ABSTRACT:
The present invention relates to a process for forming a polymeric pre-stretched grid for supporting a structure, such as an earthwork, wherein a suitable polymeric material, e.g. polyethylene, is used to make thin polymer strips by a molding machine, these strips are fully stretched by a pre-stretching machine so as to rearrange long bonds of polymer molecules to form the pre-stretched strips with high tensile strength, then these pre-stretched strips are crossed over each other longitudinally and transversely in line with a pre-set width by a machine (or manually) and the crossings of longitudinal and transverse network plies are united by gluing or hot fusion or otherwise to form a pre-stretched grid.
