Prevent the mixing of two different soils or materials



nonwoven geotextiles,
geonets, geocomposites

Avoid damages to a structure, a material or another geosynthetic



geomembranes, geocomposites

Fluid barrier




Restrain the lateral movement of a soil mass

erosion control

Erosion control and surfacial stabilization

geomats, geocells,
biomats, bionets
