The present invention provides geogrids (10) for reinforcing soil material which include a first plurality of spaced-apart generally parallel members (12) comprising a thermoplastic matrix material (44) reinforced with fibers (46) having a predetermined deformation temperature which is greater than a predetermined deformation temperature of the thermoplastic matrix material (44); and a second plurality of spaced-apart generally parallel thermoplastic members (58) positioned adjacent to and forming a plurality of intersections (26) with at least a portion of the first plurality of strands (12), wherein average thickness of an intersection (26) of the plurality of intersections is greater than average thickness of a corresponding member of the first plurality of members (12) which is adjacent to the intersection (26).
