Abstract
A method of making a biplanar net structure usable to provide reinforcement in civil engineering and/or landfill applications by extruding first and second linear arrays of plastic filaments into first and second sets of spaced-apart grooves provided in a filament receiving member. The grooves of the respective sets cross each other, and the plastic filaments bond to each other at the crossing points to provide a biplanar net structure. The net structure then is uniaxially or biaxially stretched. The apparatus employed to carry out the method and the oriented biplanar net structures also form a part of this invention.
