There is a problem that a large number of people are taken each time the work is carried out, the manufacturing cost is greatly increased, the productivity varies depending on the skill of the worker.

In addition, the conventional geogrid (1) (1-1) is a synthetic resin solution such as polyethylene (HDPE) to the warp (2-1) and weft (3-1) of the warp rib (2) and weft rib (3) Elongation rate was greatly increased up to 1.0% because it was used in this way. If the existing geogrid (1) (1-1) with a high elongation rate (1.0% or more) is used for civil engineering work, it will not be able to flow back to the ground firmly. In addition, the bearing capacity of the ground falls, as well as the middle portion of the geogrid (1) (1-1) is easily dropped and the weaving state is released, thereby causing problems such as ground easily falling or collapsing.
