PROBLEM TO BE SOLVED: To obtain a three-dimensional netlike body a having high compression stress and a slight reduction in amount of thickness even under a high load, retaining a high porosity, capable of quickly draining overflow water, a three- dimensional netlike body having improved packability of soil and a material of a three-dimensional netlike body structure as a netlike body having bulkiness and high rigidity which is made by bonding and constructing these three- dimensional netlike bodies and has about several dozen cm that has been impossible in a conventional three-dimensional netlike body and is useful as a material for civil engineering. SOLUTION: A great number of continuous filaments which are composed of a thermoplastic synthetic resin and have 0.1-1.5 mm thickness are piled in a netlike form, fused, bonded and integrated at their crossing points to form a netlike body having 0.1-4 mm substantial thickness. The netlike body is in a pleat form in a cross section in the thickness direction and is alternately provided with a plurality of ridge parts and channel parts continuous in one direction and is made into a mat shape provided with large voids by unevenness of the netlike body. |
