planar drainage net, tri-dimension compound geonet, and 3D drainage net. Based on customer requirements, these drainage geonets can be combined with other materials, including geotextiles and geomembranes to form a multiple protection system with filtration, drainage, ventilation and impermeability purposes for various projects.

Production process

HAOYANG HYD series drainage geonets are manufactured using high density polyethylene (HDPE) with added aging resistant agents and a manufacturing process that uses special plastic processing technology and machinery.

Manufacturing involves heating, extrusion molding and cooling extrusion in order to produce two or three staggered ribs to form a 3D spatial smoother drainage structure and overlapping network structure. This structure is created using two layers of interlocked ribs that are compatible with plastic raw materials.

This ensures the composite drain net can then bear high mechanical loads, as well as effectively preventing impurities from clogging the mesh, guaranteeing a smooth performance that will satisfy customer requirements for keeping their projects working smoothly.


1. High tensile mechanical properties, long service life, strong load-carry capacity
2. Acid and alkali resistance, fitting for various special projects
3. Excellent drainage and hydraulic conductivity without causing clogging on the drainage system
4. Convenient installation that is not affected by the weather
