Rock© PEC

Rock® PEC is a biaxial geocomposite.

Rock® PEC is a high tensile composite material for soil stabilisation and surface reinforcement, consisting of mechanically bonded nonwoven filament fabric and sewn-on polyester yarns.
Rock® PEC was developed to combine the functions of reinforcement, deformation limitation, separation, filtering and drainage. This combination makes Rock® PEC particularly suitable for reinforcement of mixed or fine-grained soils.

Due to its ability to absorb and drain pore water, excess pore water pressure can be relieved and load-bearing properties improved when installed in cohesive soils. This leads to significantly higher soil strength values compared to geogrids or fabrics.
