ALFWEB is an engineered cellular confinement system made from alternate linking of semi-rigid panels ofpurpose designed nonwoven fabric or high-density polyethylene membrane.The system is utilized in the areas of slope protection, channel protection, load support and earth retentionstructures. The ALFWEB system dramatically improves the performance of infill materials in these applications.
The ALFWEB system can be used in many slope protection applications meeting a wide range of performancesand aesthetic requirements. The three-dimensional system confines the determined infill material to resistanticipated hydraulic stresses, inhibits erosion and prevents downward migration of embankment materials.
ALFWEB ON STEEP SLOPES
In slope protection application, the ALFWEB system prevents thedownward migration of embankment materials by functioning ascheck-dam in the upper soil layer. On vegetated slopes, itincreases erosion resistance by encapsulating and protecting thevegetative root zone, It helps prevent forming of ridges and gulliesin areas of concentrated flow over erosive soils.
The ALFWEB cellular confinement system offers a broad range of surfaceprotection treatment for all slopes. The system is engineered for flexibilityand can be combined with simple but effective anchoring techniques toallow the application of both vegetated and hard surfacing materials onsteep slopes.
