Geomembranes Geomembranes are impermeable, making them watertight. They are used for various functions: waterproofing liquid storage tanks; sealing cofferdams to deflect water; covering the bottom and sides of a temporary diversion channel; containing and separating contaminated soils; temporarily covering bare soil and storing [...]



Geogrids The function of geogrids is soil reinforcement and stabilization. They are composed of polymer-based geosynthetics in the form of a grid, meaning that the total surface area of the openings is greater than that occupied by the ribs and cross-overs making up the geogrid mesh. Geogrids [...]


High-performance geotextiles
