A novel approach is followed in the present research by creating a series of openings through punching the geotextile to act as a geogrid reinforcement. The geotextile reinforcement with openings is termed grid–geotextile. Due to the openings present in the grid–geotextile, both the interface frictional mechanism and passive resistance mechanism act simultaneously during testing. The model tests were performed using polypropylene geotextile reinforcement (GTX) and grid–geotextile reinforcement consisting of varying sizes of aperture (A) and rib (R): A10R15, A20R15, A30R15, A10R25, and A10R35. Regardless of the reinforcement type, a single reinforcement material was used that was placed immediately above the anchor plate. A series of 1g pullout laboratory model tests were performed using a circular plate anchor of 100 mm size (D) in the sand bed, having a relative density (Rd) of 70%. The results revealed that the reinforcement of A10R15 with 2D size (Bg) improves the anchor uplift capacity similar to that achieved with the reinforcement of GTX having size (Bg) of 5D. Furthermore, the grid–geotextile reinforcement of A10R15 shows greater improvement compared to other reinforcements. The current research also demonstrates the effect of various reinforcement geometrical parameters on anchors’ uplift capacity. Moreover, the tests were also performed by varying the configuration of the apertures of triaxial geogrid of TGG1 and TGG2 and compared to those of A10R15 while maintaining the same reinforcement geometrical parameters. Finally, the improvement of anchor pullout capacity was found to be higher with the reinforcement of TGG2. Overall, this research demonstrated the vital role played by the configuration of the reinforcement apertures (i.e., the presence of apertures within the rib of reinforcements) in improving anchor uplift capacity.
