Geonets Coastal Engineering — Practical Guidance for Shoreline Protection
. When correctly specified and installed, geonets offer a low-maintenance, high-performance drainage layer in many shoreline systems. Learn more about Geofantex® Geonet solutions for coastal and civil applications. What are geonets and why are they relevant to coastal engineering? Geonets are three-dimensional polymer drainage cores (typically HDPE or polypropylene) that provide high in-plane transmissivity and resist compression and chemical attack. In coastal engineering they perform three key roles: (1) drainage behind revetments and seawalls to relieve pore pressures, (2) filtration/erosion control when used as part of a geocomposite with a filter geotextile, and (3) energy dissipation support when combined with rock or mattress systems to reduce scour and displacement.
