Geogrids IYSGFG-Neftegas-GRUNTSET consist of two systems of rovings or complex yarns sewn together with a third (sewing) yarn and impregnated with complex polymer mixtures based on binding latexes.
|
These geogrids are used in dirt constructions on weak bases as a reinforcing interlayer ensuring general stability of the mound. They allow to reduce the required volume of the applied materials and decrease variations of settlement reducing ruttiness from traffic circulation and creating favourable conditions for compacting of the lower layers of the mound.
The special impregnation of the Grids ensures their resistance to possible aggressive actions during building and operation (aquatic environment, pH from 4 to pH 10, action of negative and positive temperatures).
These geogrids are made of glass fibre and used for reinforcement of dirt structures.
