HDPE composite Drainage Geonet is commonly used as a salt barrier. HDPE 3D Salt Barrier Drainage Geonet A nonwoven geotextile fabric wrapped around a high-density polyethylene core makes up the composite drainage mesh. This innovative design enables the mesh to effectively filter and drain excess water, which promotes proper soil drainage and prevents salt and other harmful contaminants from accumulating. Employing the composite drainage mesh as a salt screen barrier in construction projects paves the way for long-lasting soil stability and increased soil health while minimizing the need for costly remediation measures in the future.
