P.E.R. Ground System

The P.E.R. Ground System, designed for challenging excavations, combines a fiberglass-reinforced element with an expandable sheath, filled with pressurized mortar. This system improves pull-out resistance, efficiently controls mortar usage and reduces perforations by up to 45%, enhancing safety and saving resources. P.E.R. Ground is customizable in various combinations, allowing multiple functions to be performed simultaneously (e.g., P.E.R. Ground Drain for both reinforcement and drainage).
